Copper Tube and Aluminum Butt Welding Machine for Evaporator Body and Straight Pipe Welding
1. The resistance welding machine is used for welding the evaporator body and straight pipes. The complete equipment mainly consists of welding fixtures, resistance welding control systems, and transformers.
2. Welding method: resistance welding;
3. Workpiece material: copper aluminum;
4. Requirements for the workpiece to be welded: There should be no large amount of oil stains, rust or other debris, and the consistency of the workpiece to be welded should meet the requirements of automatic welding;
5. This machine uses the method of keeping the workpiece stationary and moving the mold for welding;
