PRECAUTIONS For preparing and cleaning base metal and weld beads, use cutting tools, hand tools, grinding wheels, and stainless steel wire brushes that are free of foreign material and that have not been used on low-melting metals (Zn, Sn, Pb, etc.), and alloys (brass, brazing alloys, solder, etc.) that contain these metals. Use suitable clean solvents that conform to job specifications. Do not use marking paint or crayon, temperature-indicating crayon, and cutting fluid containing sulfur. PREPARATION OF BASE METAL Produce the weld joint geometry shown in the applicable detail on Joint Welding Schedule and drawing. Before preparing a weld joint surface on arc-cut or oxygen-cut base metal, machine or grind to remove irregularities and 0.100 in. additional metal from the cut face. Remove burrs, laps, gouges, and other defects from shearing, sawing, etc. to produce smooth weld joint surfaces. Remove scale and oxide within 1 in. of each edge of the weld joint. Remove oil, moisture, chips, and other foreign material from weld joint and from base metal within 10 in. of each side of the joint. Heat treat to stress relieve severely cold worked base metal. Contact engineer if heat treatment procedure is not covered in job specification. Immediately before welding, inspect joint for foreign material by wiping with clean white cloth, damp with solvent. Reclean as required. ASSEMBLY AND FIXTURES Provide suitable fixtures to support and align parts during welding without excess restraint on the weld. Use welded-on temporary attachments only where necessary. Clean fixture within 10 in. of each side of weld joint. Set up parts as shown on Joint welding Schedule and drawing. Provide suitable baffles on root side of joint to confine and prevent contamination of the backing gas.

WSP- 1402 Revision 0 Date 8-13-68 Page 3

Tack weld by depositing short small beads equally spaced along joint. Remove oxide and defects. Grind tacks if necessary to produce tapered ends and flat or concave surface. Shield weld area to exclude moisture, foreign material, and drafts that contaminate inert gas shielding. WELDING POS ITION

All positions. WELDING PROCESS, CURRENT AND SCHEDULE Process:

Gas tungsten-arc.

Process Control: Manual. Current: Schedule:

Direct current, electrode negative (straight polarity). Follow Joint Welding Schedules in this Procedure.

WELD ING EQU IPMENT Current Source: Rectifier or generator having drooping volt-amp characteristic, and foot control to permit continuous control of welding current, and upslope and downslope of current over a 10-to-1 range. Arc Starter: High-frequency oscillator if available, ON during start only. Welding Torch: Hand-held gas tungsten-arc torch adaptable to the joint and suitable for amperage, electrode, and gas nozzle specified in Joint Welding Schedules. Electrode: Thoriated tungsten welding electrodes that conform to ASTM-B297, Classification EWTH-2. Flow Meters: Ar and He flow meters, as required, calibrated at specified flow rate. Gas Lines: Use metal or plastic. If necessary, backing gas lines may be latex rubber tubing in new condition. PEHEAT AND INTERPASS TEMPERATURE Preheat Temperature:

60째F (min), to 10 in. from weld joint.

Interpass Temperature: 200째F (max) .

WPS - 1402 Revision 0 Date 8-13-68 Page 5

Examine each weld bead and each crater for cracks, pin-holes, incomplete fusion, incomplete penetration, overlap, undercut, narrow grooves, tungsten inclusions, heavy oxide or scale, and other defects. Check that fillet size and butt weld reinforcement conform to job specification. Check that all beads have normal smooth surface and contour, and merge smoothly with each other and with base metal. Remove weld defects by grinding, filing, or machining. Before depositing each bead, examine weld groove and adjacent base metal for cracks, laminations, holes, and other defects. Report to Foreman defects in base metal and any other condition that might reduce weld quality. BACK-GROOV ING Before welding the second side of double-welded joints, machine or grind the back of the root to remove defects. POSTWELD HEAT TREATMENT Postweld heat treatment was not incorporated in procedure qualification. WELDER IDENTIFICATION Record welder identification for each weld. Do not die stamp base metal or weld. INSPECTION When the Welding Inspector believes inspection necessary, he will examine base metal or welds at any stage of fabrication; and when he has reason to question that this Procedure is being followed, the ability of the welder, or weld quality, he may require supplemental inspection, corrective action, or requalification of the welder.

AEWCT

During the fabrication and installation of the MSRE a number of commercial products were analyzed to determine what would be acceptable as cleaning agents, lubricants, insulation, threading and tapping compounds, etc., on INOR-8and stainless steel materials. A l l of these comercial items were analyzed for sulphur, since we have found sulphur to be extremely harmful to IKOR-~. It may be noted that most items were analyzed for low-melting metals and alloys which are also harmful to

INOR-8under certain condtions. This listing

is submitted with the

hope that it will be beneficial to other groups in the Laboratory.
