Weld Inspection Analysis & Defect Documentation
Evaluate weld defects, classify non-conformances, and generate AWS-compliant inspection reports
What You Can Do
You can input visual observations of weld defects (porosity, cracks, undercut, spatter) along with dimensional measurements, and Claude will cross-reference them against AWS D1.1 acceptance criteria, determine accept/reject decisions with technical justification, and generate consistent, professionally formatted inspection reports. This skill augments your fieldwork by organizing observations, standardizing documentation, and reducing the time spent drafting non-conformance reports while maintaining compliance rigor.
Features
Categorizes observed surface defects (porosity, cracks, undercut, spatter, lack of fusion) using AWS D1.1 terminology and severity standards
Applies AWS D1.1 acceptance criteria to visual observations and measurements, providing clear justification for each decision
Structures rejection findings with defect location, size, type, and recommended disposition (accept, repair, reject)
Evaluates weld leg size, throat depth, and profile against specified tolerances and AWS standards
Produces formatted, professional reports summarizing weld ID, defects found, accept/reject status, and inspector comments
Cross-checks visual observations against specified weld procedures (filler metal, preheat, technique) for process conformance
Tracks recurring defect types across multiple welds to identify process issues or training gaps
Generates technical reasoning suitable for project documentation, dispute resolution, and safety audits
Example Output
Example 1: Porosity Rejection Report
Weld ID: W-107 (Column-to-Beam Connection, Level 3) Defect Type: Surface porosity Observation: 5 visible pores, largest 3/16" diameter, distributed across 2" of weld length AWS D1.1 Criterion: Max 3/16" diameter, max 3 pores per 6" length Decision: REJECT — Exceeds acceptance criteria for porosity frequency Recommendation: Grind and reweld affected area per WPS-042
Example 2: Undercut Acceptance Report
Weld ID: W-203 (Plate Splice, Lower Flange) Defect Type: Undercut at toe Measurement: 1/32" depth, 1" length AWS D1.1 Criterion: Max 1/32" depth for Category B welds Decision: ACCEPT — At maximum allowable limit; document as critical observation Inspector Note: Welding technique issue; advise operator on travel speed
Example 3: Multi-Defect Inspection Summary
Inspection Date: 2024-01-15 | Inspector: J. Smith | Project: Steel Frame Assembly
| Weld ID | Defect | Size | AWS Criterion | Decision |
|---|---|---|---|---|
| W-104 | Spatter | Minimal | Cosmetic | Accept |
| W-105 | Lack of Fusion | 1/4" | <1/8" max | Reject |
| W-106 | Porosity | 1/8" | <3/16" max | Accept |
