Stainless steel corrugated pipe welding technology is divided into TIG welding (not melting polar degenerate gas tungsten arc welding) and MIG welding (melting degenerate gas) welding, and the difference lies in that material used in the process of welding, MIG wire, and the TIG welding torch is used tungsten electrode, in addition, there is not much difference.  

Clean the pipe because of the metal nature of the pipe, the pipe should be oxidized to produce some waste slag, and some waste slag will affect the welding effect. Therefore, when we use before welding, use emery cloth or paper, the waste slag inside the tube is ground off.

Internal pipe welding temperature should not be too high, too high will make material changes easy to rust, external pipe welding cooling measures, too high temperature will affect the internal pipe, so, good ventilation measures are very important.In addition to the welding technology, the two welding methods also need to use a mixture of gas as the medium, consisting of 90% argon and 20% carbon dioxide. It can be seen that stainless steel bellows welding depends on technology and careful.
