Your work. Your records.

Heat Treating Workers: Workplace Records

A work order describes the required heat cycle, a removal-time entry documents an event in that cycle, and a hardness test assesses a property of the part tested. If workplace feedback compares these records, connect the part and cycle references first. None of the three should silently substitute for the others.

A record map for your role

What to organize first

  1. Cycle requirement

    Identify the work-order revision and part or batch.

  2. Recorded event

    Separate removal time from shift time and planned duration.

  3. Hardness evidence

    Identify the part or sample represented by the result.

Start with the work you actually do

Set up, operate, or tend heating equipment, such as heat-treating furnaces, flame-hardening machines, induction machines, soaking pits, or vacuum equipment to temper, harden, anneal, or heat treat metal or plastic objects.

O*NET classifies this occupation as Heat Treating Equipment Setters, Operators, and Tenders, Metal and Plastic (51-4191.00). Its description covers a typical occupation, not every workplace or individual job. It does not establish employee status, overtime eligibility or employer misconduct.

  • Read production schedules and work orders to determine processing sequences, furnace temperatures, and heat cycle requirements for objects to be heat-treated.Source task 12087 · updated 07/2016
  • Record times that parts are removed from furnaces to document that objects have attained specified temperatures for specified times.Source task 12088 · updated 07/2016
  • Test parts for hardness, using hardness testing equipment, or by examining and feeling samples.Source task 12102 · updated 07/2016

Identify the required cycle

Record the work-order or schedule revision, part reference and processing sequence supplied for your assignment. Keep a later change to a requirement visibly later in the timeline. Do not derive a temperature or cycle from this guide. If the instruction was incomplete or conflicting, retain the question you raised and the answer you received.

Keep the time entry in context

Identify the removal-time record and the batch or parts to which it refers. Distinguish that event time from the employee shift, planned duration or another clock reading. If a correction was made, retain the explanation and sequence. One timestamp alone does not reconstruct all conditions experienced by the part.

State the scope of the hardness result

Connect a reported hardness result to the part or sample tested and the requirement cited in the feedback. A result on one sample is not a record of every part, and it does not independently reconstruct the earlier cycle. Keep your response to the feedback without changing heat-treatment records or repeating a test to recreate an employment event.

Source context and limits

This guide uses three selected O*NET 31.0 tasks for Heat Treating Equipment Setters, Operators, and Tenders, Metal and Plastic, dated July 2016 (2 core, 1 supplemental). Supplemental tasks describe additional occupational duties, not duties performed in every job. These tasks provide occupational context for organizing an employment record. They are not current operating instructions, inspection standards or a finding about any employer or worker. Follow the authorized procedures at your workplace; the source does not determine whether an employment claim exists.

Choose your next step

Review the workplace retaliation guide, unpaid wages guide, or discrimination guide if those concerns fit your experience. A job title alone does not establish a claim.
