Course project, about 12 hours
Loaded infrared survey of a steel rolling mill: MCCs, transformers, busducts and bearings, classified by ΔT
Plan and execute a route survey of a reinforcing-bar mill's electrical and mechanical assets under load. Write the procedure that fixes load conditions, emissivity, reflected temperature, camera settings and arc-flash boundaries. Build the inspection-point register. Check the camera against a reference source. Survey with three-phase comparison and same-machine comparison. Classify every finding by ΔT to the NETA bands, and to any limits in the client's contract. Turn the findings into a repair plan with re-inspection dates. You deliver your own procedure, register, report, calibration record and plan. The sample pack shows what a thermographer hands to the mill's electrical head.

Common questions
Do I need a thermal camera?
No. The course teaches what to point a camera at, in what conditions, and how to judge what comes back. That is the part most camera owners are missing. Every practice task has a version you can do with a notebook and a plant walk. If you do have a camera, or a clip-on thermal module for your phone, use it.
What do I need before starting?
Nothing formal. It is written for electrical and mechanical maintenance staff, substation and MCC technicians, plant reliability engineers and solar site staff. If you can read a single line diagram or identify a bearing housing, you have enough.
Is this the same as a Level 1 thermographer certification?
No, and it must not be described as one. Level 1 thermographer courses are paid and classroom based. They include a practical examination with a camera in your hands. They come from bodies such as the Infrared Training Center, or are built on ISO 18436-7 and ASNT SNT-TC-1A. This course is preparation and background reading for that. EDWartens is not affiliated with any of those bodies and issues no credential on their behalf.
Which standards does it follow?
Most published severity tables online come from American practice such as NFPA and NETA. That includes the delta-T criteria quoted everywhere. The notes say so plainly. They teach the method that transfers: compare like with like under similar load, and record the conditions. Then set your own plant's action thresholds in writing. Do not borrow a table you cannot justify.
How long is the course?
Five content modules and a final. That is about two and a half hours of video lessons, and roughly five hours in total with the practice tasks and practice questions. It is a short foundation course, not a full Level 1 syllabus. It says so rather than padding itself out.
Is the Infrared Thermography Training course really free?
Yes. Every module, practice task and assessment. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.
What certificate does the Infrared Thermography Training course give?
An EDWartens Certificate of Completion, issued when you have finished every module and passed the final at 60 percent, with a verification code anyone can check. It is not a vendor credential and is never described as one.
Who made the video lessons in the Infrared Thermography Training course?
The creators named in the Credits block at the foot of this page, on their own YouTube channels. EDWartens did not make the videos and the creators are not affiliated with EDWartens. What EDWartens wrote is the study plan, the notes, the practice tasks and the assessments.
What topics does the Infrared Thermography Training course cover, module by module?
The Infrared Thermography Training course has 6 modules. It opens with "What a thermal camera actually measures", goes through "Electrical and mechanical inspection", "Building envelope, insulation and moisture", "Solar PV inspection" and "Route surveys, and where infrared stops" and ends with "Final assessment". The full list with minutes is under "What you learn" on this page.
What can I do after the Infrared Thermography Training course?
After the Infrared Thermography Training course: Set emissivity and reflected apparent temperature, and recognise when a shiny surface has made a reading worthless; Plan a loaded electrical survey, record load and ambient with every image, and work safely with an authorised electrician; Classify a hot joint by comparing it with the same connection on the other two phases. These are the practical outcomes the course is written around, and the final assessment of 15 questions checks them.
What software and hardware do I need for the Infrared Thermography Training course, and does it cost anything?
For the Infrared Thermography Training course, software: None required. Camera makers' free report software is discussed in the notes, not needed to finish the course. Hardware: none. A thermal camera, or a clip-on thermal module for a phone, makes every practice task real; each task also has a version you can do with a notebook. The course itself is free.
Is the Infrared Thermography Training course suitable for me, and what level is it?
Infrared Thermography Training is rated beginner. Beginner. No prior thermography experience needed. Any electrical or mechanical maintenance background helps, and a thermal camera makes the practice tasks real but is not required. It is written for maintenance and reliability engineers and technicians, and takes about 4.7 hours at your own pace.
Which jobs use the skills from the Infrared Thermography Training course?
Skills from the Infrared Thermography Training course (for example: set emissivity and reflected apparent temperature, and recognise when a shiny surface has made a reading worthless) are used in roles such as maintenance engineer, reliability engineer, condition monitoring analyst and service technician, and in reliability engineer work. The course gives you practical evidence of the skill; it does not promise a job, and employers decide on experience and interview.
