Abstract
A composite manufacture includes a first steel substrate, a second steel substrate disposed in contact with the first steel substrate to define a faying interface therebetween, and a spot weld joint penetrating the first steel substrate and the second steel substrate at the faying interface to thereby join the second steel substrate to the first steel substrate. The first steel substrate has a heat-affected zone adjacent the spot weld joint having a boundary, wherein the boundary and the faying interface define an angle therebetween of greater than about 75°.
