With the application of precision resistance welding, it is always a problem to accurately locate the nut on the workpiece. The metal solution is imperfect, and now there are high-strength ceramic positioning pins (pins) that can overcome this problem.
The KCF positioning pin commonly used in China, when the insulation layer of the skin is worn away, the insulation becomes uninsulated, and it will shunt the current to the lower electrode. In this way, the originally set welding parameters will be invalid, and the welded products will have unstable bonding strength and it is difficult to find. For mass production of welding nuts, it is difficult to control the quality of welding strength. This is when the welding nut falls off when it is used. Or the main reason for not meeting the torque requirements.
