Welding roller frame

Welding roller is characterized in the welding process of pressure without filling material. Most welding processes such as diffusion welding, high frequency welding, cold welding, no melting process, and therefore not as useful as alloying elements welded burning, and the harmful elements penetrated weld, welding roller frame so as to simplify the welding process, but also improve the welding safety and health conditions. At the same time as the heating temperature lower than welding, heating time is short, small heat affected zone and. Many are difficult to weld by fusion welding material, often can use pressure welding process joint and parent material and equal strength quality.
