This document defines the requirements for weld fittings and machine weldments using an orbiting welding head suitable for use on cold worked 3Al-2.5V titanium, 21Cr-6Ni-9Mn CRES and 718 nickel alloy tubing. Fitting standards covered by this specification include non-separable welded elbow, tee, and reducer fittings, and reconnectable 24 degree cone fittings such as sleeves and unions. The document has been revised to specify PRI-QPL, to clarify cleaning requirements, to change test references from MIL-H-5440 to AS18280, to include periodic control tests, and to make updates.
