Abstract
A system, apparatus, or method for joining components is provided. The system applies force along an axis, with a friction pin, to a first substrate, such as with a joiner or joining apparatus. The system also frictionally melts a portion of the first substrate adjacent the friction pin by rotating the friction pin about the axis at a first speed within the first substrate. The system also applies force to the second substrate along the axis and frictionally melts a portion of the second substrate adjacent the friction pin by rotating the friction pin at a second speed within the second substrate. The system embeds a portion of the friction pin within the first substrate and the second substrate. In some configurations, the first speed and the second speed are substantially equivalent. In other configurations, the first speed is different from the second speed.
