Popis: In this work, the parameters of explosive welding of plates and pipes from heat resistant alloys with high-strength steel were established. It was found that to ensure strong adhesion, it is necessary to increase the kinetic energy of a flayer plate made of a heat-resistant alloy several times in comparison with the explosion welding of steel sheets. Metallographic studies have shown that at similar modes of explosion welding in cylindrical products, the number of cast inclusions is significantly increased compared to sheets up to the appearance of a continuous layer at the weld interface. Mechanical tests have confirmed the quality of the joint. This material is promising for work in structures experiencing thermal and erosive effects.
