[0003] In the welding operation of parts processing, welding fixtures are required to increase the stability of workpiece placement and improve the welding effect between workpieces. Chinese invention with publication number CN217750124U discloses a welding fixture with a positioning calibration mechanism. The welding fixture adopts a split plug-in design, and the fixing column and support plate can be snapped into the welding shell to facilitate material loading and unloading and positioning.
