Description

Technical Field

[0001] The utility model relates to the technical field of welding processing, in particular to a metal component welding bracket. Background Art

[0002] At present, metal parts need to be supported by welding brackets during welding. However, most of the current welding brackets have relatively single functions. When welding flanges and pipe fittings, the flanges are generally fixed on the brackets, and then the pipe fittings are placed on the flanges and fixed by pressing the top of the pipe fittings. In addition, the brackets are mostly fixed. Since the weld seams of flanges and pipe fittings are circular, manual welding is required to hold the welding gun around the weld seam. This is time-consuming and labor-intensive. The positioning accuracy of flanges and pipe fittings is generally poor. In addition, if the pipe fittings are high, the pressing and fixing operation is inconvenient. Summary of the Invention
