<p>The invention relates to a spot welding head used for electronic industries, micro- electronic industries. The spot welding head is consisted of two parallel electrodes which are made of high temperature-resistant metals and joined together, and a insulating layer therebetween, wherein the insulating layer between two parallel electrodes is a insulating adhesive which act as a adhesive and a insulating spacer, thereby insulating rivets are omitted, further the tips of two parallel electrodes are ohmic contact each other. The welding head can weld enameled wires, bare wires, sheet metal and strip metal. The welding head is simple, reliable, its cost is low, and it can improve the welding quality and efficiency.</p> |
