Description

Technical Field

[0001] The utility model relates to the technical field of spot welding machines, in particular to a three-axis spot welding machine. Background Art

[0002] A spot welder is a device used to process metal parts. It mainly uses a high-temperature electric arc to partially melt metal parts to form a certain connection or connection. It is a very important equipment in the metal processing industry and is widely used in the connection, corrosion protection, and reinforcement of various metal materials. The spot welder adopts the principle of double-sided double-point overcurrent welding. When working, the two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode through the other electrode, an instantaneous heat weld is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the two workpieces to this electrode to form a loop, and will not damage the internal structure of the welded workpiece. However, the welding head of the existing spot welder is not convenient to replace during use, which makes the subsequent replacement more troublesome. Utility Model Content
