Welding studies were conducted on boron-aluminum BAl composites to observe the effects of gas-tungsten arc fusion welding on the boron reinforcing filaments and aluminum matrix. The objective of this investigation was to determine the basic potential of fusion welding BAl composites for possible structural applications. Microstructural observations after welding revealed matrix fusion without apparent boron filament damage. Analysis of weld metal regions indicated that aluminum filler metal additions intermixed with the matrix and altered its chemical composition. It is concluded that fusion welding of BAl composites may be possible by control of welding energy input.
