Sep 13, 2017 · In a fabrication industry, it is not uncommon to see welding steel pipe with a stainless steel pipe. There are two very important factors that determine the success of welding dissimilar materials. The first important factor is the strict adherence to the designated welding procedures. The slightest of deviations can lead to some major problems.Welding Stainless Steel Tube and Pipe: Maintaining stainless steel pipe welding proceduresJan 22, 2013 · TIG welding is traditionally used for welding stainless steel tube and pipe, and remains the optimal solution for extremely high purity applications on tube or pipe at or below 6-inch diameter and schedule 10 wall thickness. The preferred method Welding 300-series pipe without back purgingWelding stainless steel tubes and pipes typically requires back purging with argon gas when using traditional processes, such as gas tungsten arc welding (GTAW) and shielded metal arc welding (SMAW). But the cost of the gas and the setup time for the purging process can be significant, especially as the pipe diameters and lengths increase.

I can't find much "down and dirty" information about proper weld preparation and argon purging technique.New Regulated Metal Deposition (RMD) MIG Welding Mar 01, 2008 · The techniques for welding carbon steel pipe are the same as those described here for welding stainless; however, to qualify procedures for welding 300 series stainless steel pipe without backing gas, fabricators must do the following: 1. Ensure a minimum 1/8-in. gap around the entire circumference of the joint.How to Weld - TIG Welding : 11 Steps (with Pictures stainless steel pipe welding proceduresTo weld steel, the electrode travels first down the weld line, and the rod chases after, "following" the heat. Add Tip Ask Question Comment Download. Step 11: Types of Welds. Getting the knack of TIG welding is mostly in getting the weld pool to form, at the same time, on both pieces of metal.
Sep 20, 2020 · The process of MIG welding stainless steel basically requires you to continuously feed a solid electrode wire inside the weld pool along with some shielding gas in order to protect the weld from all sorts of contamination. Besides, this process is quite simple and easy to do than TIG welding.Duplex Duplex stainless DUPLEX steel welding.
