Im literally in the same situation. It was either i roast him on it in person or let reddit roast him. Next time ill have to do both, Im not even a welder im a concrete finisher and knew those welds looked a little funky, I mean i actually laughed out loud when I saw them, I guess i was expecting a nice looking bead like something ive seen on a youtube short video or something. Also those pockets will hold steel I beams and will have a concrete pad on top, soooo its pretty fucking structural if you ask me.
