Japan Atomic Energy Research Institute (JAERI) has studied manufacturing processes of radial plates used in Toroidal Field coils of the International Thermonuclear Experimental Reactor (ITER). A manufacturing procedure, in which grooved radial plate blocks are connected by laser welding, was considered as the most rational one. A trial fabrication of a radial plate which has the same dimensions of the actual ITER was performed to clarify the feasibility of this procedure through the measurements of deformation during machining and welding. As a result, it was concluded that this manufacturing procedure could be used for the ITER because it could achieve the required tolerances for manufacturing of the radial plates
