TRIAXIAL WELDABILITY WINDOWS ON EXPLOSIVE CLADDING OF DISSIMILAR METALS
Keywords:
Explosive Cladding, Dissimilar Metals, Weldability Window, Microstructure , MicrohardnessAbstract
Explosive Cladding is a unique combination of explosive and metallurgical technologies. By detonating an explosive charge on top of a plate, the plate can be bonded with an underlying plate. The explosive detonation provides the energy to form a jet between the plates that cleans the surfaces and subsequently bonds the two plates metallurgically. An attempt is made to generate three dimensional welding window using empirical relations. Aluminium to Low carbon steel sheets is explosively cladded and the experimental results were found to be in accordance with the generated weldability window. The increase in hardness near the interface is also reported.
