您说的是UG-84(h)(3)和UG-84(h)(5)吧?原来只看了UG-84(g),没看(h)。好久不用冲击这部分内容,顾前不顾后,不记得要求了。确实如那位仁兄所言,焊缝和热影响区取样,要兼顾每一种方法。When qualifying a welding procedure with impact testing that employs multiple welding processes, or multiple sets of essential and supplementary essential variables for a
welding process, the welding procedure shall be qualified by testing separate sets of impact test specimens removed from the weld metal and heat-affected zone, as follows:
(-a) The requirements of (f) shall be met.
(-b) The requirements of (g) and (3) specifying the location, number, and orientation of test specimen sets to be removed for each welding process or set of variables
