Description

Technical Field

[0001] The invention relates to the technical field of welding machine tools, in particular to a welding machine tool for assembling hardware products. Background Art

[0002] Welding is a manufacturing process and technology that uses heating, high temperature or high pressure to join metals or other thermoplastic materials such as plastics. Welding achieves the purpose of joining through the following three ways: fusion welding heats the workpieces to be joined to partially melt them to form a molten pool, which is then joined after the molten pool cools and solidifies. If necessary, molten fillers can be added to assist; pressure welding must apply pressure to the weldment during the welding process; brazing uses a metal material with a lower melting point than the parent material as a brazing material, and uses liquid brazing material to wet the parent material, fill the gap, and diffuse with the parent material to achieve a connection between the welds. There are many sources of energy for welding, including gas flame, arc, laser, electron beam, friction and ultrasonic waves.

[0003] At present, in the welding work of the sheet metal parts on both sides of the inner wall of the U-shaped steel, it is necessary to manually hold the sheet metal parts and then perform electric welding. The welding efficiency is slow and the assembly stability of the sheet metal parts cannot be guaranteed.
