In 1997 the numerous works of equal standard led to a division of the prize between two prizewinners.
The prize-winning work:
The development of a rotation torch in connection with a high dissipating welding head guidance system.
This invention developed by Dr.-Eng.Martin Oster, owner of the engineering and planning office MECOS in Wilnsdorf/Rudersdorf, opened new opportunities of application for automatic welding systems which will, at the same time, also lead to a reduction in production costs. The high-speed rotating inert-gas welding torch permits the circular deflection of the wire-electrode tip with frequencies to over 80 Hz, due to the movement of the torch on a conical sleeve. The water-cooled torch nozzle assembly guarantees 100% duration of activation. The rotary torch will fulfill sensory tasks which could not be realized so far. In connection with the impulse arc welding technology, a process is now available which achieves a targeted drip solution and a signal detection synchronous to the torch position at the deflection on the joint. This means that a welding head guidance system is realized also with materials of high conductivity and during the welding of thin overlapping flaps.
The development of a new type of arc welding procedure for joints of non-circular steel plated dividers in one working operational process. The new plate welding system with stroke ignition, developed by the engineer, Franz Peter Hirschmüller in cooperation with the engineer, Dr. Andreas Nentwig, reduces the working time and prevents crevice corrosion problems. With this procedure, thin, non-circular sections with a thickness of 0.8. to 3 mm can be surface-welded in one working process, by means of line and areal contact operation. Welding times of approx. 1s can be achieved at welding currents up to 2000 A. The welds are virtually non-defective and attain extremely high tensile strength. Complicated working runs such as tacking or welding through brackets will no longer be feasible. The retrofitting of brackets and welding components will now be possible, which will lead to a remarkable weight reduction. Innovative constructive and manufacturing solutions will be opened, also in the field of automatic welding.
