The article presents the results concerning the development of a technology combining laser welding and hybrid surfacing enabling the making of butt joints in composite tube grades Sanicro 38/4L7 and 3R12/4L7. The tests involved the determination of the parameters of the laser welding of tube grade 4L7 and the hybrid surfacing of the external layer of tube grade Sanicro 38 and 3R12. The article also presents the results of the macro and microscopic tests of the joints.
