Mechanical engineering

Goods in the most diverse sizes and types are fabricated in mechanical engineering. It encompasses products such as planned microsubmarines for cleaning blood vessels via household appliances, engines and turbines right up to gigantic tunnel drilling machines and brown coal excavators. Important scientific subdisciplines of mechanical engineering are, amongst others, materials engineering, thermodynamics, technical mechanics, fabrication technology, flow mechanics, drive technology and design theory.

In Germany, mechanical engineering is one of the leading branches of industry. In this country, a turnover of approx. € 130 billion per year, including approx. 60 % in exports, is earned with approx. 900,000 employees.

The material utilised most frequently in mechanical engineering is steel, in addition to other metals such as aluminium and plastics. In mechanical engineering (in contrast, for example, with structural steel engineering), steel is frequently treated during utilisation and processing in order to achieve certain targeted material properties. Quenching and tempering, surface hardening, nitriding or flame and plasma spraying in order, for example, to obtain highly wear-resistant surfaces may be cited as examples here. Furthermore, components made of materials with different properties are frequently joined in mechanical engineering in order to take account of various loads. Valves in automobile construction are frequently friction-welded from two parts. In this respect, the shaft must be particularly wear-resistant and the plate both wear-resistant and high-temperature-resistant.

In contrast with a large number of other sectors, far more welding processes than the classical processes such as manual electric arc, MIG/MAG, TIG and submerged arc welding are utilised in the field of joining technology in mechanical engineering. A large number of resistance, induction and laser processes are utilised in particular. These processes are often optimised and automated for the fabrication of a product line. Because black-and-white joints are also frequently required, there is a demand for qualified welding specialists during fabrication.

GSI supports mechanical engineering for all terms of reference relating to fabrication technology and for the qualification of the employees. This begins with the training of welding engineers and technologists and their regular further education. We qualify welders in mechanical engineering for the tasks in question.

We provide you with competent advice with regard to all joining technology questions. At our research facilities, mechanical engineering finds the right cooperation partners for process optimisation from technical and economic viewpoints in order to implement solutions with a reliable future in a target-oriented way. We have specialised in developing solutions appropriate for practice for new joining technology challenges.

Moreover, we are the right partner for the fields of materials testing and corrosion protection, not only in training but also with regard to the advice for and execution of testing and corrosion protection assignments.

GSI provides you with support and advice with regard to all questions for everything to do with the subjects of materials, joining processes, testing procedures, corrosion protection as well as personnel qualification and training.

All over the world and everything from one source.

We are looking forward to you and your questions.
