A welded joint for structural component having two or more portions fused together at a weld line. An adhesive layer is placed between the two or more portions at the location of the weld line and a conductor is placed between the two or more portions in operable contact with the adhesive. Energy is transmitted through the conductor and into the adhesive layer to activate the adhesive layer and create the weld line that defines the welded joints between the two or more portions. The welded joint of the structural component allows energy to be injected into the adhesive layer via the conductor in order to cause the adhesive layer to activate from the inside of the adhesive outward. The conductor can be placed adjacent the adhesive layer or within the adhesive layer in order to cause the adhesive to be activated from the inside outward.
