Spot welding department USES double double flow principle of welding work two electrode pressure makes the two layers of metal workpiece under the pressure of two electrodes formed certain contact resistance, and the welding current from the electrode through another electrode formed in the two point contact resistance moment of hot melt, and the welding current moment from another electrode along the two artifacts flow so they form a loop, and will not hurt the internal structure of the welding workpieces.
