Abstract:	The properties of TC1 / 1060 / 6061 Ti/Al explosive composite tungsten argon arc welding dissimilar welded joints were analyzed by means of SEM, EBSD, XRD and EDS. The results show that the microstructure of the weld changes from coarse β grains to lamellar martensitic α' phases. There is an appropriate amount of mutual diffusion of titanium/aluminum atoms at the welding, indicating that there is a strong interatomic bonding force in the weld. There are no titanium and aluminum intermetallic compounds produced in welds, but exists Al/Fe and Al/Mg compounds, indicating that the bonding quality of the weld is lower than untreated. The weld may become a point of stress concentration in the joint which affects the bearing capacity of joint. The composite welding specimens have strong tensile properties and poor shear properties.
