Welding auxiliary device and welding method for welding rotator

- Jun 14, 2019-

The welding rotator is a commonly used welding auxiliary device, which is widely used in the welding production process. In the operation, the friction between the welding piece and the active roller is mainly used to drive the rotation of the cylindrical welding piece, and the welding operation machine The combination of welding positioner and the like can realize the automatic welding of the inner and outer ring seams, the fillet welds and the inner and outer longitudinal joints of the weldment.


The welding roller frame is characterized in that pressure is applied during welding without adding filler material. Most pressure welding methods such as diffusion welding, high frequency welding, cold welding, etc. have no melting process, and thus there is no beneficial alloying element like welding. Damage, and the intrusion of harmful elements into the weld, the welding of the roller frame simplifies the welding process and improves the safety and hygiene of the welding. At the same time, since the heating temperature is lower than the fusion welding and the heating time is short, the heat affected zone is small. Many materials that are difficult to weld by fusion welding can often be welded to a high quality joint of the same strength as the base material.


The welding roller frame is a welding auxiliary device, in particular, a welding roller frame, which is commonly used for welding inner and outer circumferential seams of cylindrical workpieces and internal and external longitudinal joints. Including the base, the active roller, the driven roller, the bracket, the transmission, the power unit drive and the like. The transmission drives the active roller, and the friction between the active roller and the cylindrical workpiece drives the workpiece to realize the displacement. The inner and outer annular seams of the workpiece and the horizontal position welding of the inner and outer longitudinal joints can be realized. The automatic welding equipment can realize automatic welding. It can greatly improve the quality of welds, reduce labor intensity and improve work efficiency.
