hello folks. I recently started working at a brewery with a lot of
302 stainless steel. My job is general brewery stuff but since I have experience TIG welding steel bicycle frames the brew master would like me to weld some stuff for him. I'm looking for any info related to TIG welding 302 stainless steel. I've gathered so far ER308 or ER312 filler rod and argon coverage on both sides of the weld. a kick in the right direction or any more info would be greatly appreciated. also, what happens if I wouldn't purge the inside of a stainless tube when welding? I'm thinking of stuff like handrails where only the outside sees any duty.thanks, dave
