Self aligned boiler welding roller process and composition requirements

- Jul 05, 2019-

The self aligned boiler welding roller is a commonly used welding auxiliary device, which is widely used in the welding production process. In the working process, the friction between the welding piece and the active roller is mainly used to drive the cylindrical welding piece to rotate. In combination with a welding machine, a welding positioner, etc., automatic welding of the inner and outer ring seams, the fillet welds and the inner and outer longitudinal joints of the weldment can be realized.


Self-tuning welding roller frames are characterized by the application of pressure during the welding process without the addition of filler material. Most pressure welding methods, such as diffusion welding, high-frequency welding, cold-welding, etc., do not have a melting process, so there is no problem of burning of beneficial alloying elements like welding, and the intrusion of harmful elements into the weld. The welding of the roller frame simplifies the welding. The process also improves the safety and hygiene of the weld. 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 self-tuning 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 seams. 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. The welding roller frame can also be used with manual welding or as a device for detecting and assembling cylindrical workpieces.
