Order)Which is the best gas for stainless steel arc welding?Straight argon is recommended for gas tungsten arc welding (TIG) of stainless steel tube and pipe. Shielding gas selection for wire processes is more complicated. Traditionally, MIG welding has relied on mixtures of argon and carbon dioxide, argon and oxygen, and 3 gas mixtures based on helium, argon and carbon dioxide.See all results for this questionWhich is the best filler metal for stainless steel pipe?Selecting filler metal for stainless steel pipe is about enhancing the properties of the weld and meeting the requirements of the application. Filler metals with an L designation, such as ER308L, provide a lower maximum carbon content, which can help retain corrosion resistance in low carbon stainless alloys.See all results for this question

Welding stainless steel tube and pipe traditionally requires a back purge of argon. In non-critical applications, where cost is a driving factor, nitrogen can also be used as a back purge but it may lead to the formation of some nitride compounds in the weld root, which sacrifices some corrosion resistance.See all results for this questionWhat do you need to know about stainless steel pipe welding?Theres no voodoo when it comes to welding stainless steel tube and pipe proper selection of filler metals, joint preparation, cleanliness and welding processes help ensure that the final product meets the designated quality standards and retains its intended corrosion resistant qualities.See all results for this questionWelding Stainless Steel Tube and Pipe: Maintaining trade assurance best price thin wall 6 inch steel pipe Submerged arc weldingJan 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 for high purity food-grade stainless steel is an autogenous TIG square butt weld.
