<p>In a method of joining a pair of metal parts, one of the parts is provided with an insulative coating at its surface to be joined to the other part, while the forming surface of the other part is free of any coating and defines a plurality of substantially parallel, longitudinally extending splines. To effect the required join, the joining surfaces of the parts are urged into interengagement and are simultaneously caused to undergo relative vibrational movement in a direction substantially parallel with the splines on the other part whereby, on termination of the vibration, a welded joint is produced between the parts.</p> |
