WELDER QUALIFICATION TESTS &IWE/IWT CONSULTING SERVICES

Establishing WPS, PQR, Certifying Welders to International Codes & Standards

WPS, Welder Qualification Tests | Bangalore, India


Welding is a special process for joining materials. Also, welding is the principal fabrication process. Further, just welding the two members is not enough, they should be able to serve intended life. It is also important to prove that a welding procedure WPS meets the quality standards. Above all, ensure that the welder has skills to produce consistently good quality, defect free welds. Therefore, qualification test for welders is vital in welding. Our welder certification services includes WPS, performance qualification to codes, such as ASME Section IX, AWS D1.1, D1.2, D17.1 and other BS EN ISO standards.

If you wish to prepare WPS, test the welds and certify welders in India, contact Trinity NDT Welding Centre today. Certainly, our welding engineers quickly serve from Bangalore across Delhi, Mumbai, Chennai, Kolkata, Pune and Hyderabad. Above all, the weld testing laboratory has X-ray testing, Ultrasonic UT and other NDT inspections to bring you fastest results. We also provide IWE, IWT and CSWIP 3.1 welding inspector services in India.


Welding Machine Calibration in Bangalore


Calibration checks the Welding machine consistency in giving right voltage and amperage. Therefore, it is important to calibrate welding machines. That is to say, ‘Trinity NDT – Welding Centre’ calibrates your welding equipment to standards. We advice to service and calibrate the welding machines before the welder qualification tests so that problems due to faulty welding machines are avoided. Ask our welding machine calibration team to know charges.

How to Get WPS, Welder Qualification Certificate

Important documents in the Welders qualification procedure WPS, PQR and WPQ

A ‘WPS’ is a document with listed welding variables for repeatedly producing sound quality weld joints. Most importantly, various welding codes, standards and specifications helps to prepare welding procedure specifications (WPS).

The procedure qualification record (PQR) is a document that consists of record of weld test results. A PQR is a document that records the actual values but not lists ranges as is with WPS. Finally, from recorded results in PQR, a WPS is prepared with ranges using the essential variables as per the welding code. In other words, it is important that welder should know both WPS and PQR. In conclusion, PQR is an office document and WPS is a shop floor document for the welders. Both are quite important in welding.

WPS welder certification to AWS, ASME and ISO


WPS is a vital document that explains how to weld during production. Also, WPS records all the parameters used while doing the welding. Therefore, AWS and ASME section IX and ISO codes mandates preparing WPS and issue welders qualification. Trinity NDT-Welding Centre provides welders performance certificate and prepare a new WPS, if there is a change in any essential parameters. WPS basically documents information such as base material grade, electrode selection, preheating, post heating(if any), voltage, amperage, welding speed, weld position, gases to be used(if any), gas flow and many other essential and nonessential variables.

If the welder follows the WPS, he could able to produce the best quality welds. In general, WPS documents with ranges of weld parameters so that the welder could able to produce good quality welds.

Brazing performance for Brazers in India


Definition: Brazing is an another joining process in which a molten filler material is used that has a liquidous temperature above 450ºC but lower than the solidus temperature of the parent materials.

‘Brazer’ is a skilled person who holds and manipulates the device for heating the brazing area by hand. Whereas, Brazing operator is the person who prepares the brazing joints and sets up Brazing equipment and thereby direct influence on the Brazed joint quality.

Brazing Qualifications (BPS)


Brazing Procedure Specification (BPS) is a document providing the designations or values of the required variables necessary to achieve consistent brazing. That is to say, Brazers needs certification and qualifications. Contact us for BPS for brazers and brazing operators.

Welders and Welding Operators Certification


Trinity NDT – Welding Center‘ is providing Welders and Brazer qualifications since 2001. In addition, WPS meets welding standards, codes and specifications. Also, our team on Welder Qualification tests, Brazers Qualification Test, have experts with decades of experience with leading welding and fabrication companies.

That is to say, we extend our welding services through IWE, IWT, AWS-CWI, CSWIP 3.1 Welding Inspectors. The welding engineers at Trinity NDT can work together with clients and their counterparts while establishing WPS.

Why Trinity NDT-Welding Centre to certify welders?


Because, we have over two decades of experience in preparing WPS as per ASME, AWS, ISO standards and codes. Also, offers welder certifications as per Aerospace standards. For example: AWS D17.1 is the specification for fusion welding of aerospace applications. We also have associated mechanical testing lab for weld coupons. And, NABL ISO17025 Nondestructive testing (NDT) Labs for X-ray radiography testing and other NDT tests in the same campus. Therefore, we assure delivering test results in shortest time at affordable prices.

Our welding engineers have IWE and IWT certifications from IIW. Also CSWIP 3.1 from TWI, UK. With over two decades of experience, our welding services have worldwide recognition. With strong expertise in welding, trust us for welding and brazing qualifications. Contact us today to certify your welders.

Charges for WPS and Welder Certification


We keep the cost of our WPS services lowest in industry. Consequently, our charges for WPS Welder qualification are economical and affordable. Of course, the cost will vary as per the welding code and other parameters. In other words, at first we collect information, quickly estimate and reply back with cost of welder certification.

Also, Trinity NDT – Welding Engineers have ability to hand hold the clients in validating WPS and train their welders as per welding codes. Then, test the welders and issue welders certificate. Do you want to know the charges for WPS, PQR, WPQ preparation? We are just phone call away from you.

Basic steps in Welding WPS or Brazing Procedure

  • Firstly, Plan for the welding
  • Then, collect the data pertaining weld quality requirements
  • Meanwhile, write a Welding procedure(PreWPS) for use in trial
  • After that, make a test weld under the supervision of welding inspector
  • Then, perform mechanical and NDT testing of weld coupon as per Welding code
  • Subsequently, evaluate the weld test results
  • Approve WPS for welding
  • Finally, Prepare the documents as per code. For example, WPS, PQR and WPQ


Note: After the weld testing, all inspection results collated, and assessed as per code

Why Welding and Brazing Procedure Test


  • Firstly, to give maximum confidence that the welds mechanical and metallurgical properties meets applicable code/specification.
  • Secondly, each welding procedure will show a range to which the procedure is approved (extent of approval)
  • Finally, If a customer queries the approval, evidence can be supplied to prove its validity
