Weld a piece of 12 inch pipe to another piece of 12 inch pipe in a 5G fixed position and a branch weld on a 12 inch piece of pipe to a 12 inch piece of pipe.
You may have to do this 2-3 times a month. And if you dont pass, the contractor does not pay you!
The 12 on 12 test butt and branch will take a hard 10 hours to get done. THat is prep, fitting, welding, cutting the straps and your turn at the iron horse.
