Do any of you guys have experience TIG welding 8620? I want to do some minor (cosmetic) modifications to a cock cast in 8620.
A web search on the topic offered several good sites, including
http://www.windsorsteel.com/grades/8620-RD.htm. Apparently it is not easy to obtain a filler rod of 8620, so the rod to use is an issue. Experience with this anyone?
