ABSTRACT
The influence of both the conditions of electron beam welding of heat-resistant steels 10Kh12M and 10Kh9MFBA 30 mm thick without preheating and also the spatial arrangement of electron beam relatively to the part being welded on weld formation and tendency to crack formation was investigated. It was established that in EBW of the mentioned heat-resistant steels without preheating the elimination of cracks and elongated cavities is achieved at the speed of welding of not more than 3 mm/s. The reproducibility of quality welds and formation of narrow and deep welds with parallel walls of cast zone is possible by application of technological scanning of electron beam around the circle and elliptic trajectory, and also arrangement of electron beam focus at the level of 2/3 of the specimen thickness. In the development of EBW technology of heat-resistant steels the non-destructive method of ultrasonic testing can be recommended for application.
