A roll welding machine (seam welding machine) is used to create a permanent metal bond by pressing the workpiece between two rotating welding wheels; the wheels drive the workpiece while welding current heats it locally to form overlapping weld points and a continuous seam. It features a three-phase stepless speed-regulation electrode drive for convenient, stable welding speed control, with two operating modes (vertical and horizontal), and an internal design that helps reduce performance weaken
Suitable for seam welding of enclosures such as car/motorcycle fuel tanks and barrels such as steel drums, as well as formed sheet-metal components such as wheels, sound-absorbing fins, radiators, and similar parts. A seam welding machine typically comprises a frame, a pressure mechanism, a welding wheel (electrode), a welding power supply, a speed control transmission mechanism, and a controller.
