The following is a step-by-step guide to “Why Certify Your NDT Technicians”. WJMG provides training, consulting web-based exam preps and study guide programs and Level III services to companies that certify their NDT personnel. Welding codes and standards require NDT to be performed by qualified, trained and certified personnel.
The NDT procedures as described in the welding codes have been used for many years and provide reasonable assurances of weld integrity. Users of the code may consider each method capable of detecting all unacceptable weld discontinuities. Users who rely on the welding codes should be familiar with all the limitations of the NDT methods, particularly, the ability to detect and characterize planar discontinuities. The limitations of each method are described in the Employer’s Written Practice.
