Abstract

A friction stir welding method including: feeding a filler material through a first passage in a friction stir weld tool and into a substrate during friction stir welding of the substrate; and rotating the filler material with respect to the substrate while feeding the filler material. In this method, heat generated by rotational frictional contact of the filler material contributes to plasticization of the filler material.
