Welding WPQR

Welding Procedure Qualification Record

The main objective of WPQR is to test welded products by various methods in order to assure the required quality of weld joints and to significantly reduce the risk of possible defects and accidents.

Welding Procedure Qualification Record (WPQR) is issued by the Czech Welding Institute. These exams are recognized by international organizations and producers.

The certification for welding WPQR is recommended to all companies that seek to assure consistent quality of weld products and to improve their competitiveness.

Procedure to Obtain the Certification for WPQR

•Non-destructive testing
Visual method
Capillary method
Method of whirling flows
Ultrasound method
•Destructive testing
Tensile test of a weld joint
Tensile test in the transverse direction
Bend test parallel to the welding direction
Bend test transverse to the welding direction
Crash test.
•Macroscopic, microscopic test and other valuations
Macroscopic test
Hardness testing
Testing the fracture toughness of a weld joint
Weld-notch toughness testing
Corrosion resistance testing
Metallographic test
Test of microstructure
Ferrite number testing.

Benefits of the Certification

•Ensuring the appropriate quality of weld joints
•Minimizing the risk of defects and accidents
•Trust of suppliers and clients
•Compliance with legal and regulatory requirements

To perform tests of different type, we cooperate with laboratories across the world in which we send samples for testing if necessary.
