Certification methods for welding inspectors Codes and

standards for welding inspection

Objectives : At the end of this lesson you shall be able to
• describe the certificate method inspection code and standards
• explain the inspectors standard test.

Introduction: The purpose of welding inspection is to determine if a weldment meets the acceptance requirements
of a code, standard or other document. The welding Inspector must be familiar with welding processes, welding
procedures, welder qualification, materials, non-destructive and destructive testing of welds, be able to read
drawings, prepare and keep records, prepare and make reports and make responsible judgements and decisions.
IIW India’s National Welding Inspectors Certification Scheme (NWICS) is a comprehensive scheme which
provides for examination and certification of personnel seeking to demonstrate their competence and knowledge
in the field of welding inspection. The scheme is managed by the Governing Board of IIW India’s Authorised
Nominated Body (ANB-India) for personnel education, qualification and certification. IIW India is in the process
of transferring accreditation from NABET to NABCB (both divisions of QCI) as a conformity assessment body
(CAB) as per ISO/IEC: 17024-2012 for certification of personnel. IIW India’s ANB understands the importance
of impartiality, managing conflict of interest, ensuring security and confidentiality in all its activities in accordance
with ISO/IEC: 17024.
Scope of certification: This specification establishes the requirements for the IIW India-ANB Division to certify
welding inspectors, supervisors, engineers, quality control co-ordinators and examiners with respect to his / her
competency in carrying out welding inspection functions in fabrication and construction industry covering the
following:

1 Working safety
2 Review & preparation of required documentation
3 Inspection of weld joints before, during and after welding
4 Evaluation and acceptance of weld joints based on Destructive & Non-Destructive test results/reports

Levels of Certification: IIW India’s NWICS program provides for 3 (three) levels of certification
1 Basic level (NWIC - Basic)
2 Standard level (NWIC - Standard)
3 Advanced level (NWIC - Advanced)
Role and functions of Welding Inspectors: The candidate should be able to carry out the following activities at
different levels of certification.
1 Welding Inspector - Basic level
2 To independently carry out before, during and post-weld visual inspection and dimensional checks of weldments
against specification requirements and drawings.
3 To carry out the following functions under the supervision of a Welding Inspector – Standard level or Welding
Inspector - Advanced level
• Understand the application of various standards, codes, specifications, welding symbols, drawings, WPS
and statutory/regulatory requirements.
• Verify the compliance of raw materials & consumables, certificates against the applicable standards, codes
& specifications.

• Verify that joint dimensions, edge preparation, fit up, welding equipment and weld preparations are in
accordance with the drawings, standards and process requirements.
• Verify the compliance of pre-heat procedures against the applicable standards.

• To carry out in-process surveillance during welding to verify compliance with specified procedure including
pre-heat, welding parameters, inter-pass temperature control and any post-heat requirements.
