Materials Testing, Materials Engineering and Welding Technology

Modern materials and their constant further development constitute the basis of competitive industrial production. The market constantly demands new products for new applications. Even with the most modern and best production facilities, no satisfactory result can be achieved if the materials used do not meet requirements. This makes findings in materials testing particularly important.

    The Right Steps

    Quality right from the outset
    Quality cannot be “tested into existence”. This means that quality-determining features must be taken into account right from the planning stage. A number of factors are important, such as: legal and/or normative requirements, calculation, design and the choice of materials. Joining techniques and test methods used for quality assurance must also be taken into account. TÜV AUSTRIA’s Materials Engineering and Welding Technology Division is your partner for economical and competent handling of such tasks.

    TÜV AUSTRIA offers a comprehensive and diverse range of services for this purpose.

    • Adaptation of test methods according to your requirements
    • Assistance with planning and design
    • Consulting on selecting and approving test methods
    • Welding consulting

    Learning from Damage & Avoiding Mistakes

    Component failure is one of the most dreaded risk factors in production and business operations. Injuries and damage cannot always be avoided, even when using the latest planning and production methods.

    TÜV AUSTRIA’s Competence Center for Plant Diagnostics and Damage Analysis helps to analyze injuries and damage that have occurred and to develop strategies to prevent any further damage.

    In combination with modern testing methods, our experts’ knowledge guarantees that problems can be identified and reliably solved.

    Our range of services for injury and damage investigations includes:

    • Consulting and conceptual planning for injury and damage analysis
    • Documentation of the extent of injury/damage
    • Expert sampling on site
    • Physical-chemical and mechanical investigations on site and in the laboratory
    • Ambulant metallographic investigations
    • Supportive interior inspection by video endoscopy
    • Expert evaluation of investigation results by specialists

    We solve testing and inspection problems

    New demands are constantly being placed on non-destructive testing techniques by new materials and rapid technological development. In cooperation with industry and trade as well as international partners, TÜV AUSTRIA’s Materials Engineering and Welding Technology Division develops tailor-made solutions for our customers’ testing and inspection problems.

    Our staff are trained in all currently used testing techniques and certified according to EN 473.

    We come to the customer. We currently have 17 mobile testing laboratories ready for Austria-wide and international testing deployment.

    The following test methods are currently used as standard by TÜV AUSTRIA:

    • Radiographic testing
    • Ultrasonic testing
    • Acoustic emission testing
    • Stress and strain measurements
    • Pressure and leakage testing
    • Pulsation and load-change tests
    • Development of test methods according to customer requirements
    • Development and use of “smart pigs” for pipeline inspections

    Competence Center for Plant Diagnostics and Damage Analysis

    TÜV AUSTRIA uses analytical procedures, modern testing methods and extensive experience to prevent injury and damage that can result in unplanned outages with expensive repairs and possible consequential costs. Systematic risk analyses and methodical procedures are used to identify risk potential and develop action plans.

    TÜV AUSTRIA saves time, nerves and money:
    As an old saying goes: “Getting hurt makes you smart.” Unexpected damage may make you smarter, but certainly also poorer. The aim of TÜV AUSTRIA’s work is to prevent injury and damage and thus costs by means of preventive measures.

    With on-stream measuring methods and state-of-the-art analysis procedures, diagnosis is carried out of incipient damage caused by continuous stress. This allows conclusions to be drawn about the time span for safe continued operation of a plant or the need to undertake a replacement investment in good time. If, on the other hand, damage has occurred, it will be analyzed with great care so that the necessary action can be taken quickly to prevent any repetition.

    A special service for the insurance industry is assessment of a company’s risk potential. TÜV AUSTRIA’s experts get to the bottom of causes in cases of damage or impending damage. Together with the customer, they develop strategies and solutions for avoiding problems in the future.

    What does TÜV AUSTRIA provide?
    Hazard and risk analyses of technical plants and processes:

    The aim of a risk analysis is to obtain a general overview of existing risks and, if necessary, to identify any need for action. Consideration is given to effects on people, the environment and property which may be caused by divergences from normal operation.

    Risk management:

    Systematic evaluation of the following key factors influencing safety, security and availability, doing so as a basis for identifying and reducing risks: equipment integrity, technical risk analysis, procedures and workflows, training and education, legislative compliance, management of opportunity, maintenance, contingency planning, learning from incidents of injury and damage.
    Risk based Inspection (RBI) of pressurized components:
    Specific definition of required inspections and tests of pressurized components as a function of the harmful mechanisms at work and the consequences of a failure.

    Identification of local inadmissible heating:

    This is done using, for example, thermographic methods for electrical controls, bearings and other rotating parts so as to prevent possible damage to the plant.

    Failure analysis of components and materials using materials science investigations such as metallographic investigations based on properly taken samples:

    Conventional metallography and scanning electron microscopic examinations (SEM, EDX analyses) are used, including micro- and low-load hardness tests as well as metal analysis (optical emission spectrometry), microscopic and macroscopic examinations of fracture surfaces. Investigations into corrosion damage.

    Component metallography, i.e., microstructural investigations of components themselves without taking samples using replica technology, underpinned by accompanied by mobile hardness testing, mobile metal analysis and wall thickness measurements done by ultrasound.

    Computational verification of components in accordance with relevant regulations and the latest state of knowledge:

    TÜV AUSTRIA’s experts have a large number of state-of-the-art computer programs at their disposal running on powerful computers. Mechanical and thermal loads can be traced and evaluated using complex simulation programs.

    Risk analyses for the insurance industry:

    Analyses of damaging events in the area of machinery breakdowns and in electrical installations are not only important for reasons pertaining to insurance contract law, but they also serve to prevent damage. Preventive risk analyses for harm prevention are equally important.
    ... all the way to risk analysis of large-scale plants, such as determining explosion risks at oil refineries, the Competence Center for Plant Diagnostics and Damage Analysis covers the entire spectrum of preventive and subsequent damage analysis.
