Abstract
A multi-pass friction stir weld joint and method for forming such joints are provided. The multi-pass weld joint is formed of at least first-pass and second-pass friction stir weld joints that are disposed in the workpiece in a substantially parallel configuration. The first- and second-pass joints define transversely opposite advancing and retreating sides, and the second-pass joint is disposed to at least partially overlap the retreating side of the first-pass joint. Thus, at least some of the material of the workpiece in the first-pass joint is processed during the formation of the second-pass joint.
