I have seen a few frames on bike pics on here and all the welds are the same I may well be sounding harsh but I don't mean to be like I said I'm critical because of my job and I wouldn't invest in something with not bad but moderate welding my job is mainly stainless 316l dairy bore pipe work with full penetration and then every weld is xrayed so the material thickness would not be a problem as its what I'm used to but if u come from a background welding thicker gauge steel I can defenatly see why it's harder
As always kind regards
