What copper is suitable for spot welding machine contact?
General spot welding chromium, zirconium, copper, welding, galvanized, alumina, copper better.The double point welding current welding principle, when the two electrode pressure workpiece makes two layers of metal forming some contact resistance in the two electrode pressure, welding current from the electrode through another electrode is formed on the two point contact resistance moment of welding, and the welding current from another the two part flow along the electrode with the electrode to form a loop, and will not hurt by the internal structure of welders.
Commonly used materials for spot welding electrode have beryllium copper, chromium copper, tungsten copper, pure tungsten and molybdenum, and according to the requirements of welding workpiece of different materials, electrode materials and the corresponding collocation, can high quality welding joints. So, you first want to tell me, your product material is what, what kind of welding requirements, we can help you recommend the appropriate electrode material.
Take the main transformer of the 5KW household regulator, remove the movable contacts and other accessories. Separate the two layers inside and outside the coil. The inner layer doesn't need to be used. 2.5 with the same number of cotton round a layer, as the primary. Take the 2*9 flat copper wire around the 42 ring,
