Qualification and certification of weld inspectors

Qualification and Certification of Weld Inspectors

  • Qualification and Certification Committee of the AWS formed in 1973

  • AWS QC1 first published in 1975

    • More than 55,000 individuals have the requirements for certification as a weld inspector (as of 2007)

  • Committee divided into two freestanding committees in 1996

    • one devoted to qualification of inspectors

    • one to certification of inspectors


Qualification vs certification

Qualification vs. Certification

Definitions per AWS B5.1:

  • Qualification – Demonstrate training, skill, knowledge and experience required for personnel to perform the duties of a specific job or function typically demonstrated by passing a performance test

  • Certification – The act of determining, verifying, and attesting in writing to the qualification of personnel in accordance with specified requirements.


Qc1 standard for aws certification of welding inspectors

QC1 – Standard for AWS Certification of Welding Inspectors

  • Defines the requirements and program for the AWS to certify welding inspectors

  • Requires documentation of:

    • Experience

    • Satisfactory completion of an examination

      • Determines general knowledge of welding inspection and related technical areas – not a practical exam

    • Proof of visual acuity


Qc1 scope

QC1 – Scope

  • Establishes the requirements for AWS certification of welding inspection personnel: how personnel are certified, and principles of conduct and practice by which certification may be maintained

  • Meets or exceeds requirements of AWS B5.1

  • 3 levels of certification:

    • Senior Certified Welding Inspector (SCWI)

    • Certified Welding Inspector (CWI)

    • Certified Associate Welding Inspector (CAWI)


Levels of certification

Levels of Certification

Reference AWS B5.1 and QC1:

*Subtract 2 years for Associate’s Degree, 1 year for vocational school; Add years (varies) for 8th grade education or less


Qc1 b5 1 definitions

QC1, B5.1 – Definitions

  • Endorsement – Indication of an additional skill documented in writing and added to one’s certification credentials

  • Nondestructive examination – the act of determining the suitability of some material or component for its intended purpose using techniques that do not affect its serviceability

  • Quality assurance (QA) – all the planned and systematic activities implemented within the quality system, and demonstrated as needed, to provide adequate confidence that an entity will fulfill requirements for quality


Qc1 b5 1 definitions continued

QC1, B5.1 – Definitions, Continued

  • QA audit – Systematic and independent examination to determine whether quality activities and related results comply with planned arrangements and whether these arrangements are implemented effectively and are suitable to achieve objectives

  • QA surveillance – Continued monitoring and verification of the status of an entity and analysis of records to ensure that specified requirements are being fulfilled

  • Quality control (QC) – Operational techniques and activities that are used to fulfill requirements for quality


Functions of an scwi

Functions of an SCWI

  • Train, supervise, and evaluate WIs, CAWIs, and/or NDE personnel

  • Prepare inspection procedures

  • Review and interpret joining procedures

  • Conduct audits of vendors

  • Ensure that work performed and records maintained conform to the requirements of the applicable standards and other contract documents

  • Certify the qualification of welders to various codes and specifications

  • Develop safety procedures, QA plans, project plans, and training programs

  • Perform skills as listed in Table I of AWS B5.1


Functions of a cwi

Functions of a CWI

  • Ensure that work performed and records maintained conform to the requirements of the applicable standards and other contract documents

  • Supervise and train AWIs

  • Conduct audits of vendors

  • Perform skills as listed in Table I of AWS B5.1


Functions of a cawi

Functions of a CAWI

  • Perform inspections under the direct supervision (within visible and audible range) of a SCWI or CWI

  • SCWI or CWI responsible for certifying that welded assemblies conform to workmanship and acceptance criteria

  • Perform skills as listed in Table I of AWS B5.1


Scwi written examination requirements

SCWI Written Examination Requirements

  • Must pass 200 question exam with a minimum score of 72%

  • B5.1 specifies the breakdown of the types of questions to be asked

    • Minimum of 10% on NDE fundamentals techniques, and applicability (VT, PT, MT, RT, and UT)

    • Minimum of 5% on safety programs and procedures

  • May retake exam up to 2 times with one year of original test date


Cwi written examination requirements

CWI Written Examination Requirements

  • Must pass three separate parts on: 1) fundamentals, 2) practical application, and 3) code application, with a minimum score of 72% on each part

  • If achieve an overall composite score of 72%, but earn a score less than 72% on any particular part, the failed part(s) may be retaken

  • B5.1 again specifies the breakdown of the types of questions to be asked for each part of the exam

  • Applicant may specify the code to which they are to be tested
