Four stainless steel tube welding methods

Update:2019-06-11   View(s):79   Keywords :stainless steel tube, ss tube, 304,316 stainless steel pipes   
The welding of stainless steel pipes usually consists of several parts: bottom welding, filler welding and cover welding. Stainless steel pipe bottom welding is the most important part of stainless steel pipe welding. It is not only related to the quality of the project, but also related to the progress of the project. At present, the stainless steel base is divided into two processes: back-filled argon and non-filled argon. The back argon protection is divided into two types: solid core wire + TIG process and solid core wire + TIG + water-soluble paper process; the back is not filled with argon protection and is divided into flux cored wire primer and welding rod (drug wire) TIG welding.

Stainless steel primer welding usually adopts TIG process. According to the actual situation on site, we can use the following four methods for bottom welding.

1. The method of blocking ventilation protection by using a blocking plate on the back side;
2. methods for blocking ventilation protection by using soluble paper or using a combination of soluble paper and blocking board;
3. using flux cored wire to make TIG welding.
4. TIG welding is performed with a coating wire (self-shielded welding wire).
