Four Welding Methods for Stainless Steel Pipe Engineering
Release date：2023/5/25 Reading times：819second
The welding of stainless steel pipe engineering usually consists of backing welding, filling welding, and cover welding. Stainless steel backing welding is the most critical part of stainless steel pipe welding, which not only relates to the quality of the project, but also to the progress of the project. Currently, stainless steel backing is divided into two processes: solid wire welding, TIG welding, and water-soluble paper welding, The protection without argon filling on the back can be divided into flux cored wire backing welding and flux coated wire backing welding.
Several methods used for backing welding in stainless steel engineering:
1. The method of using a blocking plate on the back for blocking and ventilation protection
2. The method of using only soluble paper or combining soluble paper and blocking board for blocking and ventilation protection
3. Using flux cored wire for backing TIG welding
4. Use coated welding wire (self-protection welding wire) for backing TIG welding.
When prefabricating stainless steel pipelines, the welded joints can usually be rotated for welding, making it very easy to ventilate. This is usually done by using a blocking plate to block and ventilate the two welded joints inside the pipeline for protection. At the same time, the outer side is sealed with adhesive cloth for backing welding.
