The invention also utilizes the advantage of rapid heating of high-frequency welding and the skin effect and proximity effect of high-frequency current to perform composite welding on the plate. The skin effect of the high-frequency current enables the high-frequency alternating current to flow in a shallow depth on the surface of the conductor in a concentrated mode, and the skin effect is more obvious along with the increase of the current frequency. Proximity effects of high frequency current the proximity effects can be used to control the location and extent of the weldment weld so that the current can be highly concentrated at the weld area.
