1. make welding according to the drawing, technology and laser processing technology regulations;

2. when welding, be sure to make grooves on the concave grooves.

3. When welding, the shape and position tolerance of the product workpiece should be guaranteed. Form and position tolerances for non-machined surfacing shall be in accordance with IT15 class.

4. if the raw materials must be replaced in the whole process of welding, the wall thickness of the plastic plate cannot meet the requirements of the drawings, and cannot be replaced without the permission of the written materials of the technical organization.

5. The weld seam during welding shall be strictly in accordance with the drawing regulations.

6. The continuous weld shall be straight and flat, without significant uneven, weld melting depth, weld inclination, weld marks, vent holes, undercut, etc. The welding angle of the weld shall comply with the provisions shown in the figure, and it is not necessary to ensure that the welding angle corresponds to the minimum thickness of the adjacent component.

7. after welding: solve each weld to carry out grinding and polishing, in order to remove the welding scar and eliminate the surrounding burrs.

8. Do not weld parts that must be bent on the drawing without the permission of the written material of the technical agency.

9. In the whole welding process of sheet metal parts, small and medium-sized manual hammers can be used to gently hammer the parts that must be knocked to the required specifications, and hammers are not allowed to knock on the plan of sheet metal 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 sheet metal processing and welding.

welding method for sheet metal processing: aCO2 gas shielded welding B argon arc welding machine c welding, etc. d select intelligent robot welding method according to specific needs and materials. Generally speaking, CO2 gas shielded welding is used for welding stainless steel plates; argon arc welding machine is used for welding stainless steel plates and aluminum alloy plates. Intelligent robot welding can save construction time, improve efficiency and welding quality, and ease work intensity.
