4G. pipe. A welding test position designation for a circumferential groove weld applied to a joint in pipe. with its axis approximately horizontal, in which the weld is made in the overhead welding positiot by rotating the pipe about its axis. Rotation may be cojjfluous or incremental. See Figure B 19(A).
4G. plate. A welding test position designation for a linear groove weld applied to a joint in which the weld is made in the overhead welding position. See Figure B 17(D).
SF, pipe. A welding test position designation for a circumferential fillet weld applied to a joint in pipe, with its axis approximately horizontal, in which the weld is made in the horizontal, vertical, and overhead welding positions. The pipe remains fixed until the welding of the joint is complete. Sec Figure B20(F).
5G. pipe. A welding test position designation for a circumferential groove weld applied to a joint in a pipe with its axis horizontal, in which the weld is made in the flat, vertical, and overhead welding positions. The pipe remains fixed until the welding of the joint is complete. See Figure B 19(C).
6F. pipe. A welding test position designation for a circumferential fillet weld applied to a joint in pipe, with its axis approximately 45° from horizontal, in which the weld is made in flat, vertical, and overhead welding positions. The pipe remains fixed until welding is complete. Sec Figure 820(G).
6G. pipe. A welding test position designation for a circumferential groove weld applied to a joint in pipe. with its axis approximately 45° from horizontal, in which the weld is made in the horizontal, vertical, and overhead welding positions. The pipe remains fixed until welding is complete. See Figure B 19(D).
6GR. pipe. A welding test position designation for a circumferential groove weld applied to a joint in pipe, with its axis approximately 45° from horizontal, in which the weld is made in the horizontal, vertical, and overhead welding positions. A restriction ring is added, adjacent to the joint, to restrict access to the weld. The pipe remains fixed until welding is complete. See Figure 819(E).
A-Number. A designation for ferrous weld metal for procedure qualification based upon chemical composition1
abrasion soldering. A soldering process variation during which surface wetting is enhanced by abrading the faying surfaces.
abrasive blasting. A method of cleaning or surface roughening by a forcibly projected stream of abrasive particles. absorptive lens. A filter lens designed to attenuate the effects of transmitted and reflected light. See also filter plate. accelerating potential, electron beam welding and culling. The potential imparting velocity to the electrons. acceptable weld. A weld meeting the applicable requirements.
acceptance criteria. Limits placed on characteristics of an item as specified by the applicable standard.
