|---|---|---|---|
| LOG. Welding Log — Column Definitions | |||
| COL-01 | S.No Acceptance: Sequential number starting from 1 for each welded joint entry; used for cross-referencing | Log entry sequence | |
| COL-02 | Date Acceptance: DD-MM-YYYY format; date when weld fully completed and cooled to handling temperature; not start date of welding | Welding execution date | |
| COL-03 | Joint ID Acceptance: Drawing-referenced joint ID (e.g., J-101, J-A2-15, etc.); must be unique within structure; links to structural drawing | Joint identification | |
| COL-04 | Drawing Ref Acceptance: Drawing number and revision (e.g., STD-001 Rev A) showing joint detail; links to weld schedule and specifications | Drawing documentation | |
| COL-05 | Location Acceptance: Description of location (e.g., 'Ground Floor, Column C-5 Base', 'Beam B-10 to Column C-7', 'North Face, Level 4', 'Footing to Pedestal'); enables field identification | Joint location on structure | |
| COL-06 | Joint Type Acceptance: Butt / Fillet / T-joint / Corner; must match drawing and WPS; determines inspection acceptance criteria and test requirements | Joint classification | |
| COL-07 | Weld Process Acceptance: SMAW (Shielded Metal Arc) / GMAW (Gas Metal Arc) / SAW (Submerged Arc) / FCAW (Flux Core Arc); must match WPS; process-specific quality criteria apply | Welding method | |
| COL-08 | Welder ID Acceptance: Welder's code/badge number or name; identifies who performed the weld; links to welder qualification certificate | Welder identification | |
| COL-09 | Welder Qualification Ref Acceptance: Certificate ID or reference (e.g., WELD-QIF-001, ASME D1.1-2015); confirms current qualification for process/position/material; valid period checked (typically 2-3 years) | Certification documentation | |
| COL-10 | WPS Ref Acceptance: WPS ID (e.g., WPS-STL-SMAW-001, WPS-STL-GMAW-002); confirms approved procedure for process/material/thickness/position; all welding done per approved WPS | Procedure specification | |
| COL-11 | Electrode Type & Size Acceptance: Classification and diameter (e.g., 'E7018 3.15 mm', 'SG2 1.2 mm wire', 'ER70S-2'); must match WPS; batch/lot number recorded for traceability | Filler metal specification | |
| COL-12 | Parent Metal — Grade & Thickness Acceptance: Grade (e.g., Fe 500D, E250) and thickness in mm; confirms material is suitable for welding process per WPS; links to material register | Base material documentation | |
| COL-13 | Weld Length (mm) Acceptance: Continuous weld length in mm as per drawing or job requirement; for fillet: theoretical length; for partial welds: actual length specified in drawing | Weld dimension | |
| COL-14 | Visual Inspection Result Acceptance: PASS if weld profile, size, undercut, porosity, cracks all acceptable per IS 816 Table 9; FAIL if any rejection criterion observed; HOLD if awaiting NDT | Visual examination outcome | |
| COL-15 | Visual Inspector Acceptance: Name or badge of visual inspector; establishes responsibility; typically site foreman or QC technician; certification required per project specs | Inspector identification | |
| COL-16 | NDT Required Acceptance: Y/N; 'Y' if drawing/project spec requires NDT (UT/RT/MPI/DPT); 'N' if visual-only acceptance permitted; percentage extent (e.g., 100%, 50%) noted in remarks if applicable | NDT decision | |
| COL-17 | NDT Type Acceptance: UT (Ultrasonic) / RT (Radiography) / MPI (Magnetic Particle) / DPT (Dye Penetrant); method selected per drawing, material, and joint accessibility | Non-destructive test method | |
| COL-18 | NDT Report Ref Acceptance: Report ID (e.g., UT-001-20260404, RT-002-20260404); links to detailed NDT findings and indications log; report filed with joint records | NDT documentation | |
| COL-19 | NDT Result Acceptance: PASS if no rejectable indications (cracks, large porosity, lack of fusion per IS 4260 / IS 1182); FAIL if rejectable defects found; PENDING if report awaited | NDT outcome | |
| COL-20 | Repair Required Acceptance: Y/N; 'Y' if visual or NDT failure requires repair; 'N' if joint accepted as-is; cross-reference to Repair Report if applicable | Defect disposition | |
| COL-21 | Repair Report Ref Acceptance: Repair report ID (e.g., REP-STL-001) if repair executed; includes defect description, repair WPS, re-inspection method and result; links to final acceptance | Repair documentation | |
| COL-22 | Final Status Acceptance: ACCEPTED if visual + dimensional + NDT all pass (or repair re-inspection passes); REJECTED if defects cannot be repaired or exceed concession limits; CONDITIONAL if subject to concession/waiver | Joint acceptance decision | |
| COL-23 | QC Engineer Acceptance: Name of QC Engineer approving joint; establishes responsibility for acceptance decision; must be authorized inspecting authority per project | QC approval authority | |
| COL-24 | Remarks Acceptance: Any deviations, special conditions, site constraints (e.g., 'Weather protected by tent', 'Field weld due to shop damage', 'Concession approved by PM on 03-04-2026', 'Repair completed 04-04-2026'); links to NCR or CAR if applicable | Additional notes | |
