ABSTRACT The purpose of the experimnetal setup was to study the materials used in the manufacture of die-casting tools and of surfacings produced in repair welding of the tools subjected to thermal fatigue. The device permitted the execution of repeated cycles of test specimen heating in liquid aluminium and their quenching in a cooling emulsion. The test specimens were additionally water cooled in the inside, which produced a periodical increase in thermal stresses in the test specimen. Decisive for the material quality were the number and size of cracks in the test specimen occurring after a certain number of cycles.
