Spot Welding Machine Process
1. welding time: when welding mild steel, welding method of spot welding machine can be used to standardize (instantaneous power) or weak specification for welding process (when powered on) should be adopted in mass production specification for welding, it can increase productivity, reduce energy consumption and reduce the deformation of the workpiece.
2. welding current: welding current depends on the weld size, thickness and contact surfaces, metal conductivity usually high electrode force larger soldering time should be shorter, the required current density increases at this time.
3. Press: electrode on the welding pressure is designed to reduce the contact resistance of the welding spot and needed to ensure that solder joint formation pressure.
