Abstract
A method and apparatus is disclosed for obtaining an improved bond between two structural members. Spherical particles, preferably graded steel shot, are interspersed within the adhesive and move in sliding and rolling contact relative to one another to establish an accurate space between opposing face surfaces of the structural members as the structural members are brought into pressured contact with one another. An induction coil may then be used to accurately heat the spherical particles and thus establish a heat source to thermally set the adhesive from within the spaced gap between the structural members established by the spherical particles.
