Course Outline

Covers heat treatment requirements for the fabrication of pressure vessels, steam generators and process equipment. The following fabrication codes are dealt with in this course: ASME VIII, BS2633, EN13445, EN13480 and AWS D1.1.

Basic metallurgy; heat treatment definitions; welding processes; welding effects on materials – why is heat treatment necessary?; heat treatment cycles, heating and cooling rates, soaking  temperatures, soaking times; code and material specification requirements for welding; pre-heat, post-weld heat treatment, normalising, annealing, hydrogen removal; methods of heat  treatment; equipment.

Determining pre- and post-weld heat treatment requirements to codes and standards; determining heating and insulation band widths; determining heating configurations on nozzles; setting up equipment for weld heat treatments – thermocouples, heaters, insulation; operating heat treatment equipment.
