용접 (WPQR)
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.
