Welder Certification & Procedure Qualification

TCR Arabia provides a comprehensive welder certification and welding procedure program that includes: 

  1. Welder Qualification Testing for performance qualification and certification of welders (a welder/welding operator performances qualification - WQT) to ASME, ANSI, AWS, API code

  2. Preparation for Weld Procedure Qualification that is relevant for either the project or any client requirements

  3. Coupon Testing as per Weld Procedure Qualification including visual examination, mechanical testing, metallographic examination and non-destructive testing

  4. Documentation of the Procedure Qualification Record as per ASME, ANSI, AWS, API codes

  5. Detailed weld inspection including the review of the qualification e.g. weld procedure specification, welder performance qualification, validity for process materials and consumable items, equipment, setup and other factors including certificates of calibration and/or conformity governing the task

  6. Ascertain safety of operations for the self, welder and other workers in the vicinity, particularly ultraviolet radiation from arc during welding


Welding Procedure Program

  • Check correct Weld Procedure(s) are employed

  • Review Weld Procedure and Welder Qualifications

  • Inspect Weld Profile Preparation

  • Inspect Joint Fit-Up

  • Check Filler Metals and Consumable Materials

  • Ensure Correct Welding Performance Parameters are Maintained

  • Perform Visual Examination Upon Completion Of Welding Monitor

  • Specified Pre and Post Weld Heat Treatment

  • Monitor the Physical Examination including Non-Destructive Test, Hydrostatic Test, and Mechanical Test Etc.

  • Based On the Requirement, the Inspector may Choose to send Test Samples to the TCR Engineering Services' Material Testing Laboratory

  • Verify all Necessary Visual Inspections are Completed and all other necessary Non-Destructive Examinations are Executed as Specified

Based on the requirements, the inspector may employ the following equipment to aid in the performance of duties:

  • Inspection Mirrors

  • Torch or other Electrical Lighting Facilities (permitted by safety codes eg. 24V system etc.)

  • Physical Size Measuring Instruments such as Welding Gauge, Rule, Vernier etc.

  • Electrical Parameter Measuring Instruments such as an Ammeter, Voltmeter etc.

  • Temperature Measuring Instruments (Thermometer)/Aids (Thermo Chalk)


All TCR Arabia welding inspectors are generally certified in accordance with the requirements of at least one or more of the following schemes:
