We are working on the industrial application of friction stir welding (FSW) since 1995, two years after it had been invented by Wayne Thomas at TWI Ltd in the UK. We focus on implementing the process industrially, by demonstrationg the feasibility on existing machines before specifying a suitable production machine.
The following industrial implementations of FSW are based on our consultancy (in chronolgical order):
Based on the experience gained in thes Projects, we started to work in management:
After the development and successful marketing of EMPT machines (electromagnetic pulse technology for welding and forming) and MIG/MAG welding robots, we are now working again on friction stir welding:
Based on the experience gained in these projects and functions, we are in a unique position to provide you with reliable consultancy.
In 2019, Stephan Kallee could look back on 25 years of membership in DVS - Deutscher Verband für Schweißen und verwandte Verfahren e.V. (German Welding Society). For this reason, he was honoured on various occasions.
On the occasion of the annual meeting of the DVS within the Great Welding Conference in September 2019, the honouring of the long-standing membership was announced. In addition, the personal appreciation was made by the District Association Rhine-Main in a ceremony.
