What an NDT Level II technician does day to day

The shape of a typical day

Most days follow the same arc, whatever the method.

1. Read the work. You review the job, the procedure and the acceptance reference that applies, so you know what you are looking for before you touch equipment.
2. Set up and calibrate. You prepare the equipment and check it against reference standards. For UT that means range and sensitivity on a reference block. For MT it means checking the field and the particles. For PT it means checking the materials and process.
3. Examine. You scan, magnetize or process the part to the procedure, in the sequence it requires.
4. Interpret. You look at what you got, sort real indications from false or nonrelevant ones, and size or locate what remains.
5. Evaluate and report. You compare indications to the acceptance criteria and record the result so someone else can follow it.
6. Hand off. Rejects go to the responsible person, and your notes make the decision traceable.

Steps 1, 4 and 5 are the difference between Level II and Level I. They are also where the exam spends its time.

Where the work happens

Level II technicians work in fabrication and machine shops, aerospace and manufacturing facilities, plants and refineries, pipelines and field sites. Shop work means steady conditions and repeatable setups, while field work means weather, access, travel and shifts that change with a project. Our jobs and career path article goes through the settings and what postings ask for.

Your method shapes the day. A UT technician might measure wall thickness on a vessel in the morning and scan a weld in the afternoon. An MT or PT technician might process a tray of parts in a shop all day. Each has its own rhythm, and which method to certify in first compares them.

Skills that make the difference

• Reading procedures. The procedure sets the conditions, and your job is to follow them and spot where a job does not fit.
• Basic math. UT in particular uses algebra and trigonometry: skip distance, beam angle and decibels. The math refresher shows the level required.
• Judgment about indications. Telling a real flaw from geometry or a process artifact is the core skill.
• Clear records. A result no one can reproduce or audit is of little use, so you write down the part, area, method, settings, observation and evaluation basis.
• Calm under repetition. The hundredth part gets the same care as the first, and that consistency is what employers prize.

A closer look at one job: a weld scan

Picture a UT technician scanning a butt weld. They confirm the procedure and the acceptance reference, calibrate range and sensitivity on a reference block, mark scan areas on the plate and apply couplant. The probe moves back and forth beside the weld, and the technician watches the screen for signals that stand out from the usual geometry echoes.

When a signal appears, the work slows down. They record its position along the weld, its depth, its height against the reference level and its length, and they check it from another angle to see whether it behaves like a flaw or like geometry. The report then states what was found and which criteria it was judged against. None of this is guesswork, and all of it is the kind of reasoning the exam tests, which is why geometry and calibration questions carry so much weight.

What the credential shows

Employers hire Level II because it shows you can be left to run an examination. Under ASNT's program that means meeting training and experience requirements for your method and passing the General and Specific written exams, with the employer handling practical and job-specific checks. The requirements guide lists the numbers per method, and the route comparison explains how employer certification differs. Once you hold a credential, others can check it, as the verification guide shows.

Pay depends on method, shift, location and overtime, and the pay guide gives the BLS benchmark and posted ranges, with sources.

The parts people do not expect

Expect more writing than you think, and more waiting. Access can take longer than the test, equipment needs checking before every shift, and a rejected part usually means a conversation with the person who owns the repair. Technicians who communicate findings plainly, with the facts and the reference they relied on, become the ones supervisors trust with harder jobs.

Getting from here to there

If the day above sounds like work you would like to do, the next step is practical: pick a method, log your experience and start with the General exam topics. The UT General guide lists the six UT topics, and the 30, 60 and 90 day plan turns them into a schedule.

FAQ

What does an NDT Level II technician do?

A Level II sets up and calibrates equipment, performs examinations to a procedure, interprets results, evaluates them against acceptance criteria and reports. In many shops they also guide Level I technicians on the job.

Is it a desk job or a field job?

Neither alone. The hands-on work is in a shop or on site, and the reporting is done at a desk or on a tablet. Which one dominates depends on your employer and method.

Do I need a degree?

ASNT's Level II requirements are stated as training days, experience days and exams, and they do not list a degree. Employers set their own hiring criteria, so read postings for the roles you want.

Which skills should I build first?

Start with reading a procedure carefully, basic algebra and trigonometry for UT, and clean record keeping. The General exam topics for your method cover the rest.
