Description
Summary:This paper deals with cracks in an electron beam welded joint made of severely different materials. The motivation is to improve the design and reliability of an electron beam welded worm wheel, which may contain large cracks due to hot cracking. Material properties of the weld zones were determined by minitensile specimens. The fracture behaviour of the weld was investigated with CTS- and SENB-specimen. So far, estimates of the threshold values for the fatigue crack growth can be presented. Further experimental and numerical investigations are planned. [Materials: bronze and steel.]
