Weld quality and self-aligning of welding roller frame
The main feature of the welding roller frame during the operation is the application of pressure during the welding process without the addition of filler material. The welding roller frame simplifies the welding process and also improves the safety and hygienic conditions 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 transmission device of the welding roller frame drives the active roller. When it is used, the friction between the active roller and the cylindrical workpiece is used to drive the workpiece to realize the displacement, and the inner and outer annular seams of the workpiece and the inner and outer longitudinal joints can be realized. Horizontal position welding, automatic welding equipment can achieve automatic welding, which 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.
The welding roller frame can automatically adjust the swing angle of the wheel set according to the diameter of the workpiece. It can automatically adjust the core when it is used. When it is matched with the welding machine and the welding power source, the inner and outer longitudinal seams of the workpiece and the inner and outer ring seams can be realized. welding.
The welding roller frame has low transmission noise and stable workpiece rotation, and can realize the operations of welding, polishing, lining and assembly of the cylindrical cylinder. The rotation speed of the roller should be stable and uniform. No crawling is allowed. It must have overvoltage protection, self-protection function, fault display and storage function, automatic air switch short circuit protection, and preset parameters.www.ht-tube.com
