New welding technology at Fastner

To maintain process reliability also for large volume production, we have invested in the technology of friction stir welding (German: Rührreibschweißen).

A rotating tool heats the light metals to just below the melting point while stirring the materials into each other. Advantages are in addition to the high stability and the even seam surface the slight welding warpage as well as the reduction of pores and cracks in the weld seam.

Possible fields of application for this welding procedure are cooling and heating plates, cylinder heads, heat exchangers as well as tool and battery coolings. In addition, this joining technology is very well received in (railway) vehicle construction, medical and plant engineering as well as in the food and electrical industry.

Responsive and in English into the New Year

At the turn of the year, we have once again updated our homepage by optimizing it for smartphones and tablets. Furthermore, is as of now also available in English.

Mobil in deutsch

In this sense, the whole Fastner team wishes you all a successful and healthy year 2015!
