This page on welding cert cost just click on pricehttps://www.aws.org/certification/de...-welding-steelIf you have license and you hiring welder you ask for a cert in your field of work. This came out of North Ridge Earthquake after they Xray and other types of testing, thousands of welds and found a lot failed 😳 DaveLast edited by smithdoor; 4 Hours Ago at 11:15 PM.

Reply:I can see stick passing as mostly good welders can use stick. I had welders that never used stick or fluxcore. Most could only use MIG & TIG.I read list of errors almost 30 years ago.The data I remembered was there lot of solid wire use and poorly trained welders. The license holders did do and test the welders and used the fast way to do welding and taking sort cuts.It was big list of errors I can see fluxcore being on list as I away had train my welders as the only used solid wire. FYI In the field I only used E7018 and E6011 for metal buildings. Shop work was E71T-1 w/CO2 or E7018 and E6011I have friend how has cert and he used for field work fluxcore. Dave

And, outside the actual weld failures, there were also design flaws in the moment connections.The manufacturers of the Flux Core wires re-formulated, and re-certified, the wires for seismic welds after this. I believe that they got away with murder on that one. They probably knew the damn stuff was no good, and who knows if it's any better now that it's been "re-certified".I know this is going to reignite some old arguments, but I've felt that 7018 is the only truly safe material for structural work. It's just that it's faster, and easier, to run wire with less training. For this reason, wire is here to stay. And it might actually be up to code now. We won't know until the next Northridge I guess.
