GMAW was really easy as far as the 3/16 inch weld joints because I got all the 3/16 inch weld joints signed-off for GMAW level I and level II. The best weld I did in GMAW was a 1/2 inch butt-joint vertical up using short-circuit transfer, this weld required a bend test and the weld succeeded in the bend test. I have pictures of the horizontal position 3/16 inch weld joints and a picture of the 1/2 inch vertical up position butt-joint.
