Welding quality plays a critical role in ensuring structural integrity, mechanical reliability, and compliance with engineering requirements across industrial fabrication, construction, and maintenance environments. Effective welding quality assurance depends on established welding procedures, qualified personnel, material compatibility, inspection requirements, and recognized international standards. This training program examines Welder Qualification Testing (WQT) and Welding Procedure Specification (WPS) requirements, including welding processes, essential variables, procedure qualification records, and welder performance qualification criteria. It also explores qualification testing standards, welding inspection requirements, documentation controls, and technical acceptance criteria that support welding compliance, traceability, and quality assurance.
By the end of this program, participants will be able to:
