Preheat Postheat Interpass Temp. PMI Plasma Cutting PWHT

This comprehensive course is designed to give you in-depth knowledge of vital concepts like Preheat, Postheat, Interpass Temperature, PMI (Positive Material Identification), Plasma Cutting, and PWHT (Post Weld Heat Treatment), which are crucial for professionals working in welding, fabrication, QA/QC, and inspection roles in the oil & gas and manufacturing industries.

In today's competitive job market, understanding these thermal and quality control processes is essential for ensuring weld integrity, safety, and code compliance. This course explains not only the theoretical concepts but also provides practical insights with visuals and examples.

You'll begin by understanding the need and process of preheating and post-heating, followed by a deep dive into PWHT procedures, including temperature control, heating rates, holding times, and real-time inspection requirements.

The course also covers PMI methods used to verify base material and weld chemistry using handheld devices like XRF/Optical emission analyzers. Plasma cutting process fundamentals, including gas selection, cutting speed, and edge quality, are also discussed.

Special attention is given to critical standards and real-life applications, including hardness testing, stainless steel pickling/passivation, purging methods, and pipe schedule understanding.

Visual case studies, diagrammatic explanations, and test preparations make this course ideal for aspiring and experienced engineers, welders, and inspectors.

Whether you are preparing for a field job in a refinery, offshore project, or fabrication yard, this course will enhance your technical skills and help you stand out in QA/QC and welding roles.
