So Im going to college to get my degree in welding. Im taking an advanced tig class and the teacher asked for 1/8in tig weld on 1/8in material. So most my steel tig welding ive done before and for other teachers say a semi concave to flat weld is perfect as long as there is no under cut ect. My advanced tig welding teacher now want us to run a bead that is some convex to it. In order to do this you must run cooler and use alot more filler rod. How does everyone else fill a correct 1/8in mild steel weld should look? Many of my other welds were alot more consitant but barley had a concave to the weld. My teacher was finally happy when I welded it like this with some convex to the weld. How do you feel about concave vs convex mild steel tig welds?
