Read production schedules and work orders to determine processing sequences, furnace temperatures, and heat cycle requirements for objects to be heat-treated.

Mount workpieces in fixtures, on arbors, or between centers of machines.

Adjust controls to maintain temperatures and heating times, using thermal instruments and charts, dials and gauges of furnaces, and color of stock in furnaces to make setting determinations.

Position parts in plastic bags, and seal bags with irons.

Examine parts to ensure metal shades and colors conform to specifications, using knowledge of metal heat-treating.

Stamp heat-treatment identification marks on parts, using hammers and punches.

Test parts for hardness, using hardness testing equipment, or by examining and feeling samples.

Clean oxides and scales from parts or fittings, using steam sprays or chemical and water baths.

Repair, replace, and maintain furnace equipment as needed, using hand tools.

Load parts into containers and place containers on conveyors to be inserted into furnaces, or insert parts into furnaces.

Heat billets, bars, plates, rods, and other stock to specified temperatures preparatory to forging, rolling, or processing, using oil, gas, or electrical furnaces.

Record times that parts are removed from furnaces to document that objects have attained specified temperatures for specified times.

Position stock in furnaces, using tongs, chain hoists, or pry bars.

Place completed workpieces on conveyors, using cold rods, tongs, or chain hoists, or signal crane operators to transport them to subsequent stations.

Instruct new workers in machine operation.

Determine flame temperatures, current frequencies, heating cycles, and induction heating coils needed, based on degree of hardness required and properties of stock to be treated.

Mount fixtures and industrial coils on machines, using hand tools.

Determine types and temperatures of baths and quenching media needed to attain specified part hardness, toughness, and ductility, using heat-treating charts and knowledge of methods, equipment, and metals.

Move controls to light gas burners and to adjust gas and water flow and flame temperature.

Start conveyors and open furnace doors to load stock, or signal crane operators to uncover soaking pits and lower ingots into them.

Remove parts from furnaces after specified times, and air dry or cool parts in water, oil brine, or other baths.

Signal forklift operators to deposit or extract containers of parts into and from furnaces and quenching rinse tanks.

Set up and operate or tend machines, such as furnaces, baths, flame-hardening machines, and electronic induction machines, that harden, anneal, and heat-treat metal.

Reduce heat when processing is complete to allow parts to cool in furnaces or machinery.

Set and adjust speeds of reels and conveyors for prescribed time cycles to pass parts through continuous furnaces.
