Hans Hornig

from Wikipedia, the free encyclopedia

Hans Hornig (born September 11, 1951 ; † September 23, 2009 at Forstinning ) was a graduate engineer, specialist welding engineer and head of the welding and joining technology group at BMW for 15 years .

Hans Hornig was one of the laser pioneers in car body construction. Right from the start, he pursued product and productivity improvements through the targeted use of laser material processing in order to achieve cost and quality targets.

As early as 1986 he was responsible for the first large-scale application of laser welding from the roof skin to the side frame of the BMW 3 Series Touring models. After that, laser welding was successfully further developed for the 5 series. By 2001, almost twelve million meters of weld seam were reliably produced in the BMW body shop. He also used laser beam welding for aluminum, for example the push panels welded together from deep-drawn sheet metal shells for the 3-series. For overlap seams made of galvanized sheet metal as visible seams in the sill area, his team developed a flexible system that had an 8 kW CO 2 laser beam source, a flexible beam guidance system, a welding head with an optical sensor and a robot to guide the welding head.

He developed a modification of laser brazing on tailgates and body roofs for the BMW 5 series. With the coaxial soldering head developed jointly by BMW and Mitsubishi, the wire was fed coaxially to the direction of the laser beam, so that the laser beam and solder wire hit the solder joint in the same position and direction. The melting of the solder wire and the heating of the joint on three-dimensional soldering contours became process-reliable and the soldering result was of high quality.

He showed an exemplary interest in interdisciplinary cooperation with other companies and had a unique position in the laser technology working group in particular.

He died in a nocturnal car accident after colliding at high speed with a truck that was properly parked in a motorway parking lot for unknown reasons.
