Chromium-zirconium copper (CuCrZr) is the most commonly used electrode material for IF spot welding machine, which is determined by its excellent chemical and physical properties and good cost performance. Electrode is also a consumable, and as the solder joint increases, it will gradually form a medium on its surface. How to solve this problem?
1. Uneven surface or welding slag of electrode head of spot welding machine: it is suggested to polish the electrode head with fine abrasive paper or pneumatic grinder to ensure the cleanness and flatness of electrode head.
2. Short preloading time or large welding current: it is suggested to increase preloading time and appropriately reduce welding current.
3. Burrs or oil stains on the product surface: It is recommended to use a file or shot blasting machine to grind the workpiece to ensure that the product surface is clean.
4. There is oxide layer on the surface of aluminum plate: it is recommended to polish the product with fine sand paper, remove the oxide layer on the surface of aluminum plate and then weld.
