Job profiles

Heat treatment operator

  • Hours

    40 per week

  • Starting salary

    £15,000 + per year



The work

Heat treatment operators oversee the machines and equipment that apply treatments to metals and metal components. They clean, harden, temper (strengthen) and anneal (soften) metal and make it ready for use in components used in the construction of a range of products. These include cars, aircraft, trains, oil rigs and specialised items for the armed forces. Some are small components such as tools and cutting equipment, gear wheels and bearings.

As a heat treatment operator, you would work with a variety of metals, including iron and steel. Your typical duties would include:

  • loading untreated products into a furnace or tank
  • setting the temperature controls for a particular treatment
  • monitoring the process, adjusting times and temperatures in line with instructions
  • removing products from the furnace and air drying, or cooling them in water, oil or chemical baths (known as quenching)
  • cleaning oxides and scale from parts or fittings using steam sprays or by washing them in chemical cleaning solutions
  • testing samples for hardness and other properties to make sure they meet the manufacturer's specifications
  • recording test results on a computer system.

You would use a range of equipment such as gas and vacuum furnaces, salt baths, chemical solutions and welding torches to harden (anneal) metals and metal alloys. You would do some of these jobs using automated equipment and you may also be responsible for programming instructions into the machines.


Hours

You would normally work 40 hours a week, often on a shift rota which may include evenings and weekends.

Most of your work would take place in factories and workshops, where conditions can get hot, dirty and noisy. The job also requires lots of standing and lifting. You would need to wear protective clothing for most tasks.


Income

Starting salaries can be between £15,000 and £18,500 a year. Once trained, operators may earn up to £28,000 a year. Experienced operators can earn up to £40,000.

Figures are intended as a guideline only.


Entry requirements

You do not usually need qualifications to work as a heat treatment operator. However, some employers may ask for GCSEs or equivalent qualifications in subjects like maths, English, technology or engineering. You may have an advantage when looking for work if you have previous engineering experience.

You may be able to get into this career through an Apprenticeship scheme. The range of Apprenticeships available in your area will depend on the local jobs market and the types of skills employers need from their workers. To find out more about Apprenticeships, visit the Apprenticeships website.

To get on to an Apprenticeship, you are likely to need GCSEs (grades A-E) in subjects such as English, maths, science and technology, or equivalent qualifications.

You could also take college courses which would teach you some of the skills needed. Relevant courses include:

  • BTEC Certificate/Diploma in Manufacturing Engineering (options in metallurgy)
  • City & Guilds Certificate in Engineering
  • EAL Certificate in Engineering.

For more details about engineering careers, qualifications and training placements, contact SEMTA.

Also see the Tomorrow's Engineers website for more general information about engineering as a career.


Training and development

Once you are working, your employer will normally train you on the job. Safe working practices are important, so your training will include basic first aid procedures and how to deal with emergencies.

You could also work towards NVQ qualifications, such as:

  • Performing Manufacturing Operations levels 1and 2
  • Performing Engineering Operations levels 1 and 2.

The Wolfson Heat Treatment Centre (WHTC) in Birmingham also offers training in understanding heat treatments. To find out more, see the WHTC website.

Industry summary

The metals industry is part of the engineering manufacturing, science and mathematics sector, represented by Semta Sector Skills Council. This sector also includes the following industries: automotive manufacture; electronics and electrical equipment manufacture; mechanical equipment manufacture; transport equipment manufacture, including marine and aerospace; and science. Across the sector as a whole, the workforce comprises approximately 2 million people, working across around 75,000 companies. UK engineering and science turnover is over £250 billion. British engineering exports amount to 37% of total UK exports of goods and services. The UK is Europe’s top location for investment in pharmaceutical and biotechnology research and development.

The UK metals industry comprises:

  • Manufacture of basic metals – companies that are involved in the smelting and refining of ferrous (e.g. iron and steel) and non‐ferrous metals (e.g. copper, silver, aluminium) as well as those that produce bars, rods, tubes and carry out casting of metals.
  • Manufacture of fabricated metal products – companies that manufacture structural metal products (such as tanks, reservoirs, prefabricated metal buildings, steam generators), treating and coating of metal, manufacture of cutlery, tools and general hardware and other fabricated metal products (such as metal packaging, screws, washers and other metal fasteners). This has the largest number of employees of all of the metals sub‐industries.
  • Wholesale metals and scrap – companies involved in the wholesale of metals and metal ores and wholesale of waste and scrap. Energy savings can be made from the recycling of metals, especially aluminium, rather than extraction from ores. There is much interest in how to make‐up components with a view to disassembly and recycling at the end of a products lifecycle.

Research developments in the molecular structure of the materials and manufacturing processes have led to their extended use in modern buildings, vehicles, engines and turbines that as well as having applications in the aircraft industry, help to harness the energy of wind and waves.

Key facts:

  • There are an estimated 412,600 people employed in the metals industry, across 33,240 workplaces in Great Britain.
  • The greatest concentrations of employment in the metals industry are in the West Midlands, Yorkshire and the Humber and the North West.
  • 90% of the metals workforce is full‐time.
