TRINITY NDT - CENTRE OF EXCELLENCE IN WELDING

Gigantic Infrastructure on Welding, Training, Certifying Welders & Welding Inspectors

Welding Procedure Specification (WPS), Procedure Qualification Record (PQR), Welding Operators Qualification, Welders Qualification and Certification Services at Trinity NDT, Bangalore India.

Welding is a modern manufacturing process that joins two or more materials. Just joining the two members is not enough to with stand the loads for longer duration. Hence it is essential to prove that a welding procedure meets the quality standards set forth and also to ensure the welder is capable of producing consistently good quality, defect fee welds.

A welding procedure is a systematic method that is used to repeatedly produce sound quality weld joints. Various national and international fabrication codes, standards and specifications are currently being followed to prepare welding procedure specifications (WPS) to qualify the fabrications welding procedures. The procedure qualification record PQR is a document that consists of record of test results on the welded coupon.

Trinity NDT has over two decades of serving the customers through certification of their welders to International standards, codes and specifications. Our team on Welder Qualification tests, Welding Inspection and welding consulting services comprises of Welding experts with decades of welding related experience with leading welding and fabrication companies. Our welding inspectors are certified to American Welding Society AWS-Certified Welding Inspectors, CSWIP 3.1 and other internationally recognized personnel certifications. The panel of experts at Trinity NDT can work together with clients and their counterparts for specific requirements to establish Welder Qualification tests.

Establishing right welding procedure involves:

  • Planning the welding tasks effectively
  • Collecting the data pertaining quality requirements
  • Writing a Welding procedure for use of for trial
  • Making a test weld under the supervision of welding inspector
  • Evaluating the results
  • Approving the procedure for welding
  • Preparing the documentation as per specification or code
After the testing is completed and all the relevant results collated, the results need to be assessed in accordance with the relevant code/standard. The results are then generally recorded
  • PWPS: Preliminary Welding Procedure Specification

Before procedure approval.

    • WPS: Welding Procedure Specification

After procedure approval

    • WPAR (WPQR): Welding Procedure Approval Record

Welding procedure test record

Objective of a welding procedure test

  • To give maximum confidence that the welds mechanical and metallurgical properties meet the requirements of the applicable code/specification.
  • Each welding procedure will show a range to which the procedure is approved (extent of approval)
  • If a customer queries the approval, evidence can be supplied to prove its validity
‘Trinity NDT’ expertise is utilized to perform the following activities related to Welder Qualification tests
 
  1. Preparing Welding Procedure specifications(WPS) as per codes and standards
  2. Witnessing, third party inspection of welder qualifications tests
  3. Preparing WPS, PQR, WPQ
  4. Analysis of Mechanical and metallurgical tests
  5. Carrying out Radiography (X-ray and Gamma ray) Ultrasonic inspection, magnetic particle inspection, liquid penetrant inspection, visual inspection and other NDT inspection tests as the case may be, as per code or standard requirement
  6. Facility for Training welders on various welding processes
