Welder certification in India rests on a welder qualification test: the welder welds a test coupon under witness, and the coupon is tested to the code the project names. TCR Engineering tests these coupons at its Mahape laboratory in Navi Mumbai, where ASME Section IX and API 1104 bend, tensile and macro tests are on NABL certificate NABLT0726MH18640.
- Codes: ASME Section IX, API 1104, AWS D1.1, IS 7318 and EN ISO 9606, as the project specification names
- Coupon tests on the NABL scope: bend, tensile, macro, nick break and fracture tests to ASME Section IX and API 1104
- Witness: CSWIP and AWS CWI certified welding inspectors
- Laboratory: Mahape, Navi Mumbai; registered office at Lower Parel, Mumbai
Finding reliable welder qualification testing services Mumbai can feel like searching for a needle in a haystack.
Project teams across the Mumbai region know the problem well.
This guide sets out what TCR has learned working with welders across Mumbai's industrial sector.
The Brutal Truth: Where Welding Projects Go Wrong
Here is the risk that matters.
Large projects have collapsed because someone cut corners on welder qualification.
The client thought they were saving money on testing.
They ended up paying for extensive rework.
The reality is harsh:
- Many welding failures trace back to unqualified welders
- Insurers can question claims on work done by unqualified welders
- International projects demand ASME/NABL compliance
- One bad weld can shut down entire facilities
At TCR Engineering Services, we have handled the aftermath of these disasters too many times.

Frequently Asked Questions
How long does welder qualification testing take in Mumbai?
The schedule depends on the process and position requirements, and complex multi-process certifications take longer, including training time. It is confirmed in the quotation.
What is the validity period of welder qualification certificates?
ASME qualifications are valid for 6 months without welding, extendable with continuous welding documentation. API 1104 qualifications require requalification every 6 months unless specific conditions are met.
Can welders qualified in one standard work on projects requiring different standards?
No, each standard has specific requirements. A welder must be separately qualified for ASME, API, AWS, or other standards as required by the project specifications.
What happens if a welder fails qualification testing?
Failed tests require retraining and retesting. The specific deficiencies must be addressed through additional practice and instruction before attempting requalification.
Are Mumbai-based certifications accepted internationally?
Yes, provided they are conducted by NABL-accredited facilities following international standards like ASME, API, or AWS. Proper documentation and the ILAC mutual recognition arrangement, of which NABL is a signatory, support acceptance abroad.
How do basic and advanced welder qualifications differ?
Advanced qualifications such as 6GR pipeline welding involve more coupons, positions and examinations than basic structural qualifications, reflecting the complexity and critical nature of the applications.
Do we need separate qualifications for different materials?
Yes, qualification is material-specific. Carbon steel, stainless steel, and aluminium require separate certifications due to different metallurgical properties and welding parameters.
How do I verify a welder's qualification status?
Request original certificates, verify with the issuing authority, check validity dates, and confirm the qualification covers your specific requirements. TCR Engineering Services can assist with verification processes.
Can qualification testing be done at our facility?
Yes, TCR Engineering Services provides on-site welding qualification and inspection services. Our certified welding inspectors deploy with proper equipment including inspection mirrors, electrical measuring instruments, and temperature monitoring tools to check standards compliance.
What documentation should we maintain for qualified welders?
Maintain original certificates, continuity records, project-specific qualifications, requalification schedules, and performance records. TCR provides complete documentation including WPS, PQR, and electrode qualification records for compliance with the code the project names.
Does TCR Engineering Services provide electrode qualification testing?
Yes, TCR provides comprehensive electrode qualification testing including consumable performance verification, chemical composition analysis, and procedure qualification for electrode-base metal combinations as part of our complete welding procedure programme.
What does TCR Engineering Services offer for welder qualification in Mumbai?
TCR Engineering Services was founded in Mumbai in 1973. Its Mahape laboratory in Navi Mumbai holds NABL ISO/IEC 17025:2017 accreditation (certificate NABLT0726MH18640), the TCR group serves 6,500+ clients, and TCR provides complete welding procedure programmes including WPS preparation, PQR documentation, and on-site inspection services with certified welding inspectors.
How does a welder get certified in India?
In India a welder is certified by passing a welder qualification test to the code the project names, such as ASME Section IX, API 1104, AWS D1.1 or IS 7318. The coupon is welded under witness, tested in an accredited laboratory, and the range qualified is recorded on the welder performance qualification record.
Which tests are done on a welder qualification coupon?
The code names the tests. ASME Section IX calls for bend tests or radiography on a welder performance coupon, and API 1104 calls for nick break and bend tests, with tensile tests where the pipe size requires them. TCR Engineering runs these coupon tests at its Mahape laboratory on NABL certificate NABLT0726MH18640.
