Question (1): To qualify a groove-weld procedure to cover welding a base metal range 3/16 in. to 8 in. and deposited weld metal thickness range up to 8 in., is it permissible to weld a single partial penetration groove ¾ in. deep on a single piece of 1½ in. thick plate?
Reply (1): Yes.
Question (2): Within the limits stated in QW-451, does a partial penetration groove procedure qualify for welding a full penetration groove and vice versa?

可以覆盖。母材厚度能覆盖，焊缝厚度能覆盖就可以了。明确条文应该没有。

QW202.2(b)  Qualification for Partial Penetration Groove Welds. Partial penetration groove welds shall be qualified in accordance
with the requirements of QW-451 for both base metal and deposited weld metal thickness, except there need be no upper limit on the base metal thickness provided qualification was made on base metal having a thickness of 11/2 in. (38 mm) or more.
