Welding around is then practiced by tacking and welding to a base sheet. For additional practice, it is
recommended that the inside of the pipe be weIded to the base plate. This aids in better manipulation
with the rod and the welder. From here, the welder proceeds to practice the conventional butt welds with
two sections of beveled pipe. Both sections should line up to a centerline. A flat on the bevel is essential.
The same technique applies for round-duct butt welding.
