does certification for stainless tube welding prequalify you for carbon steel also?
Reply:No.Precipitation hardening nickel chromium steels can qualifiy non precipitation nickel chromium steels(Stainless) only, not carbon steels.If you want to qualify for carbon steel, you could test with 4130(hardenable), which would qualify you for all the nonhardenabale steels below it.Last edited by shovelon; 06-23-2012 at 12:12 PM.Weld like a "WELDOR", not a wel-"DERR" MillerDynasty700DX,Dynasty350DX4ea,Dynasty200DX,Li ncolnSW200-2ea.,MillerMatic350P,MillerMatic200w/spoolgun,MKCobraMig260,Lincoln SP-170T,PlasmaCam/Hypertherm1250,HFProTig2ea,MigMax1ea. |
