6.6.3.2 Reuse. Except as specified in 6.6.4, unfused granular flux may be reused subject to the following conditions:
(a) Flux shall be collected from clean, dry work pieces. (b) Flux should be mixed with new flux.
6.6.4 Submerged-arc granular flux for welding high hardenable alloys.
6.6.4.1 Preparation for use. Prior to the start of any wedding operation, granular flux shall be heated to 250°F minimum and used while warm to the touch. Flux shall be heated in clean, uncoated metal containers. Requirements for flux for S-11A and S-11C materials shall be in accordance with MIL- STD-1689 or MIL-STD-1688 as applicable.
6.6.4.2 Reuse. Unfused granular flux may be reused subject to the following conditions:
(a) Flux shall be collected from clean, dry work pieces. (b) Flux should be mixed with approximately 50 percent new flux. (c) If flux is not warm to the touch, it shall be heated to 250°F minimum.
6.6.5 Titanium and titanium alloy electrodes. Bare spooled electrodes and bare rod electrodes shall be kept in their original sealed containers until used. To prevent contamination, wire and rod shall be handled only with clean fabric gloves except leather may be used in actual welding. Once mounted on the wire spool tub, the titanium wire shall be kept circled in a dust cover. The wire feed path shall be cleaned at least once daily to remove any accumulated chips or dirt in the guide tube, rollers, or torch. Manually fed win or rod shall be wiped with a clean solvent-soaked cloth before use and thereafter handled, only with clean gloves. Wire or rod shall always have 1 inch of filler length removed from the tip before reuse. Wire and rod not in use for an extended period shall after moving the contaminated stub end be placed in clean, dust-free containers. Prior to reuse. this wire or rod electrode shall be wipe-tested by drawing a clean, lint-free cloth, wet with solvent, along a 12-inch length of the electrode. A slight darkening or smudge on the cloth is acceptable but any evidence of foreign material coming off the electrode is cause for rejection until the wire is double-wipe with solvent, respooled, and passes the wipe test.
6.7 Production testing of S-51, S-52 and S-53 welds. See 40, in appendix A.
