The possibility of explosion welding of plates and disks made from low-ductility oxide dispersion-strengthened steel was studied. In order to prevent appearance of cracks on the surface of the plates, low-temperature (up to 200°C) heating was applied to the flyer plate. In a wide range of explosion welding parameters with reference to the weldability window, the microstructure of the resulting joint is shown for 2 mm thick and 50 mm diameter discs that were laser welded into carbon and stainless steel plates. A tensile strength test of the produced joints was conducted. It was possible to achieve a joint strength of 75 % of the strength of the base metal. Explosion welding of 100x50x3 mm plates was performed; the joint zone boundary has a wavy shape typical for explosion welding. The chemical composition of inclusions in the joint zone was determined, using energy dispersive X-ray spectroscopy, and it was established that silicates are present in the joint zone. It is shown that application of low-temperature heating allows welding plates from ODS steel using the explosion energy. 14 Ref., 3 Tabl., 9 Fig.
