Stainless steel bellows welding

Stainless steel bellows welding

  Stainless steel bellows requires very high welding technology; if the welding technology is not mature, it may cause perforation, water leakage, rust and other problems in the bellows.

  Many people don't know how the stainless steel bellows is welded. Today, let our engineers specifically explain to you the use of high-frequency brazing technology to weld stainless steel bellows.

  Stainless steel welding can be divided into five steps:

  The first step: welding ring determination according to the product gap and penetration requirements, calculate the appropriate welding ring size.

  The third step: tooling positioning. According to the size of the product to be welded, a suitable positioning tooling is made. Suitable tooling is an important factor to ensure the consistency of product welding.

  The third step: cleaning the pipeline. Because the pipeline is of metal nature, some waste slag will be generated in the pipe due to oxidation, and some waste slag will affect the welding effect. Therefore, before using welding, we apply emery cloth or paper to grind off the waste slag in the pipe.

  The fourth step: master the welding time. Generally speaking, set the automatic welding parameters according to the diameter of the welding product to be welded.

  Step 5: Post-welding treatment After high-temperature welding, there will be a certain degree of oxidation, so cleaning is required, and different concentrations of cleaning agents are selected according to the degree of oxidation.

  For the brazing of stainless steel products, not only reliable welding equipment is required, but also a good understanding of the entire product process to be able to weld reliable products. As a leader in high-frequency brazing processes, we always pass unique process requirements to Meet the complex welding process requirements to improve the product process level. Compared with traditional flame-welded bellows, high-frequency welded stainless steel bellows can ensure better penetration, provide high product performance, and make product quality more reliable.
