Imperfection screening
Weld Quality Inspection Guide
Connect ISO 13919 quality levels with shop-floor inspection steps for visible weld outcomes, section checks, records, and process-window decisions.
First checkVisual + size
Measure bead width, surface defects, and obvious discontinuities.
Section checkCut + polish
Cross-sections confirm penetration, fusion, and HAZ shape.
DecisionAccept / adjust
Keep only settings that meet geometry and defect targets together.
Inspection sequence
| Step | Inspection action | Pass signal |
|---|---|---|
| Visual surface | Check top bead continuity, undercut, spatter, oxidation, cracks, and start/stop marks. | No open cracks; bead is continuous; surface defects match the project target. |
| Dimensional check | Measure bead width, reinforcement, penetration depth, and root condition. | Dimensions stay inside the drawing or trial target across repeated samples. |
| Cross-section | Cut at start, middle, and end for long seams or at representative spots for tabs. | Fusion line, porosity, and HAZ shape are consistent. |
| Record | Save photos, settings, material batch, fixture ID, and rejected parameter ranges. | A second operator can reproduce the accepted sample set from the record. |
