Description

Technical Field

[0001] The utility model relates to the technical field of butt welding machines, in particular to a butt welding machine provided with a guide clamping structure. Background Art

[0002] The butt welding machine is a device used to weld metals. It was first used in the production of automobile bodies in the early 20th century. The specific time is to heat the metal to be welded to a molten state to form a weld pool, so that the metals to be welded are melted together. During welding, the metal to be welded melts under the action of the heat generated by the current passing through the electrodes, so that the melted points between the metals are cooled and connected together. However, when welding to extend some metal parts, the metals need to be superimposed so that the metals move in the same direction for welding. However, the existing butt welding machines are prone to offset when multiple pieces of metal are superimposed during welding, resulting in uneven welding. Secondly, due to the unfixed position during spot welding, it is very troublesome to find a fixed welding point during welding, and welding cannot be performed at fixed intervals.
