Theory:
- 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.
Practical:
- 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
