Belonging to a type of welding electrode, it is used for welding in resistance welding equipment, such as fixed spot welding machines, suspended spot welding machines, and robotic spot welding machines. Because it is mounted on the electrode connecting rod, it is called an electrode cap. The material is mostly chromium zirconium copper, and there are also dispersed copper. After welding a certain number of times (usually 1000-1200 points), if it needs to be repaired or replaced due to wear and tear, it belongs to welding consumables.
The material commonly used for electrode caps nowadays is chromium zirconium copper. Adding trace amounts of chromium and zirconium to pure copper can significantly improve its hardness and high-temperature softening temperature, with good electrical conductivity. There are also those that use dispersed copper, which is used for welding galvanized sheets, because if the electrode cap made of chromium zirconium copper material is used for welding, chromium will react chemically with zinc in the galvanized sheet, producing a substance similar to copper, which affects the quality of welding. And dispersed copper can better solve this problem.
