The butt welding of copper and copper alloy is better than that of aluminum alloy. The most commonly used ones are spot welding and butt welding. Resistors are generally used for butt welding.AC butt welding machine welding, and spot welding, thin copper parts are easy to spot weld, but thick parts are difficult to spot weld. Unlike aluminum alloys, thick plates cannot be welded with a medium frequency spot welder, but must be welded by resistance brazing or welding.
Let’s talk about spot welding first. Why is spot welding difficult? Copper alloy has good electrical and thermal conductivity, high resistivity, rapid heat generation and heat dissipation, and difficult plastic deformation.
Therefore, attention should be paid to spot welding copper alloy: 1. Thickness should be less than 1.5mm 2. Thin plates with a thickness of less than 0.2mm can be welded with a special foot-operated spot welder for copper strips. 3. 0.2~1.5mm is welded by pneumatic spot welding machine or medium frequency spot welding machine. 4. The electrode should be made of tungsten or molybdenum material 5. In order to prevent spatter and shunting, the spot distance and overlap amount should be increased during spot welding.
