Excuse me, how to weld 5mm stainless steel pipe? It is required to ensure the appearance after welding. thank you

5mm thick stainless steel pipe welding steps:

1, first smooth the butt joint, and the cross section is 90 degrees with the pipeline.

2. It is best to grind a 30-degree groove around the nozzle, leaving a blunt edge of1mm. After the two nozzles are butted, it is a 60-degree V-groove, which can ensure penetration and firm welding.

3. Choose the welding method. There are two options: one is bidirectional welding, which is faster. Then argon arc welding. You can choose this if the quantity is small. This is too slow. If the level is good, looks are not a problem.

4. When welding, align the two nozzles, leaving a gap of 0.5 mm-65438 0 mm ... If there is a high requirement on appearance, there are two ways, first base and then cover. The cover is very important, and the welding height and joint should be well controlled.

5. Appearance treatment, mainly polishing. Polishing is mainly done by polishing sheet. If the groove is welded, the cover surface can be kept flat with the pipe surface, and no welding trace can be seen after grinding. If there is no groove welding, there is an obvious weld bead.
