Welding procedure qualification and welder examination

Welding procedure qualification record (WPQR)
The test process and result evaluation were carried out to verify the correctness of the proposed welding process. The purpose of welding procedure evaluation: 1. evaluate whether the welding unit is capable of welding the welding joints meeting the requirements of relevant industry standards and technical specifications; 2. verify that the welding procedure specification (WPS or pWPS) prepared by the welding unit is correct. 3. provide reliable technical basis for the development of formal welding process instruction or welding process card.
Training for designers and welding personnel: 1. train designers and welding personnel to better understand ISO, ASME, AWS and other welding standards; 2. review and modify welding process specification on the basis of real working conditions; 3. train welding personnel to carry out welding work with correct procedures and techniques; 4. to advise welding personnel to avoid welding failure and certification failure.
Certification of welding process and welding personnel: 1. test the raw materials of the product according to relevant technical standards or technical documents; 2. witness welding process and test in laboratory to meet the standards; 3. provide qualification certificate based on test results; 4. verify the qualification of welding personnel and the performance of products based on the standards.
Brief introduction to international welder certificate
Welder is a tailor in various metal material manufacturing and industry. His welding skills not only determine the quality of products, but also directly related to the personal safety of product users. The EU believes that only qualified welders can ensure the degree and quality of welding work.
The function of international welder certificate
1. master the welding operation skills applied in different industries, improve the quality of welding seam and welding efficiency.
2. master solid welding theory to guide and solve welding defects, and become a technical talent in welding field.
3. develop occupational safety habits and fire awareness, so that students can avoid or minimize accidents in actual production.
