Not sure you are correct about the structural shops 135fan. I owned a structural steel fabrication shop and have visited dozens of others, also I have read the spec book and bid on thousands of jobs, not one spec book I read said anything about mig welds not being qualified. All of them said 70 series wire or electrodes were needed. As said below, ER-70.... wire is qualified.
All our welders had up-to-date certificates and all welded "tickets" to be tested by local certification house. All the "tickets" were 1/2" plates, v'grooved with a 1/8" gap and welded up-hill, as necessary to be certified in all positions. Root pass is done with hard-wire and all other stringer passes done with 70 series flux-wire (outershield) WITH gas, 75/25.
Also, if a drawing called for full-penetration or large size fillet welds this was always done with with wire machines and 75/25 gas on multiple passes. Sometimes dozens of passes on one full-penetration weld.
The only reason we had a stick machine was if we had to weld a bunch of galvanized material we set up outside so the smoke wouldn't make everybody sick.
We use hard wire .035 (no flux) and gas on misc. steel, like stairs and handrail and light work and fluxwire .045 (outershield) and gas on heavy structural. Never had a weld fail.
That is just my experience here around the Louisville, KY area.
On the farm I have a gas engine Miller stick machine and I use 7018 rods for everything I make sure to clean everything as well as possible. Just not feasible to keep a wire feed welder on my farm.
