Customized Dissimilar material welding Manufacturers in China

Dissimilar material welding, as a special joining method, join two or more materials together to leverage the different advantages of multiple materials. 

Welding structures made of different materials can not only meet the different material requirements under different working conditions, but also save a lot of high-quality and valuable materials, reduce costs, and fully leverage the performance advantages of different materials. 

In recent years, dissimilar material welding have been widely used in industries such as machinery, power, and nuclear industries, and the welding of dissimilar materials has also received increasing attention.

Dissimilar material welding

Friction stir welding is a solid-state welding technique that can reduce defects such as porosity, shrinkage, macroscopic segregation, solidification cracks, inter-metallic compounds, and welding deformation. 

Fsw of dissimilar material welding is commonly used to connect different series of aluminum alloys, aluminum alloys with copper, low-carbon steel, stainless steel, and titanium alloys. 

The mechanical and thermoplastic properties of materials, welding speed, tool speed, tool shape, pin shape, and axial force play a major role in the quality of joints.

Aluminum alloy has the characteristics of low density, high specific strength, high impact resistance and corrosion resistance, and is widely used in aerospace, rail transit, automobile, petrochemical, bridge construction and other fields. 

Dissimilar aluminum alloys have differences in strength, corrosion resistance, conductivity, and weld ability, and are often used in different working conditions. 

The connection of dissimilar aluminum alloys is receiving increasing attention in the lightweight design of automobiles. 

Welding of steel/aluminum dissimilar materials, by fully leveraging the advantages of high-strength steel plates and aluminum alloys, achieves the goal of energy conservation and emission reduction while ensuring safety performance, and is widely used in the field of automotive lightweight.


AEE has always been closely focused on the needs of new energy vehicles, continuously breaking through the key software and hardware technologies of intelligent friction stir welding, and developing towards lightweight and green direction.
