The 5-mm-deep weld face was vertical in the first test and rolling in the second, simulating the devel-oped edge of an oblique cut through a pipe. Grooves were at a constant 30 deg relative to the weld root face angle. In each test, the bottom pass was cut first, then the center pass, and finally the top pass to minimize the effect of previous ... Retrieve Here
