1. Corresponding selection of welding equipment, for example, if the thickness of the material is less than 1mm, the gas dioxide welding machine shall be selected, and the oxyacetylene equipment shall be selected if the thickness is less than 1mm

2. Strictly abide by the welding process flow, such as the matching of welding current or oxyacetylene flame, welding speed, weld specification design, welding strip transportation mode and the resistance of thermal internal stress of sheet metal components

3. Repair the overall appearance of components in the later stage, such as body size, secondary grinding of welds, etc
