like dale said if it’s a mock up. A demo piece in which case what does it matter.
I know nothing about the item, what it does and what it’s done. What I do know is what a decent weld looks like from a defect inspection POV. I also have a firm understanding of typical criteria on welding defects and there allowances. Zero tolerance isn’t always practical so there are allowable tolerances on defects and craters on aluminium are typically a max depth with No limit on diameter last time I looked at a criteria spec on them which was for a company making scaffolding braces with tig.
Yes it’s quite a bit more tricky if you don’t have facilities to slope off. As you can’t control solidifying times. You would then need to do a patch up with low current re strikes and touching up with thin fillers. A bit more of a ball ache.
My 06 fireblade had Short weld on the swing arm that cracked 2/3 of the way across. It looked to of started from a small crater. In fairness with the rest of the design in the swing arm that weld could of failed completely and not caused any ill effect. I still re welded it mind. To me a crater shows laziness and laziness is something I’ve never really tolerated so the defect has a little grind on me when I see them because it’s like leaving something unfinished. Open box section on fabs pees me off in much the same way
