A Welding Procedure Specification (WPS) is a guiding document in any welding quality management program. This workshop will explore that role and guide the participants through the process of writing and qualifying a WPS that is ASME Section IX compliant, metallurgically sound, and meaningful to the welder.

This includes live demonstrations on the welding of the coupon; test specimen location and preparation; tension, bend, and charpy testing; evaluation of the test results; and generation of the procedure qualification record(s) (PQRs) and WPS.

Topics include:

• What is a WPS?
• Why are WPSs necessary and who cares about them?
• How various industries and codes address welding procedure qualification
• Understanding qualification “variables”
• What comes first? The WPS or the PQR?
• What questions does one need to ask to develop a WPS?
• How to qualify multiple welding processes and/or filler metal classifications using a single test coupon
• When and how to amend an existing WPS to extend the qualification range(s)
• Addressing heat-input control for WPSs qualified with toughness
• Sources for reasonable and meaningful ranges for variables on the WPS
• Avoiding the common mistakes in WPS qualification

* Registration is limited to 20 students
