Abstract

The strength of the welded joint of the pipe and the collector made of 12Kh1MF steel are investigated within the framework of the model of elastic solid, taking into account their real geometry and the dependence of the material characteristics on temperature. Zones of maximum operating stresses in the joint for different types of welding are identified. Design and technological solutions aimed at significant reducing the maximum operational stresses are proposed.
