The Gesellschaft für Schweißtechnik International mbH (GSI) was founded 1999 from the DVS - Deutscher Verband für Schweißen und verwandte Verfahren e.V. through the integration of four Schweißtechnische Lehr- und Versuchsanstalten (SLV).

The GSI works, as a non-profit Ltd, neutral for individuals, handicraft businesses, industry companies, public agencies and research bodies. She is an association of efficient welding technology institutions with over 80 years of experience in joining, cutting and testing technologies. The goal of the GSI mbH is the education, the consultation as well as the technology transfer in Germany and abroad.

The GSI mbh is operating in the fields of education, consultation, expert reports, research, development and testing. With its long-standing experience the GSI mbH guarantees a high level of compentencies in the fields of joining, cutting and testing technologies.

What means the non-profit status? Are we, as a welding education and technology institute, funded by the government?

The GSI mbH, Branch SLV Munich is a non-profit institute without fixed funds by public authorties. The charitable nature arises from the theoretical and practical education and training. With our manifold activities we still have to consider economical aspects, to cover the costs involved.

The departments quality assurance, material technology as well as the research and technolgy are part of the economic business operations.

When was the company founded?

The SLV Munich was founded in 1950 by the German Association for welding Technolgies (today: DVS - Deutscher Verband für Schweißen und verwandte Verfahren e. V.) to promote the development and application of welding technologies charitable, company neutral and financially independent.

What is the value of welding technogies?

Welding technolgy is a link between a lot of technical fields. It is used everywhere to join, coat or separate parts. A lot of constructions and production processes are only possible because of it. The welding technology uses manifold techniques and energy sources. It intervenes with the structure of the materials, because it melts or deforms the material. It has high requirements to the planning, executing and testing experts.

The welding seam is a joining element of high quality, but also with a high danger for errors. Because of this question of quality assurance are a high priority for the value of a whole building.
