Study Notes
Visual Welding Inspection (VWI)
- VWI stands for Visual Welding Inspection, an integral part of quality assurance in welding processes.
- An effective visual welding inspection program can detect approximately 80% of weld discontinuities.
Standards and Specifications
- EN/ISO 17637 specifies requirements for visual inspection of welded constructions.
- This standard ensures that inspections are conducted consistently and meet quality standards globally.
Role and Verification
- VWI verifies the presence of weld quality attributes, such as surface finish and conformity to specifications.
- It checks for discontinuities, including cracks, porosity, and lack of fusion, ensuring welding integrity.
Basis of VWI
- The basis for effective VWI relies on established visual inspection criteria and guidelines.
- It emphasizes the importance of training and experience for inspectors to enhance detection capabilities.
