ABSTRACT:
Aluminum is joined to titanium by welding using so much welding energy that the temperature on the titanium side of the alloying melt boundary remains below 2000.degree. C., while titanium and aluminum do, however, melt at the joint interface.
In a weldment thus obtained, the base material alloys and aluminum filler of which contain at maximum 10% titanium, there is in the vicinity of the interface between titanium and aluminum only a discontinuous .beta.-phase, dispersed in the aluminum matrix.
