ABSTRACT:
A welding method forms a fiber reinforced weld in a fiber metal matrix composite. Novel weld rods or consumable electrodes for introducing the fibers to the molten weld pool are disclosed. Reinforcing fibers are added to a molten weld pool that is initially substantially free of fibers. The fibers strengthen the weld. The concentration of the fiber should be controlled so that the viscosity of the pool remains suitable for welding.
