Page 1 of 2

WPS No. GT-SM-5B(F43) Scope:

Manual GTAW & SMAW Welding of P5B (5 & 9 Cr, Mo) Steels 1/16 to 0.560 Inch Thick (Open Root or Metal Backing) Without Postweld Heat Treatment Using Inconel Filler Metal for ASME B31.3 Process Piping Applications Only Project: General Distribution Notch Toughness Qualified: No Issue Date: 11/13/2009 Abstracts: Format & Code Updates Revision No: 4 Supporting PQRs: ... GT-SM-5B(F43)-0.280 (Refer to drawings for weld sizes and additional joint details)

Joints (QW-402): 12

Joint Design: Single & Double-V, J or U Groove, Fillet & Socket Welds, Slot & Plug Welds, Seal Welds Metal Backing: Optional (See Notes) Alignment: +/- 1/16" or per Construction Drawings Nonmetalic / Nonfusing Backing or Retainers: Not Permitted Root Opening: w/o Backing: 1/16" - 3/16" … w/Backing: 1/8" - 1/4" Code Application: Restricted to ASME B31.3 Use Only Note 1:

Metal backing may be used when permitted by project specifications. Backing materials shall consist of the same P number as the base material. When using split-type backing rings in pipe, tack welding across the split is not permitted. Backing rings in pipe and tube shall be securely tacked on the upstream side of the joint to prevent dislodgement in service.

Base Metals (QW-403): P-No: 5B - Group No: 1 (Note 2) ... to ... P-No: 5B - Group No: 1 (Note 2) Base Metal Thickness Range, Groove: 1/16 - 0.560 in. Deposited Weld Metal Limit, Groove: GTAW: 0.280 in. … SMAW: 0.280 in. Fillets: Unlimited Pipe Diameter Range, Groove: Unlimited Note 2:

Fillets: Unlimited Fillets: Unlimited Max. Single Pass Thickness: 0.28 in.

Excludes grades 91, P91, T91, F91, WP91, FP91. This WPS applies only to B31.3 Process Piping applications where the engineer or project specification specifically requires the joining of 5% or 9% chromium alloys without heat treatment.

Filler Metals (QW-404): SFA Specification: GTAW: SFA-5.14 … SMAW: SFA-5.11 Product Form: GTAW: Solid Rod AWS Classification: GTAW: ERNiCr-3 (Inconel Filler Metal 82) … SMAW: ENiCrFe-3 (Inconel 182) Supplemental Filler / Alloying: Not Permitted F No: F-No.43 (Both) Analysis: UNS N06082 & W86182 Consumable Insert: Not Permitted Welding Positions (QW-405): Groove: All Positions Vertical Progression: Vertical Uphill

Remove oil, grease and other contaminants using approved solvents. Method of Backgouging: For double-welded joints, back-gouge to sound weld metal using mechanical or thermal methods before welding second side. Interpass Cleaning: Chip, file, grind and/or brush each layer as needed. Inspect and remove defects prior to depositing next pass. Final Cleaning: Chip and wire brush. Note 4:

Use an adequate amount of filler metal and avoid concave root deposits which could cause center-line cracking because of the thermal contraction characteristics of the Inconel fillet metal.
