In addition to welding steels of different grades together, it is now also necessary to join copper, brass, bronze to steel; titanium to aluminium, copper, steel; aluminium alloys to steel, copper, beryllium; refractory metals - niobium, molybdenum, tungsten to steel and with each other, etc. 'Exotic' combinations of metals: palladium to steel, uranium to titanium, beryllium to copper, silver to steel, gold to Kovar, aluminium, etc. are also welded. Special attention is given to the conditions of formation and development of inhomogeneities in the fusion zone of dissimilar metals, diffusion processes, wetting and spreading at the interface. The dependence of the strength and ductility properties of welded joints on the extent and nature of inhomogeneities is shown.
