Welder qualified using SMAW and F4 ( E7016) Electrodes. Is he also qualified to weld with F5 Electrode to Stainless Steel ( Butt or Fillet Welds )? All I know When F5 group of elctrodes used for welder qualification , he only qualified for F5 & F1 ( SFA 5.5). I'm confused with QW-404-14( Essential Variable for Welding Consumable limitations and QW-420(Wide range of base material qualified to weld ) If he is qualified, in ref to which sect? Pls advise, Thanks
Nalla, QW 433 F4 with backing qualifies for F 1, 2, 3 & 4 with backing F 4 without backing qualifies for F 4 without backing and F 1, 2, 3 & 4 with backing Hope that helps, Regards, Shane
