Products Details
The temperature during friction stir welding is relatively low, resulting in much smaller residual stress and deformation in the welded structure compared to fusion welding.
During the friction stir welding process, the heat input is lower than that of fusion welding, and no metal melting occurs at the joint. It is a solid-state welding process that preserves the metallurgical properties of the base material, making it suitable for welding metal matrix composites, rapidly solidified materials, and other materials that may exhibit adverse reactions under fusion welding.
Water-cooled or liquid-cooled plates produced by friction stir welding offer good flatness and reliable sealing. Due to the characteristics of the process, it is more suitable for manufacturing flat, simple-structure cold plates.
Vacuum brazing, on the other hand, can accommodate more complex structures, enabling cold plates to achieve higher heat exchange efficiency.
