What was that welding exercise/exam?

My instructor had me butt weld some tubing in a vertical as well as a
horizonal position. Then grind off the weld until flush with the surface
of the tubing. Then cut the tubing into strips across the weld
approximately 3/8" wide. Then clamp each strip in a vise about an inch
away from the weld and bend the tubing back and forth until it breaks. A
break outside of the weld is a passing grade. A very humbling experience
at the time.
