ASME Section IX – Welding Qualifications

This course provides a practical understanding of ASME Section IX requirements for welding and welder qualifications. It explains the principles and requirements used to qualify welding procedures and welding personnel. Participants will learn about Welding Procedure Specifications (WPS), Procedure Qualification Records (PQR), and Welder Performance Qualifications (WPQ). The course covers essential variables, supplementary essential variables, and non-essential variables used in welding qualification. It explains the selection of materials, welding processes, joint designs, filler metals, preheat, interpass temperature, and post-weld heat treatment requirements. Participants will understand the qualification ranges and limitations applicable to different welding procedures. The course also covers mechanical testing requirements, including tension, bend, and other applicable tests. It introduces the interpretation and preparation of WPS, PQR, and welder qualification documents. Practical examples are used to explain how ASME Section IX requirements are applied in fabrication and inspection activities. The course supports effective welding quality control, documentation, and compliance with applicable ASME requirements.
