摘要： PROBLEM TO BE SOLVED: To provide a friction pressure welding method by which the plug part of a first member and the hole part of a second member are joined with high reliability.
SOLUTION: The plug part 11a of a first member 11 is inserted and butted into the hole part 12a of a second member 12. The first member 11 and the second member 12 are relatively rotatively moved at the butted faces while pressurizing the first member 11 and the second member 12, and, by the generated friction heat at the butted faces, the first member 11 and the second member 12 are welded. When the plug part 11a of the first member 11 is inserted into the hole part 12a of the second member 12, the initial butted position P between the outer circumferential face of the plug part 11a and the inner circumferential face of the hole part 12a is decided as the central part in the axial direction of the hole part.

摘要： PROBLEM TO BE SOLVED: To provide laser welding equipment where a nozzle is shortened, and to provide a welding method.
SOLUTION: In the laser welding equipment 1, a laser irradiation port 22 irradiating a weld zone with a laser beam 81 heating metal, and gas injection ports 24 and 26 surrounding the laser irradiation port 22 are formed. The laser welding equipment 1 is equipped with an inner nozzle conical part 19 dividing the laser irradiation port 22 and the gas injection port 24, and also, a hole 44 is formed at the inner nozzle conical part 19. The gas injection ports 24 and 26 inject shielding gas to be fed to the weld zone, and also, the laser irradiation port 22 jets gas flowing through the hole 44 from an outside gas passage 25. At this time, in the shielding gas fed to the gas injection ports 24 and 26, the turbulence of the flow is reduced, and further, the gas made to flow from the laser irradiation port 22 prevents the intrusion of fume generated at the time of welding to the laser irradiation port 22. Thus, the laser welding equipment 1 has no need of elongating a nozzle for straightening the flow of the shielding gas , thus enabling to shorten the nozzle.

摘要： PROBLEM TO BE SOLVED: To execute efficient and uniform roughening free from deterioration in the characteristics of the material to be applied with coating by executing roughening treatment using a laser beam to the surface of a hard inorganic material as a surface layer, particularly, on the surface of a material with a crystal structure having covalent bondability to form coating by a thermal spraying method. SOLUTION: Prior to the formation of coating on a surface layer composed of a hard inorganic material, the surface of the material to be subjected to coating (hard inorganic material) is subjected to roughening treatment. In accordance with the degree of the objective roughening, the spot diameter, focal distance, pulse frequency or the like of a laser beam 5 are regulated, which is applied to the surface layer 2 of the material to be subjected to coating, and boring or grooving is executed. Substantially, it is applied to the one in which a surface layer composed of a hard inorganic material such as Sic, TiC, TiN, HfC or the like is formed on a material composed of a hard inorganic material such as Sic, TiC, HfC or the like, or a WC/C composite material or a base material such as graphite or the like.
