Types of Welding Inspection
1. Pre-Welding
- Material & grade verification
- WPS approval
- Welder qualification
- Joint fit-up check
2. During Welding
- Welding parameters monitoring
- Root pass & inter-pass temperature
- Visual monitoring
3. Post-Welding
- Visual Inspection (VT)
- NDT: PT, MT, UT, RT
Common Standards
- ASME Sec V & IX
- AWS D1.1
- API 1104
