Characteristics of welded roller frame

- Mar 13, 2018-

The characteristic of the welded roller frame is to apply pressure in the process of welding without filling material. Most welding processes such as diffusion welding, high frequency welding, cold welding, no melting process, and not as useful as alloying elements welded burning, and the harmful elements penetrated weld, welding roller which simplifies the welding process, but also improve the welding safety and health. At the same time, the heat affected zone is small because the heating temperature is lower than the fusion welding and the heating time is short. Many materials which are difficult to be welded by melting welding can often be welded into high quality joints with the same strength as the parent material by pressure welding.
