ER70s3 is my go-to for solid wire. I wish my welder had enough power to run spray arc honestly. Hot, fast and furious, but I can lay some gorgeous beads with it. Recently I had to go electrode negative flux core to go fix a friend's tractor in central WA. I would've preferred to use 6010 rod on it but I don't have a buzzbox, just my Millermatic. Interesting that FCAW had such high failure rates. We didn't do RT or MT testing for our certifications, all we did was a visual and bend test. My test plates were flawless for that at least, so now I'm curious to see how they would've fared for RT and MT.
I come from a oil and gas/cryo/nuc background. Anytime I went into a code fab shop and they wanted to run FCAW I said that was fine but we were going to 100% RT on all welds and my company refused to pay for repairs or materials ..... they changed their tune FAST and went to solid wire without a debate and submitted new WPS' and PQR's.
Bend test depends on the radii bent. An API 2" bend test... Someone that takes their time with a oxy torch and bailing wire can pass it. ASME B31.1- 6G - 1/2" radius on .436" or a super coupon (.625") to test for all thicknesses is a different story. Bend test root and cap. Most think bending the cap is good enough, but it's what separates the field.
I still xray samples from time to time to make sure myself and my equipment are in order.
