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 c spot welding, etc. d selects 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 is used for welding stainless steel plates and aluminum alloy plates. Robot welding can save construction time, improve efficiency and welding quality, and ease work intensity.

welding rods of different sizes, specifications and models shall be used according to the size of the parts, the thickness of the raw materials and the size specified by the laser cutting manufacturer.

welding marks for sheet metal processing: Δ fillet welding, Д welding, I welding, V welding, V welding on one side (V) and blunt edge V welding (V), spot welding (O), plug welding or slot welding, riveting and pressure welding (χ), blunt edge of V-shaped welding belt on one side (V), blunt head of U-shaped welding belt, blunt head of J-shaped welding belt, bottom sealing welding.
