Masonry screws called Titen from Simpson Strong-Tie are sometimes used for attaching a building sign to a brick wall. https://www.confast.com/products/tapcon-concretescrew.aspx
I just try to demonstrate how it’s really not that hard to run a good overhead stick welding bead. I end up screwing off during the welding process to show that welding overhead is mostly a head game that people play with themselves and it’s not really that hard to do. During the weld, I lift up my welding hood, switch hands, run in place, walk around, and just plain screwing around all while never sticking the rod. The end result is a weld that has one lousy spot and might not look the greatest but, I guarantee it will hold. https://weldwithavengeance.com/
