Carbon steel has a relatively low cost and its main components are iron and carbon. Low-carbon steel has excellent welding performance, high strength, and is less likely to produce hardened structures and cracks during welding. It is widely used in construction, Bridges, mechanical manufacturing and other fields.
The welding performance of alloy steels (such as manganese steel, chromium-molybdenum steel, etc.) is closely related to the content of their alloying elements. Special welding materials and process parameters need to be matched according to the specific composition. We formulate personalized welding plans through material analysis to ensure welding quality.
Stainless steel is corrosion-resistant, has high strength and good thermal stability. During welding, it is sensitive to hot cracks and prone to intergranular corrosion and deformation. We use processes such as inert gas shielded welding (TIG/MIG), laser welding or plasma welding to strictly control the interlayer temperature to inhibit carbide precipitation. After welding, it undergoes acid washing and passivation treatment to restore its corrosion resistance. It can ensure the long-term stable use of the weld seam in harsh environments.
The high-temperature resistance and corrosion resistance of nickel and nickel-based alloys require the selection of matching dedicated welding materials during welding, and special processes such as inert gas shielded welding should be combined. We ensure that the performance of the welded joints meets the standards by controlling the heat input and interlayer temperature.
Copper and copper alloys have good electrical and thermal conductivity. For copper welding, we use gas welding, argon arc welding, etc. During the welding process, we pay attention to preventing oxidation and cracking to ensure that the product quality meets the customer's requirements.

- copper
- bronze
- white copper
The tensile strength of titanium and titanium alloys can reach 900MPa, they are corrosion-resistant and biocompatible. We use 99.999% high-purity argon gas double protection welding, which can be widely used in aviation, Marine and medical devices.
The density of aluminium and aluminium alloys is approximately 2.7g/cm³, featuring high thermal conductivity and corrosion resistance. During welding, the oxide film is difficult to melt and prone to deformation. We adopt special processes such as AC TIG welding, pulse MIG welding or friction stir welding (FSW), combined with high-purity argon gas protection, to break through the surface aluminum oxide layer and prevent porosity, ensuring that the weld strength reaches over 80% of the base material. It can meet the demands of the industry.
Zinc and zinc alloys are corrosion-resistant and have excellent casting properties. Their low melting point (about 420℃) and high volatility make them prone to porosity, spatter and zinc vapor during welding. We adopt low-temperature brazing, gas shielded welding (MIG/TIG) or laser welding processes, and strictly control heat input to avoid material burning loss, which can ensure the density of the weld seam and guarantee product quality.

Frequent Asked Questions
TIG welding service uses the arc generated between the tungsten electrode and the workpiece as a heat source, under the protection of inert gases (such as argon, helium, etc.), so that the welded metal is melted and connected. Tungsten electrodes do not melt in the welding process, only play a conductive and arc role.
MIG welding service is a method of using a meltable wire as an electrode, using the burning arc between the continuous wire and the welder as a heat source to melt the wire and the base metal, and welding under the protection of an inert gas (such as argon, helium or its mixture).
Arc welding is a fusion welding method that uses an electric arc as the heat source. It converts electrical energy into thermal energy through the electric arc generated between the electrode (welding rod or welding wire) and the workpiece, melting the welding area of the welding rod (or welding wire) and the workpiece to form a molten pool. After cooling, a firm welding joint is formed. Arc welding is one of the most commonly used welding methods in modern industry, featuring flexible operation, strong adaptability and high welding efficiency.
Cold welding is a type of welding method carried out at room temperature or near room temperature, without the need for additional heating.
It relies on pressing two clean metal surfaces together under high pressure, making them contact particularly closely. From the atomic level, the atoms on the metal surface interact with each other and then form bonds similar to those between atoms in solid metals, so that we can create a strong weld seam.
Fusion welding refers to a method in which the welding joint is heated to a molten state during the welding process and the welding is completed without applying pressure.
Our fusion welding mainly includes the following welding methods: 1. Electrode arc welding 2. Submerged arc welding 3. Gas shielded welding 4. Plasma arc welding 5. Electroslag welding 6. Laser welding, etc. According to your production needs, we can provide customized welding process solutions to help customers reduce production costs and improve production efficiency!
