The welding roller frame uses the friction between the weldment and the active roller to drive the cylindrical (or conical) weldment to rotate. It is mainly used on a series of large machines in heavy industry.
The welding roller frame is a commonly used welding auxiliary device, which is widely used in the welding production process. Mainly rely on the friction between the weldment and the active roller to drive the rotation of the cylindrical weldment, combined with the welding manipulator, welding positioner, etc., can realize the automatic welding of the inner and outer circumferential seams, fillet welds and inner and outer longitudinal seams of the weldment.
The welding roller frame is characterized by applying pressure during the welding process without adding filler material. Most pressure welding methods such as diffusion welding, high frequency welding, cold pressure welding, etc. have no melting process, so there is no problem of beneficial alloy elements burning like fusion welding and harmful elements invading the weld. The welding roller frame simplifies the welding. The process also improves the welding safety and health conditions. At the same time, because the heating temperature is lower than that of fusion welding and the heating time is shorter, the heat affected zone is small. Many materials that are difficult to be welded by fusion welding can often be welded to a high-quality joint with the same strength as the base material.
Welding roller frame is a kind of welding auxiliary equipment, specifically a welding roller frame, which is often used for welding inner and outer circumferential seams and inner and outer longitudinal seams of cylindrical workpieces. It consists of a base, a driving roller, a driven roller, a bracket, a transmission device, and a power device drive. The transmission device drives the active roller, and uses the friction between the active roller and the cylindrical workpiece to drive the workpiece to rotate to achieve displacement, which can realize the horizontal position welding of the inner and outer circumferential seams of the workpiece and the inner and outer longitudinal seams. The automatic welding equipment can realize automatic welding , 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 testing and assembling cylindrical workpieces.
