Product Introduction:

Roll welding machine is a machine used for roll welding. Roll welding, also known as circular seam welding, is a method of using a pair of roller electrodes instead of cylindrical electrodes for spot welding. The welded workpiece moves between the roller plates, creating a sealed weld seam with overlapping fusion nuclei to weld the workpiece together. Generally, AC pulse current or amplitude modulation current can be used, and three-phase (single phase) rectification, intermediate frequency, and high-frequency DC current can also be used. Roll welding is widely used in thin plate welding of sealed containers in oil drums, cans, radiator, aircraft and automobile fuel tanks, rockets and missiles. The general welding thickness is within 3mm of the single plate.
Main features:
The weld seam of roll welding consists of one welding point, which can be divided into roll spot welding or airtight seam welding according to different core melting overlaps. The formation process of each solder joint, like spot welding, involves three stages: pressurization, heating melting, and cooling crystallization, but there are significant differences from spot welding. Due to the inevitable phenomenon of shunt, the distribution of current and thermal fields in the welding area has its own characteristics; The rolling disc that transmits pressure and is heated by electricity continuously rotates to change the welding position, so that the distribution of current and heat fields, as well as the crystallization characteristics of the melting zone, are all related to the speed of changing the position.
