Reply:That makes for a little light reading. Actually for an old time muscle car guy, such as my self, I don't remember ever reading them. Thanks I saved myself a copy and will read later (too late now).Miller thunderbolt 250Decastar 135ERecovering tool-o-holic ESAB OAI have been interested or involved in Electrical, Fire Alarm, Auto, Marine, Welding, Electronics ETC to name a just a few. So YES you can own too many tools.
Reply:And yet they will grant exceptions to use alternative welding processes provided you supply data that backs up your request.
Reply:Might be nice to add NASA and or SCCA regs as well. In addition to defining the rules, these regs also outline the design and construction principles that should be followed (or at least understood) even if you're not building to a class.Syncrowave 300Maxtron 450, S-52E, 30A

Reply:If you spend $35.00 at www.sfifoundation.com you can get a book for the chassis you want to build that has the type of tubing,sizes and how and where each tube should go. well worth the money.
Reply:SCCA references to AWS D1.1 for welding will hopefully be changing in the near future once AWS D10.17 is released, since D1.1 has absolutely no business being referenced in an automotive application!
