To introduce the various welding and cutting processes, this course gives an understanding of AWS filler metals specifications, types of welding flaws, related ASME Section V requirements for NDE, and the QA systems necessary for welder performance qualification as described in the Alberta Welding Examiner Syllabus for Papers #1 and #3. This course is also an excellent learning experience for people seeking a general knowledge in welding and related NDE.
WHO SHOULD ATTEND
Inspectors, welders, welding supervisors, quality control personnel, technologists, and engineers involved with welding for new fabrication, repairs, maintenance, and inspection for pressure vessel or piping. This course is also designed to assist Alberta Welding Examiner Paper #1 and Paper #3. However, being an exam candidate is not required. This course is also recommended for general knowledge.
