The preferred method for high purity food-grade stainless steel is an autogenous TIG square butt weld.See all results for this questionWhat should I use to clean my welding pipe?Clean the inside and outside of the pipe to remove any contaminants. Use a wire brush designed for stainless steel to clean at least 1 in. back from the edge of the joint. Use a stainless steel filler metal with a high silicon content, such as a 316LSi or 308LSi. Higher silicon content helps the weld puddle wet out and acts as a deoxidizer.See all results for this question
