Instructors

Length: 2 days    CEUs: 1.50    PDHs: 15.00

It is essential to understand how materials respond to the rapid thermal cycle that occurs during most welding operations as well as the resulting properties in the weldments.  These properties are directly related to the material composition and microstructure, the welding process, the weld filler metal, and even the welding techniques used. To be successful, the ferritic (iron-based) materials commonly used in the pressure containing applications of the ASME Codes may require significant differences in the preheating and Post Weld Heat Treatment (PWHT) requirements.

This course provides the information necessary to understand and implement these requirements. It covers the rules for weld preheating, post weld heat treatment, post bending heat treatments (PBHT), and the use of material heat treatments.

The course begins with the basics of welding metallurgy and the reaction to heat treatments. It then provides the background information needed to make decisions concerning the technical needs and the Code requirements for heat treatment. The course also discusses the ASME Code rules addressing preheating, PWHT, and PBHT to highlight the differences between ASME Code requirements and the current efforts to ensure consistency.  The covered Codes include:

ASME Section I, Power Boilers
ASME Section III, Nuclear Power Plant Components
ASME Section VIII, Pressure Vessels
ASME Section IX, Welding, Brazing, and Fusing Qualifications
ASME B31.1, Power Piping
ASME B31.3, Process Piping

The control of the preheating and PWHT is particularly important to the newer materials that are required for high temperature applications. The concerns and the prevention of problems for the control of preheating and of furnace and local PWHT will also be discussed.

In-class exercises and a short workshop will be used to reinforce the heat treatment, preheat and PWHT requirements. 

You Will Learn To
 - Explain the metallurgical effects of heat treatment, including PWHT, PBHT, and materials heat treatments
 - Describe the effects of welding fabrication preheating and PWHT on the properties of the completed product
 - Explain ASME Code requirements for preheating and PWHT
 - Explain the requirements for PBHT in the Codes
 - Describe the controls needed for effective heat treatments

Instructors

Philip D. Flenner, P.E., has spent more than 40 years in welding qualifications, engineering training, power plant maintenance, and performance assessment. He has developed several guidelines on material control, repair methods, and the usage of Codes and Standards for the power industry. Mr. Flenner has also made significant contributions to several codes for piping, welding qualification, and materials over the last 40 years. He was also awarded the ASME Life Fellow during his career. He has taught multiple ASME Training & Development courses, participated in industry research on the effects of PWHT on ASME materials, and been instrumental in sponsoring changes in the Code requirements covering preheating and PWHT.
