AIM provides services such as Welding Procedure Specification (WPS), Weld Procedure Development, Welding Procedure Qualification record Witnessing (WPQR), Welder Qualification Witnessing (WQR), WPQR Weld Qualification, Welder (Performance) Qualification, Visual examination, Visual Inspection of welds, Non-destructive examination of welds, all mechanical tests, welding machine calibration such as Current calibration, Voltage calibration and gas flow calibration as required by several standards.
Your Benefits of Our Qualification for Welders
A weld sample is produced prior to commencing the final welding of the product. All welding variables are controlled and recorded when welding the weld sample or coupon. These welded coupons are then tested to ensure that the weld joint will be of acceptable quality. The types of tests involved in weld testing are visual inspection, non-destructive testing such as Radiographic examination (RT), Ultrasonic testing ( UT or UFD), Magnetic Particle test (FMPI or MPI or MT) and Liquid Dye Penetrant Test ( DPI or PT) followed by appropriate mechanical test such as Weld tensile test, transverse test, longitudinal bend test, transverse bend test, impact test, macro examination or macro test, hardness survey or hardness test, weld fracture test, nick break test, fillet break test, corrosion resistance test, metallographic test, microstructure test, ferrite count test, ferrite number test, post weld heat treatment or stress relieving and chemical analysis.
Welding Procedures at a Glance
AIM comprises a team of Metallurgist, Engineers, Welding Engineers and technologist, Welding Supervisors and Inspectors, Scientist, Engineering Technologist and Non-destructive testing Technologist. The combination of these professionals from different speciality ensures that the welding task is completed efficiently and within shortest duration.
The welded sample or coupon is often tested at various stages of fabrication such as for Welding Procedure Qualification Record (WPQR), to qualify Welding Procedure Specification (WPS), to qualify welder as Welder Qualification Record ( WQ or WQR) and to accept the final product in the form of Production Weld test.
Procedure qualification record (PQR)
It is required when it is necessary to demonstrate that your company has the ability to produce welds possessing the correct mechanical and metallurgical properties.
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 inspector
Evaluating the results
Approving the procedure for welding
Preparing the documentation as per specification
