Thats the standard prep for the CWB certification here. In school we had to do that test in all 4 positions, including overhead.
The test is destructive, 4 coupons are cut across the welded area after the backing plate has been gouged off. 2 coupons were bent 180 degrees across the root of the weld and 2 were bent 180 degrees across the face of the weld. We were allowed 1/8" of imperfection in the weld for all four coupons. Basically one small imperfection between all 4 coupons. Also we had to mark where our stops and starts were because thats where they took the coupons from.
I had to do these tests for stick welding, Mig solid core and Mig flux core...all 4 positions each
then there was the ASME tests. two 3/8" plates, 30 degree bevel on each plate with a 1/16" land and a 1/16-1/8" gap and no backing plate. The root pass had to penetrate consistantly and pass a visual test...then it was destructively tested the same way as the other test, 2 across the root of the weld and 2 across the face. again, all 4 positions.
The tests i hated were the pipe tests, same basic prep as the ASME plates but there was one position I particularily hated...6G I bleieve. The pipe is at a 45 degree angle to the table and is 'fixed' so it cannot be turned. You get a bit of every position on that one.
