The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0023] Example:

[0024] like Figures 1-5 As shown, a welding device for sheet metal processing includes a processing table 1, a workbench 2 fixedly installed on the top of the processing table 1, and a support 3 installed on the rear side of the top of the processing table 1. The support 3 is provided with a protective component 4 for protecting the face of the worker.

[0025] The protective component 4 includes a movable seat 43 disposed inside the bracket 3. A movable block 441 is rotatably disposed on the front side of the movable seat 43. A protective plate 44 is fixedly disposed on the front side of the movable block 441. A through hole is opened inside the protective plate 44, and the through hole penetrates the top and bottom of the protective plate 44. An observation piece is disposed at the top of the through hole. A worm gear 47 coaxial with the movable block 441 is rotatably disposed inside the movable seat 43. A worm 46 meshing with the worm gear 47 is rotatably disposed inside the movable seat 43. A first handwheel 48 coaxial with the worm 46 is rotatably disposed at the bottom of the movable seat 43.

[0026] When welding sheet metal is required, the position of the protective component 4 needs to be adjusted first. According to the worker's observation position, the angle of the protective plate 44 is adjusted. First, turn the first handwheel 48, which drives the worm gear 46 to rotate, which in turn drives the worm wheel 47 to rotate, which in turn drives the movable block 441 to rotate, which in turn drives the protective plate 44 to rotate, which in turn drives the observation piece to rotate, until the observation piece and the protective plate 44 rotate to the appropriate angle.
