If looked at the welds in the basement of my 3700, I have 7 tig weld procedures- 16weld certs, have done 5 procedures for mig aluminum and countless certs, they all look like root passes, no precleaning visible, but there is no visible cold lap, havent found any cracks or welds pulling apart, I would take a gorilla weld or small root pass over a screw any day
