This type of rust can be caused by such external factors as carbon steel powders enerated by nearby grinding and brushing with carbon steel wire brushes, adhering to the surface of the stainless steel weld beads. Therefore, we guess that some carbon steel powders that had adhered to the surface of the DW-308 weld beads caused the rust in your case. 17 Causes of Porous TIG Welds and How How to deal with stainless steel pipe welding rust problem - Welding Contaminated Metal Gas Problems Electrode Problems Rod Contamination What else? The metal for the weld itself is the most common cause of contamination that leads to porous welds. Unlike other types of welding, TIG doesnt use any flux that can protect the weld from contaminated metal. That means all the metal has to be spotlessly clean before you crack an arc. If the metal isnt shiny, you wont get a good weld. There are several different contaminants that can cause weld probleSee more on weldingmastermind Can You Weld Stainless Steel To Mild Steel How to deal with stainless steel pipe welding rust problem - Welding How to deal with stainless steel pipe welding rust problemThe welded joint will be diluted with both metals. That is stainless steel and mild steel (each coming from both sides of the joint), and will eventually have the materials of both metals mixed. At the end of the process, you will have a weld deposit that has a chemistry that is compatible with what you have on both sides of the welded joint.

4 Ways to Prevent Stainless Steel from Rusting Tampa How to deal with stainless steel pipe welding rust problem
