What the UPS guy brought me

MoparMike1974 chimed in before me. I agree with him, having welded a lot of frames for cranes and truck mounts. By engineering design not all is to be welded, so item can flex. Before welding, I would contact them first. If for some reason something would fail and would lead back to the part being welded where it shouldn't, you would be at fault. We had that problem with people welding on cranes and boom sections where they shouldn't and it actually made the part more brittle.
