The welded roller frame of the roll welder is characterized by applying pressure during the welding process without filling the material. Most pressure welding methods, such as diffusion welding, high-frequency welding, cold-press welding, etc., there is no melt process, so there is no melt welding and other beneficial alloying elements, harmful elements invade the welding, welding roller frame simplifies the welding process, but also improves the safety and sanitary conditions of welding. At the same time, the heating temperature is lower than that of melt welding and the heating time is shorter, so the heat-affected area is smaller. Many materials that are difficult to weld can often be pressure welded into high quality joints with the same strength as the base material.
The welding roller frame is a welding aid, especially the welding roller frame, which is usually used for welding inner and outer joints and inner and outer longitudinal joints of cylinder workpieces. It includes base, active roller, driven roller, bracket, transmission device, and power unit drive. The transmission device drives the active roller and uses the friction between the active roller and the cylinder workpiece to drive the workpiece to rotate to achieve displacement, which can realize the inner and outer joints and horizontal position welding, and support automatic welding equipment can realize automatic welding, which can greatly improve the welding quality, reduce labor intensity and improve work efficiency.
Welding roller frame can also be used with manual welding or as equipment for testing and assembling cylindrical workpieces.
