🏭 Test Laboratory Required
📋 Welding Process Used As Per WPS
Actual values used during test welding (must be within WPS range):
⚗️ Mechanical Test Results QW-150
Lab test results that prove weld integrity. All values entered will appear in PQR PDF.
📏 Tensile Test PASS
QW-152: Reduced section tensile, failure must occur in base metal at ≥ specified UTS
| Specimen | Width (mm) | Thickness (mm) | Area (mm²) | Max Load (kN) | UTS (MPa) | Failure Location |
|---|---|---|---|---|---|---|
| TS-1 | ||||||
| TS-2 |
✓ Both specimens exceed minimum 515 MPa (SS316L). Failures in base metal indicates weld is stronger than base material.
🌀 Bend Test PASS
QW-160: 2 face bend + 2 root bend (or 4 side bend if T ≥ 10mm), 180° around mandrel
🔨 Hardness Survey PASS
Vickers HV10. Max 350 HV for SS, 320 HV for sour service per NACE MR0175
🔋 Charpy V-Notch Impact PASS
3 specimens each at weld metal & HAZ. Min energy depends on grade & temp.
| Location | Temp (°C) | Energy 1 (J) | Energy 2 (J) | Energy 3 (J) | Average (J) | Min Req (J) |
|---|---|---|---|---|---|---|
| Weld Metal | ||||||
| HAZ |
🔍 Macro / Micro Examination PASS
🧬 Additional Tests (if required)
📊 Pass-by-Pass Welding Sequence QW-409 detail
Each weld pass with current, voltage, speed, and calculated heat input. This is what auditors check.
| Pass | Process | Filler Size | Current (A) | Voltage (V) | Speed (mm/min) | Heat Input (kJ/mm) |
|---|---|---|---|---|---|---|
| Root | ||||||
| Hot Pass | ||||||
| Fill 1 | ||||||
| Fill 2 | ||||||
| Cap |
Heat Input formula: HI = (Volts × Amps × 60) / (Speed × 1000) kJ/mm. Multi-pass keeps each pass below interpass limit.
