The root cause of the core offset of the mid-frequency spot welding machine is that the heat dissipation and heat dissipation of the two welds are not equal in the welding area during the heating process, and the offset direction naturally moves towards the side with more heat dissipation and slow heat dissipation.
When spot welding with different thicknesses, the resistance of thick parts has more heat out, and the heat out center is far away from the electrode and the heat dissipation is slow, and the thin part is the opposite, which causes the welding temperature field and the melting core to shift to the thick plate.
When different materials are spot welding, the resistance of the workpiece with poor conductivity is more than that of the workpiece, but the heat dissipation is slow, and the situation of the material with good conductivity is the opposite, which also causes the welding temperature field to shift to the workpiece with poor conductivity, and the shift of the temperature field brings about the corresponding shift of the melting core.
