HWASHI Car Shock Absorbers Repair Machine, Resistance Seam Welding Machine
Seam welding machine is a method that uses a pair of roller electrodes instead of the cylindrical electrodes of spot welding, and the welded workpiece moves between the rollers to produce a sealed weld with a molten core overlapping each other to weld the workpiece together. The weld consists of a single weld joint, which is divided into roll spot welding or gas-tight seam welding according to the different core fusion overlap. Seam welding machine is widely used for thin plate welding of oil drums, tanks, radiators, aircraft and automobile fuel tanks and sealed containers in jet engines, rockets and missiles.

Features of The Seam Welding Machine
1. seam welding machine use the roller electrode to replace the cylindrical electrode of spot welding. 2. It will generate weld nuggets which will overlap with each other so as to achieve welding effect. 3. AC pulse current or amplitude modulation current will be adopted, but three (single)-phase rectification, medium frequency and high frequency DC are also available. 4. According to different overlap of the melting cores, it could be divided into roll spot welding and air-tight seam welding. 5. There exist three stages in the forming process of welding spots: pressurization, heating fusing and cooling crystallization like spot welding.
6. The welding wheel can be operated in both horizontal and vertical directions. 7. The transformer and the welding wheel adopt the forced water cooling circulation system, which has a high load duration and achieves Continuous and stable welding.
