Vacancies for the position of Flaw Defect Technician in the all-Russian vacancy database

A flaw detector is a specialist who is engaged in identifying defects, mechanical damage and defects in production. For example, a flaw detection engineer at a carriage depot checks the wheelsets of a railway train for cracks and damage during operation.

To work, people in this profession need special measuring instruments. Flaw detectors working on railway tracks detect defects using flaw detection carts or wagons.

The profession of a flaw detector is the most important and responsible in metallurgical production. Products produced at the plant are necessarily carefully checked by specialists for hidden defects, which cannot be noticed without the presence of ultrasonic equipment.

What a flaw detector should know

A flaw detector engineer is a rather complex and responsible job. He is responsible for the quality of products produced at the plant, for the life and safety of passengers when working in the railway transportation industry. It is not surprising that employers have a number of requirements for applicants for this position. The flaw detector must know the following:

• regulations relating to occupational safety and methodological acts of the state measurement system;
• types of possible defects, design features of the test object, potential danger during measurements;
• methods and technical documentation for non-destructive testing;
• rules for selecting and checking the quality of materials;
• types of defects, their classification, signs by which a defective part is identified.

Responsibilities of a flaw detector

Many people ask the following question: “Who is this flaw detector? What does he do?” A flaw detection engineer has a number of job responsibilities in the workplace, which are listed below:

• carrying out work related to non-destructive testing and diagnostics of tested products;
• planning the work and carrying out quality control during its implementation;
• checking the quality of measurements taken by subordinates;
• drawing up a report on the quality of the test sample;
• ensuring the safety and operability of measuring equipment;
• monitoring of simple and complex parts in their configuration on stationary and mobile devices (flaw detectors);
• eddy current testing of cylindrical parts;
• adjustment, if necessary, of ultrasonic and electromagnetic type;
• preparation of magnetic suspensions;
• checking parts for the presence of delaminations, recording the boundaries of delamination if detected using a special device;
• keeping records of work performed.

Education

The position of flaw detection engineer is in high demand in our country. There is no shortage of qualified specialists in this field on the labor market. According to data received from the Russian Ministry of Labor, in January 2016, the vacancy of a flaw detector (non-destructive testing specialist) was included in the list of the most in-demand professions.

Training to become a flaw detector consists of acquiring knowledge regarding the principle of operation of a flaw detector, its main purpose, and the functions of controlling the device. Students will also take courses on the topic “Basic concepts of electrical engineering.”

After successful completion of training, the flaw detector operator receives the following professional skills:

1. Checking the quality of welding using magnetic equipment.
2. Fixation of permeability in austenitic steels depending on the amount of ferrite.
3. Diagnostics and identification of surface defects, calculation of their coordinates and area.
4. Diagnostics of the equipment used, namely flaw detectors, depth gauges and converters.
5. Quality control of welds and rolled low-alloy carbon steel using an ultrasonic device.

Career Opportunities

Flaw detector equipment

Many people are interested in the question: “Who is this flaw detectorist? What functions does it perform? To answer this question, a flaw detector is needed.

The word “flaw detector” came to us from the ancient Greek and Latin languages, and literally translated means “I observe a defect.” This device is designed to detect defects in products made from various materials. In this case, the non-destructive testing method is used. These defects include:

1. Heterogeneous structure of the part.
2. Violation of continuity.
3. Deviation from specified dimensions.
4. Change in chemical composition.
5. Corrosion damage.

Where are flaw detectors used?

To answer the question: “Who is this flaw detector?” - you should know where the device is used to detect defects. Flaw detectors are necessary for vehicle inspection, for production control at machine-building plants, in the chemical industry, construction, energy, in scientific laboratories and in many other industries.

Equipment for detecting defects is used to control the quality of parts, workpieces, welded, adhesive and soldered joints. Some instruments are capable of inspecting products that move at high speed, such as during pipe rolling. Also, some flaw detectors are capable of operating while moving at high speed, for example, wagons or carts equipped with the necessary equipment. Metallurgical plants often use flaw detectors that can inspect parts heated to high temperatures.

History of the creation of the flaw detector

To understand who flaw detectors are and what they do, it is worth knowing a few historical facts about the history of the creation of flaw detectors. The Curie brothers first noticed the reversible effect of piezoelectric pulses in 1880. This discovery made it possible to use quartz to convert electrical vibrations into sound vibrations.

The first flaw detector was created thanks to D. Lachinov at the end of 1880. Its main purpose is to detect a break in the electrical circuit.

But more modern flaw detectors, operating using echo-pulse signals, were assembled in 1943 by two companies almost simultaneously: the American Sperry Products and the English Kelvin and Hughes.
