Abstract: An object of the present invention is to provide a thermal spraying robot system capable of automatically determining spraying conditions according to the shape of a workpiece. Shape data on a workpiece (9) and material data on a thermal spray material are entered by operating a data input unit (1). A spray condition database 3 stores a plurality of spray parameters for kinds of thermal spray materials and for qualities of sprayed coatings. A path calculating unit (4) selects values of spray parameters from the spray condition database (3), and then calculates a path for a thermal spraying gun (14) according to a predetermined program on the basis of the shape data on the workpiece and the selected values of the spray parameters. The path calculating unit (4) decides whether or not a thermal spraying operation can be carried out by moving the thermal spraying gun along a calculated path.

Abstract: Provided are a gas turbine multi-hole film-cooled combustor liner, which can be manufactured with improved accuracy in shape and position of cooling holes in a very short time, ensuring desirable buckling strength and satisfactory cooling performance. A planar flat member is curved to form a liner shell of a cylindrical shape, the cylindrical member is welded in the longitudinal direction thereof to form a cylindrical shell. Then a wavy configuration and a corrugated configuration are formed on the cylindrical shell by a hydro-bulging method, cooling holes are formed through the liner shell by laser drilling at or near wave crest portions of the wavy configuration of the liner shell, and inner rings are attached to the liner shell by resistance spot welding or vacuum brazing.
