The friction welding of a dissimilar-metal joint in titanium and tungsten pseudoalloy, in which sintered tungsten grains and alloy Ni–Fe formed respectively the matrix (W-95 wt.%) and the bonding phase, was investigated. The aim of the investigations was to determine which microstructures occur in the titanium–tungsten pseudoalloy joint and which interlayers ensure that there are no brittle structures in it. The friction welding process was found to proceed differently than in the case of titanium–tungsten joints. Stable Ti–Fe–Ni–W intermetallic phases with cracks propagating in them would occur in the joint zone. Proper interlayer of copper on the tungsten pseudoalloy side and vanadium on the titanium side were selected. Joints with tensile strength of 410 MPa were obtained.
