A jointing apparatus comprises a first laser head which emits a laser beam for adhesive heating and a second laser head which emits a laser beam for welding. In jointing components of a work with a thermosetting adhesive agent, the defocused laser beam is applied to an adhered part for a short time. Thereupon, the adhesive agent is primarily cured so that the components are tacked together. In spot-welding the components, the laser beam for welding that is converged by means of the second laser head is applied to a spot-welded joint.
