Brief Introduction of the Department

Research& Development department has been established in 2016. Main goal of the department is to deliver comprehensive technology solutions and helps the ATG company to be a global technology leader in Non-Destructive Testing (NDT). Currently, the department activities are focused on fully autonomous NDT systems in accordance with Industry 4.0 principles, that are usually implemented to highly customized NDT devices, equipment and systems. Main focus of the company as well as the department is in magnetic particle testing (MT), ultrasonic testing (UT), visual testing (VT), penetrant testing (PT), eddy-current testing (ET) and radiography testing (RT) methods of NDT. These methods are various physics principles used to detect structural defects in industrial products (e.g.: airplanes, pressure vessels, cars …) that may endanger their safe operation, potentially causing financial losses or even losses on lives. Any of the above mentioned methods requires further development and integration of software, electronics, control systems, vision systems, manipulators, robotic systems, water managements, special components, self-diagnostics and calibrations systems etc. The R&D staff is specialized on various areas like programming of the desktop applications, control of PLC and the robotic systems, designing of the optical and vision systems, etc. All projects may be categorized as a highly applied research and development, having tangible outputs in real-life applications on the equipment for ATG´s customers from aerospace, railway, automotive, oil & gas and other industries.

Internship Job Description

The job is focused on experimental activities, measurement, programming and optimization works related to development of unique magnetic particle testing (MT) testing devices (equipment), which uses magnetic field and special liquids bearing ferromagnetic particles to visualize invisible defects on the surface of tested products and components. Such MT device has several critical components, where the most important are based on

the system of magnetization (saturation of the ferromagnetic product by sufficiently strong magnetic field which (with using of special liquids) enables detection of invisible defects as cracks of the surface)
the electromagnetic field measurement devices (material structure testing applications)
the optical devices / vision systems (for autonomous surface defect monitoring)
the bin picking systems (loading products subject to the tests into the testing device from a box with randomly oriented products)
the software for evaluating defects according to requirements

These components may be grouped in two main areas – electromagnetic applications tasks and vision applications tasks. Electromagnetic tasks include measurement of electromagnetic field and/or measurement of residual magnetism and/or eddy current material checking. Vision tasks include bin picking experiments and/or etalon verification and/or optimization of optical diagnostics functions and/or defect evaluation programming e.g. measurement of defects length, orientation, quantity, arrangement. Based on the interest and background of the intern one, or both directions maybe subject to the internship.

Internship Job Description

Generally, the job is focused on experimental activity, measurement, optimizations and partially programming works related to ultrasonic testing (UT). Ultrasonic testing NDT method uses propagation of sound on high frequency (usually >500kHz) and a set of their emitters and receivers and special liquid medium (couplant) to detect and characterize subsurface structural defects on metallic and/or composite products. Research and development activities are focused of automated ultrasonic immersion systems for testing of shaped composite structures for aerospace industry. The device consists of robotic system, special water circuit system, ultrasonic system with appropriate designed probe head, data acquisition synchronized system and control and data acquisition (DAQ) software. The development can be divided into the three main topics:

measurements (checking) of composite and/or metal structures by conventional and phased array ultrasonic systems
optimization of water circuit system and water jet
programming new software functions

Measurements (checking) of the composite and metal structures include checking of the material by several ultrasonic techniques, collection of set area scans, their comparison and evaluation. Optimization of the water circuit system and the water jet include testing of different water circuit configuration; design, simulation and experimental verification of water jet for laminar flow. Programming new software functions in National Instruments LabView development environment include the statistical function, the image processing functions, the result measurement features, etc. Based on the interest and background of the intern one, or more directions maybe subject to the internship.
