Abstract:

This manuscript suggests a methodology to recognize the most vulnerable welding procedure specifications (WPSs) that contribute to the majority of defective welds annually. Based on the identified WPSs, it also suggests a methodology to recognize the most critical imperfection groups and the related imperfection sub-groups as specified in NS-EN ISO 6520-1.
