Types of Welding Processes

There are four main groups of welding processes. These are arc welding, resistance welding, gas welding, and brazing. Each group uses its tools and ways to weld. Some groups, like OSHA, AWS, and ASME, make rules for safety and quality. These rules help keep workers safe and make sure welds are strong. You can see how these rules fit with welding in the table below:

AFI Industrial Co., Ltd. knows all the main welding types. Their team can pick the best process for your job. Next, you will learn about the top 10 welding processes.

Arc Welding

Arc welding is the most commonly used welding type. It uses an electric arc to join metal pieces. The arc makes a lot of heat and melts the metal edges. When the metal cools, it sticks together very well. Arc welding machines are easy to move and use. You can use them in many places, like factories or outside.

There are different kinds of arc welding. Each kind is good for certain jobs. Some types are stick welding, MIG welding, TIG welding, flux-cored arc welding, plasma arc welding, and electroslag welding. Stick welding is good for fixing things outside. MIG welding is fast and used in car factories. TIG welding is neat and used for planes and nuclear work.

Arc welding can join many metals, like steel, aluminum, titanium, and nickel alloys. You can use it even if the metal pieces do not fit just right. This helps when working in tough places. You can also change the voltage and speed to match the job.

Many workers use arc welding. Car makers, shipbuilders, and builders use it a lot. It is also good for fixing and keeping things working. The different types let you pick for speed, neatness, or strong welds. Argon gas is often used to keep the weld clean and strong.

Tip: If you need a strong weld in hard places, arc welding is a good pick. You can choose the type that fits your job best.

Resistance Welding

Resistance welding is another big group of welding processes. It uses pressure and electric current to join metal. The heat comes from the metal fighting the electric current. You do not need extra filler for this welding.

Car factories use resistance welding a lot. Spot welding joins car panels, wheels, and pipes. Most car welding uses this method. It is also used for frames, parts, and engines. Planes, electronics, and home items use it too.

Here is a table that shows where resistance welding is used:

Resistance welding is fast and can be done over and over. This makes it great for making lots of things.

Gas Welding

Gas welding is one of the oldest welding types. It uses a flame from burning gases, like oxygen and acetylene, to melt and join metal. This way works best for thin metal, pipes, and tubes.

People use gas welding for fixing and keeping things working. It is common in car shops, on farms, and in heating and cooling work. You can weld gas tanks, water pipes, and boilers. Gas welding is easy to move and set up. You can use it in small spaces. It is also used for making jewelry and fixing cast iron.

Gas welding lets you control the heat and weld. This is good for careful work on thin metal. Newer ways have replaced gas welding in some jobs, but it is still useful for special work.

Now you know the main welding types. Next, you will learn more about each one and how AFI Industrial Co., Ltd. can help you pick the best.

Brazing

Brazing is a special way to join metals. You use a filler metal that melts at a lower temperature than the main pieces. The base metals do not melt during brazing. The melted filler metal moves into the gap by capillary action. When it cools, it forms a strong bond.

You can use many heat sources for brazing. Some common ones are a torch, furnace, induction heater, or resistance heater. Brazing works at over 840°F (450°C), but this is cooler than most welding. The lower heat keeps the base metals strong. It also helps stop warping or bending.

Brazing is different because it joins many kinds of metals. You can connect copper to steel or even metal to ceramic. This is hard to do with regular welding. Brazing also makes for cleaner joints. You do not need much grinding or finishing. Many industries like brazing for its neat and careful results.

Here is a table that shows how brazing and welding are different:

You can find brazing in many places. Electronics makers use it for tiny parts. Aerospace companies use it for special alloys. Car makers use brazing for radiators and air conditioning. HVAC workers use it to join copper pipes. Jewelers use brazing to make fine jewelry.

Brazing is easy to learn. You do not have to watch the heat as closely. It is also easier to automate. This helps factories make lots of parts fast. Brazing works for both small and big jobs.

AFI Industrial Co., Ltd. offers advanced brazing services. Their team can join copper, steel, aluminum, and ceramics. They use modern tools to keep joints clean and strong. You get good results with less risk of damage.

Tip: If you need to join different metals or want a clean, strong joint with less heat, brazing could be your best choice.

Brazing gives you many options and careful work. You can use it for tiny electronics or strong machine parts. With AFI’s help, you get high-quality brazed joints that last.

Shielded Metal Arc Welding

Process

Shielded metal arc welding, also called stick welding, is one of the oldest arc welding methods. You use a metal rod, called an electrode, that has a special coating. When you strike the electrode against the metal, it creates an electric arc. This arc melts both the electrode and the base metal. The coating on the electrode turns into a gas and a layer of slag. These protect the weld from air and keep it clean.

You start by cleaning the metal to remove dirt and oil. Next, you pick the right electrode for your job. You set the welding machine to the correct current and polarity. Then, you hold the electrode at the right angle and move it along the joint. You need to keep a steady hand to make a strong weld. After you finish, you check the weld for cracks or holes. Sometimes, you use special tests like X-rays or sound waves to look inside the weld.

Many standards help you make safe and strong welds. Some of these are AWS D1.1 for structural steel welding, ISO 2560, and EN 499. These rules tell you how to set up the welding process and how to check your work.

Welding Applications

You will find shielded metal arc welding in many industries. It works well for outdoor welding and heavy-duty jobs. Construction workers use it for structural steel welding, pipeline building, and making strong frames. Shipbuilding uses this arc welding process to join large sections of ships. You also see it in manufacturing, where you need tough welds that can handle heavy loads.

Here are some common applications for shielded metal arc welding:

• Building bridges and skyscrapers
• Repairing heavy equipment
• Welding pipelines for oil and gas
• Assembling large sections of ships in shipbuilding yards

The process works in any position—flat, vertical, or overhead. You do not need extra gas because the electrode coating makes its shield. This makes the welding process simple and portable.

You save money because the setup costs less than other arc welding methods. The welds are strong and have good durability, even in harsh weather. You can use this method for repairs, new builds, and fieldwork. The process is easy to learn, so you can train new welders quickly.

Tip: If you need a strong weld in a hard-to-reach place or outside, shielded metal arc welding is a smart choice. You get reliable results with simple tools.

Gas Metal Arc Welding (MIG)

Process

Gas metal arc welding, also called MIG welding, is a popular arc welding process. You use a welding gun that feeds a thin wire electrode into the weld joint. The wire melts and joins the metal pieces together. A shielding gas, like argon or carbon dioxide, flows out of the gun to protect the weld from air. This keeps the weld clean and strong.

You can use gas metal arc welding for both thick and thin metals. The process works well with steel, aluminum, and other alloys. The equipment includes a welding gun, a wire feed unit, a power supply, and a gas tank. You can control the speed of the wire and the amount of gas. This helps you make neat, even welds.

Gas metal arc welding is fast and easy to learn. You can use it by hand or set it up for robots. Many factories use this process because it works well for mass production. You do not need to stop and change electrodes, so you can weld for a long time without stopping. The process makes little spatter and no slag, so you spend less time cleaning up.

Tip: If you want to weld quickly and get clean results, gas metal arc welding is a smart choice for your project.

Applications

You will find gas metal arc welding in many industries. It is one of the most common arc welding methods for making cars, buildings, and machines. Here are some main applications:

• In the automotive industry, you use gas metal arc welding to make car frames, body panels, and exhaust systems. The process is fast and works well for both steel and aluminum parts.
• In construction, you use this arc welding process to join steel beams, columns, and frames. It is important for building bridges, pipelines, and large buildings.
• Aerospace and shipbuilding also use gas metal arc welding for strong, precise welds on thin and thick materials.
• You can use this process for repair work and for making new products in factories.

Gas metal arc welding is valued for its speed, precision, and ability to handle many types of metals. You can use it for both small and large projects. The process works best indoors or in controlled environments because the shielding gas cannot blow away outside.

Note: Gas metal arc welding is a top choice if you want fast, clean, and strong welds for many types of projects.

Gas Tungsten Arc Welding (TIG)

Process

Gas tungsten arc welding, or TIG welding, gives you the most control. You use a tungsten electrode that does not melt. The electrode sits in a torch. The torch sends out shielding gas, like argon or a mix with helium. This gas keeps air away from the weld. You can change the heat with a foot pedal or hand switch. This helps you control the weld as you work. You often add filler metal by hand for extra strength.

First, set up the TIG welder and pick the right current. Use AC for aluminum or magnesium. Use DC for steel, stainless steel, or titanium. Pick the right tungsten electrode for your metal. Clean the metal to remove oil, rust, or dirt. Hold the parts together with clamps or tack welds. Hold the electrode close, about 1/8 inch from the metal. Start the arc. Move at a steady speed and control the heat. Add filler rod if you need it. When you finish, clean the weld to remove leftover stuff.

You need a TIG welder, tungsten electrodes, filler rods, shielding gas, a torch, and safety gear. This process is best for jobs that need neat, careful welds.

Applications

Gas tungsten arc welding is used in many jobs that need strong, clean welds. This welding is common in aerospace for thin parts and space vehicles. TIG welding is used for small tubes, like those in bikes. It is also good for fixing aluminum and magnesium parts.

Some common uses are:

• Welding stainless steel, aluminum, and other metals that are not iron
• Making exhausts, fuel lines, tanks, and engine parts for planes and cars
• Sealing nuclear fuel canisters
• Making food and drink equipment that needs smooth, clean welds
• Joining pipes that must not rust

TIG welding is very flexible. You can use it for custom metal work, repairs, and jobs that need nice-looking welds.

Pros

Gas tungsten arc welding has many good points over other welding types. You can control the heat and filler metal very well. This helps you make strong, clean welds with no dirt.

TIG welding works with many metals, like stainless steel, aluminum, magnesium, copper alloys, and nickel alloys. You can weld thin metal without holes or warping. The welds look smooth and neat. TIG welding is good for tricky jobs that need care and strength.

Tip: If you want a high-quality weld on thin or special metals, pick gas tungsten arc welding. You will get good results and can use it for many jobs, like pipes and careful factory work.

Flux Cored Arc Welding

Process

Flux cored arc welding uses a special wire with flux inside. The wire is hollow and filled with flux. When you weld, the wire goes through the welding gun. The arc’s heat melts the wire and metal pieces. The flux inside the wire makes a gas shield. This gas keeps the weld safe from air. The weld stays clean and strong.

You can use this welding with or without extra gas. Some wires need shielding gas, but others do not. This makes the process flexible for many jobs. You can weld outside, even if it is windy. The flux also makes a layer of slag on the weld. You must chip off the slag after the weld cools.

The equipment has a wire feeder, a power supply, and a welding gun. The process is semi-automatic. You hold the gun, but the wire feeds by itself. This is faster than stick welding, which uses rods you move by hand.

Tip: If you need to weld dirty or rusty metal, flux cored arc welding works well. The flux helps protect the weld on less clean metal.

Applications

Many industries use flux cored arc welding. It is popular because it is fast and can do many jobs. Here is a table that shows where you might use this welding:

You can use this welding for bridges, ships, and fixing machines. It is also good for pipelines and tanks. The process is great for big jobs because you can weld for a long time. The wire keeps feeding, so you finish work quickly.

Pros

Flux cored arc welding has many good points over other welding types:

• You get high efficiency. The deposition rate is up to 90%.
• Welding is 1.5 times faster than manual arc welding in flat spots. In other spots, it can be 3 to 5 times faster.
• You can weld in any position—flat, up, or overhead.
• You can weld outside, even if it is windy, because the flux core protects the weld.
• The process is very flexible. You can use it on thick or thin metal, clean or rusty surfaces.
• The arc is steady, and there is little spatter. You spend less time cleaning up.
• The wire keeps feeding, so you do not stop to change rods.

Note: Flux cored arc welding is a smart pick if you want fast, strong welds in tough places. You can use it for many jobs, from building to repairs.

Submerged Arc Welding

Process

Submerged arc welding is a special type of arc welding. You use it when you need to join thick steel plates or make long, strong welds. The process starts when you clean and set up the metal pieces you want to join. You place the workpieces close together and make sure they are in the right position.

Next, you cover the area to be welded with a layer of granular flux. This flux looks like sand and protects the weld from air. You use a tubular electrode wire that matches the metal you are welding. The arc forms between the electrode and the metal, but you cannot see it because the flux covers it. The arc melts the electrode and the base metal, creating a pool of molten metal. The flux melts too and forms a layer of slag on top. This slag keeps the weld clean and strong.

You keep feeding the electrode wire into the weld pool. The welding head moves along the joint, making a long, even weld. After the weld cools, you remove the slag by chipping or grinding. You may also inspect the weld to make sure it is strong and free of defects.

The main equipment you use for submerged arc welding includes:

1. A power source that gives a steady current or voltage.
2. A welding head or boom to hold the torch.
3. A wire feeder for the electrode.
4. A flux hopper to deliver the granular flux.
5. A system to collect and reuse leftover flux.
6. Cooling devices to protect the equipment.
7. A control panel to set welding parameters.

This process is different from other arc welding methods because the arc stays hidden under the flux. You get deep penetration and strong welds, especially on thick materials.

Applications

You will find submerged arc welding in many heavy industries. This arc welding process is perfect for jobs that need strong, reliable welds on thick steel. Here are some common uses:

• Shipbuilding: You use submerged arc welding to join thick steel plates for ship hulls, decks, and bulkheads. The process creates strong, corrosion-resistant welds that last a long time.

Plasma Arc Welding

Process

Plasma arc welding is a special type of arc welding. You use a non-consumable tungsten electrode to create an electric arc. This arc forms inside a small copper nozzle. The nozzle squeezes the arc into a tight, hot jet called plasma. The plasma jet can reach temperatures up to 28,000°C. This high heat melts metal quickly and with great control.

You can adjust the plasma arc welding process for different jobs. Microplasma mode uses very low currents, from 0.1 to 15 amps. This lets you weld thin sheets and tiny parts without burning them. Keyhole mode uses high currents, over 100 amps, to make deep, narrow welds in thick metal. You can also use different gases, like argon or helium, to protect the weld and make it even hotter.

The equipment for plasma arc welding includes a power supply, a water-cooled torch, and controls for gas flow and current. You can set the machine to weld thin or thick materials. The focused arc gives you steady heat and less distortion. You get clean, strong welds every time.

Tip: Plasma arc welding gives you more control than other arc welding methods. You can weld very thin or very thick metals with the same machine.

Applications

You will find plasma arc welding in many high-tech industries. This arc welding process is perfect for jobs that need precision and strength. In aerospace, you use plasma arc welding to join thin parts for airplanes, fuel tanks, and engine parts. The process makes strong, light welds that meet strict safety rules.

• Longer electrode life and reliable arc starting improve your workflow.

Note: Plasma arc welding stands out when you need high-quality, precise welds for advanced projects. You get the best mix of speed, control, and weld quality.

Laser Beam Welding

Process

Laser beam welding uses a powerful, focused laser to join metals. You direct the laser at the joint, and the intense light melts the metal quickly. The process creates a small, deep weld with very little heat spreading to the rest of the part. You can control the laser’s power, speed, and focus to match the thickness and type of metal. This lets you make either shallow or deep welds.

You can use different techniques with laser welding. Conduction welding works well for thin materials and makes shallow welds. Keyhole welding is best for thick parts and creates deep, narrow welds. Transition welding combines both methods for special jobs. You can also use shielding gases, like argon or nitrogen, to protect the weld from air and keep it clean.

Laser welding machines have advanced controls. You can set the laser’s power, spot size, and speed with great accuracy. The process is fast and works well with robots. This means you can run production lines all day with little downtime. The focused beam keeps the heat-affected zone small, so your parts stay strong and do not warp.

Tip: Laser welding gives you precise control over the weld, making it perfect for jobs that need accuracy and speed.

Applications

You will find laser welding in many high-tech industries. The process is popular because it makes strong, clean welds with little distortion. Here are some main uses:

Note: If you need fast, clean, and precise welds, laser welding is a top choice for your project.

Electron Beam Welding

Process

Electron beam welding joins metal using a focused beam of fast electrons. First, you clean the metal parts to remove dirt and oil. This helps make the weld strong. Next, you put the parts inside a vacuum chamber. The vacuum keeps air out and stops the metal from rusting.

Inside the chamber, an electron gun makes a beam of electrons. The gun uses very high voltage, from 20,000 to 150,000 volts. Electromagnetic lenses focus the beam into a tiny spot. When the beam hits the metal, it melts the surface. This makes a deep and narrow weld. You can change the speed and energy for different metal thicknesses. After welding, let the parts cool. Then, check the weld to make sure it is good.

The main equipment you need includes:

• An electron gun that makes and focuses the beam
• A vacuum chamber that keeps air out
• A high-voltage power supply
• Electromagnetic lenses for controlling the beam
• A cooling system to protect the machine
• Monitoring tools to check the weld

Tip: The vacuum helps you get clean and strong welds with almost no dirt.

Applications

Electron beam welding is used in jobs that need strong and exact welds. Aerospace companies use it for engine parts like turbine blades and compressor disks. They also use it for big parts like fuselages and wings. This process works well for rocket nozzles and combustion chambers. It can handle thick and strong metals.

Car factories use electron beam welding for gears, shafts, and engine blocks. It is also used for battery parts in electric cars. The process lets you weld tricky shapes and join different metals. You get fast and accurate welds. This helps when making lots of parts.

Here is a table showing some key uses:

Note: The vacuum and focused beam make this process great for parts that must be strong and light.

Pros

• CNC controls help you make exact welds every time.

Callout: If you need strong and clean welds on tough or thick metal, electron beam welding gives you the quality and accuracy you need.

Resistance Welding

Process

Resistance welding joins metal pieces using heat from electricity. You press the metal parts together. Then, a strong electric current goes through them. The metal gets hot where they touch. This heat melts the surfaces, so they stick together. You do not need extra filler or gas for this.

There are different types of resistance welding. The main ones are:

• Spot Welding: You join two thin metal sheets at small spots. Copper electrodes press and heat the metal.
• Seam Welding: You make a long weld along a joint. Rotating wheel electrodes press and heat the metal as it moves.
• Projection Welding: You weld at many points at once. Raised bumps on one metal piece help make the welds.
• Flash Welding: You join big parts by clamping them. Current melts the ends, then you press them together.

You control the time, pressure, and current for each weld. This helps you get enough heat and a strong joint. Resistance welding machines can be used by hand or run by themselves.

Tip: Resistance welding works best with metals that carry electricity well, like steel, stainless steel, and aluminum.

Applications

Resistance welding is used in many industries. Car factories use spot welding to make car bodies, doors, and frames. Appliance makers use it for fridges, washing machines, and ovens. Electronics makers use it to join wires and small parts.

• Automation: You can use robots and machines for big batches.

Note: If you want a fast, clean, and reliable way to join metal sheets or wires, resistance welding is a smart choice. You will see it in many things you use every day.

Oxy-Acetylene Welding

Process

Oxy-acetylene welding uses a flame to join metals. You mix oxygen and acetylene gas in a torch. When you light the torch, the gases burn and create a very hot flame. This flame can reach temperatures above 6,000°F (3,300°C). You hold the torch and move it along the joint where you want to weld. The flame melts the edges of the metal pieces. You can add a filler rod if you need extra metal in the joint. The melted metal flows together and forms a strong bond when it cools.

You control the size and shape of the flame by adjusting the valves on the torch. A neutral flame works best for most metals. You can also use a carburizing or oxidizing flame for special jobs. Before you start, always clean the metal to remove oil, rust, or paint. This helps you get a clean weld. You wear safety gear like goggles, gloves, and a welding jacket to protect yourself from sparks and heat.

Tip: Always check your gas hoses and connections for leaks before you start welding. Safety comes first.

Applications

You can use oxy-acetylene welding for many types of jobs. This process works well for thin metals and small repairs. Many auto repair shops use it to fix car frames, exhaust pipes, and body panels. Plumbers use it to join copper pipes. Artists use oxy-acetylene welding to create metal sculptures and decorative pieces.

Farmers and maintenance workers often use this method for on-site repairs. You can weld, cut, or even heat metal parts with the same torch. This makes oxy-acetylene welding very flexible. You do not need electricity, so you can use it in remote places.

Here is a table showing common uses:

Pros

Oxy-acetylene welding gives you several advantages:

• Portability: You can move the gas tanks and torch almost anywhere. This helps you work in the shop or out in the field.
