Totally worn-out impellers and vital parts of rock and chemical processing machinery proved a draw at the Vautid stand.

The hardfacing specialist produces a range of wear- resistant materials ranging from chromium carbide welding rods to special castings and tough plastics. The business has its origins in work by founder, Dr Ing Hans Wahl, who worked on development of a coal dust compression ingnition engine in the 1930s.

Wear from the burned coal particles and impurities proved to be a huge obstacle for these piston engines which were not able to compete with conventional steam turbine power stations. But the hardfacing technology survived and Wahl founded Vautid in 1945 to develop the materials.

Vautid-100 chromium/carbon material is now avialable as stick electrodes, flux cored wire, continuous cast rods and as metal powder for sprayed application.
