The continuous weld shall be straight and flat without significant non-flat, weld melting depth, weld inclination, weld mark, vent hole, undercut, etc. The welding viewing angle of the weld shall be as specified in the drawing, and the welding viewing angle shall not be guaranteed to be small thickness of adjacent parts.

knowing so many standards, I think everyone is very clear, but the characteristics of welding methods should also be mastered, so as to be more helpful in welding in sheet metal processing plants.
