Oh well, I was wrong. Mmmm, which Steve, that's the question.

S/S is not recommended but I know Mark uses it with a truck load of aerospace welders that have had no problems
I'm not saying that SS is
the only filler rod to use. I fully acknowledge that ER90/80 is the correct, by the book rod to use. I'm merely saying that it's worked for me and most of the aerospace welders I know without any problems whatsoever.
Back in the seventies I worked for a bloke named Ace Nofsinger who built midget race car chassis'. (
I was filling in operating a profile cutter for 6 weeks for a guy hurt in a race accident). Aces Mexican chassis guy was the first bloke I saw using staino filler rod on Chro-Mo and he actually taught me to TIG weld Chrome Moly. My previous experience was with brazing mild steel dragster chassis so it was extremely interesting to me.
A little while later I visited Ron Butlers chassis shop in LA. Ron, a Kiwi, had gone to America to build midget race car chassis but had graduated to building pro stock frames for some of the bigger teams (
The infamous Sox and Martin Hemi powered Dodge Colt (Galant here) was on the jig during my visit). I watched Ron welding the Galant's chassis and lo and behold, he also used staino filler too. Ron was originally an Air New Zealand sheety so perhaps the aerospace industry knows somethying the 'book' doesn't. I wonder why the Qantas guys almost to a man use SS? I share a few beers with some very good Pommy welders who work for Quantas but are subcontracted to the RAAF at Richmond and this subject has been a topic amongst us since it first came up last year.
Robert, you probably think I'm being disruptive here but that's not my intention. I'm merely offering another slant into the subject. If I wanted to be disruptive, my knee would come back into the thread
