    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.
