Q&A

The upper and lower electrodes are pressed against the workpiece, creating a certain resistance under pressure, and the welding current through the workpiece, the welding current is passed through the wrokpiece to generate heat energy, which causes the two workpieces to reach the same melting point and welding, then pressurized and close-fitting, finally forming resistance welding.

The principle of double-sided, two-point overcurrent welding is adopted.
When welding the workpiece, the upper and lower electrodes are pressed against the workpiece, creating a certain contact resistance under pressure.
The welding current creates an instantaneous thermal welding and circuit at the two contact resistance points, without affecting the internal structure of the welding workpiece.
