Description

Technical Field

[0001] The utility model relates to the field of welding equipment, in particular to a butt welding machine. Background Art

[0002] Butt welding machines are also called current welding machines or resistance butt welding machines. By using the resistance between the contact surfaces of the two workpieces, a low voltage and high current are instantly passed through, causing the contact surfaces of the two butted metals to instantly heat up until they melt and fuse. Most existing butt welding machines require workers to hold the welded parts and then fix the welded parts at the weld to align them. They can only let go after the equipment fixes the welded parts. This fixing method makes it difficult to align the two welded parts accurately, resulting in poor welding results. In addition, existing butt welding machines do not have the function of grinding the welded parts. After welding, the welded parts need to be moved to the grinding equipment for grinding, which is more troublesome.
