Heat treating often is called Post Weld Heat Treatment (PWHT) or Stress Relieving. It involves heating work pieces (for example, pipes or vessels) to high temperatures in a controlled manner and maintaining those temperatures for a prescribed time, then cooling work pieces at prescribed rates to achieve the required properties. Field heat treatment technicians use a variety of heat treatment methods (for example, electrical resistance heating, combustion fuel firing or electrical induction heating). They also may do other heat-related work such as:

  • Hydrogen bake outs
  • Pre-heating
  • Refractory curing
  • Heat alignments
  • Lower temperature line heating

In general, field heat treatment technicians:

  • Analyze job requirements, including technical documents for heat treatment applications
  • Load, assemble, disassemble and maintain heat treating equipment
  • Use capacitor discharge units to fasten, secure or weld thermocouples to work pieces
  • Install and remove thermal heating pads, electrical resistance heaters, induction coils and insulation
  • Distribute and connect secondary power cables to heating elements and thermocouples
  • Control and monitor measurement equipment, instruments, digital process controllers and computer operated systems
  • Operate portable and mobile control systems, including generators
  • Identify, analyze and interpret codes and quality control programs for heat treatment applications
  • Troubleshoot heat treatment equipment and installations
  • Interpret isometric, schematics, blue prints and other drawings relating to piping systems, vessels, and applicable work pieces
Working Conditions
Updated Mar 31, 2020
  • Strength Required Lift over 20 kg

Field heat treatment services are typically provided on a contract basis to clients engaged in the construction, maintenance or operation of facilities that have welded structures, piping or vessels (for example, refineries, power plants, fabrication facilities, pipelines, mining and steam assisted gravity drainage operations).

Field heat treatment services are provided throughout the year, often in outdoor environments and sometimes in adverse weather conditions. The work environment may include any combination of high noise areas, working at heights, confined spaces and congested work sites. Field heat treatment technicians can find themselves in remote locations or shop environments.

Hours of work vary from long term scheduled shifts to short notice "call out" projects. Overtime often is required to meet production and start-up deadlines. Depending on the contractor’s workload, extensive travel and extended stays away from home may be required.

Safety precautions are required to reduce the risk of injury. Most work sites and contractors require pre-employment, periodic and/or random drug and alcohol screening.

Heat treatment equipment can be large and bulky. Technicians occasionally must lift items that weight up to 25 kilograms.

Traits & Skills
Updated Mar 31, 2020

Field heat treatment technicians need:

  • A safety-conscious attitude
  • Strength and stamina
  • Oral and written communication skills to keep records and explain procedures
  • The ability to work at heights
  • The ability to work alone or with others

They should enjoy working at a variety of work sites and in varied conditions.

Educational Requirements
Updated Mar 31, 2020
  • Minimum Education Designated Occupation

Employers generally prefer to hire applicants who have a high school diploma with a strong background in science, the ability to do trade math, good English verbal and written communication skills, and the ability to read technical documents written at a Grade 12 or higher reading level. Field heat treatment technicians need to be well-versed with the technology used in the industry (digital control, measuring instruments, software), and to understand the principles of metallurgy, electricity, combustion and heat transfer.

A trade or technology certificate in one of the welding, machining, pipe or metalworking trades is an asset but not required. Employers may provide the safety training required for working on industrial sites, working at heights and working with hazardous materials (for example, Industrial First Aid, H2S, Confined Space, CSTS, WHIMIS, Working at Heights, Fall Protection).

Field heat treatment technician is a designated trade in Alberta. Certification is available from Alberta Apprenticeship and Industry Training but is not required to work in Alberta.

Applicants  must have at least 48 months of training and 7,200 hours of work experience. Formal classroom training is available through the Quality Control Council of Canada.

Applicants who have related training or work experience may be eligible for admission, credit, or certification. Credits may reduce the hours required.

Employment & Advancement
Updated Mar 31, 2020

Field heat treatment technicians work for companies that specialize in providing contract heat treating services. This work is highly specialized and international so there are relatively few people employed in this occupation compared to the number of people employed in associated trades and occupations.

Most heat treating work in Alberta is on high pressure welded piping systems and vessels used for refining, chemical processing or power generation. Well trained, certified field heat treatment technicians are in high demand.

Field heat treatment technicians are part of the larger 2011 National Occupational Classification 2212: Geological and mineral technologists and technicians. In Alberta, 82% of people employed in this classification work in the following industries:

The employment outlook [pdf] in this occupation is influenced by a wide variety of factors including:

  • Trends and events affecting overall employment, especially in the industries listed above
  • Location in Alberta
  • Employment turnover (when people leave existing positions)
  • Occupational growth (when new positions are created)
  • Size of the occupation

In Alberta, the 2212: Geological and mineral technologists and technicians occupational group is expected to have an above-average annual growth of 2.1% from 2019 to 2023. In addition to job openings created by employment turnover, 39 new positions are forecasted to be created within this occupational group each year.

NOC groups often include several related occupations. Although there is labour market data for the larger NOC group, this occupation makes up only a part of that group. It means data for this occupation may be different than the data shown. For example, only some of the new positions to be created will be for this occupation. It also applies to other data for the NOC group such as number of people employed.
