レーザ光伝送用光ファイバ及び溶接方法
Document Type and Number:
Japanese Patent JP6715815
Kind Code:
B2
Abstract:
To provide an optical fiber for laser beam transmission in which getting dirty of a weld zone can be suppressed.SOLUTION: An optical fiber 10 for laser beam transmission comprises: a welding core 11 which has polygonal cross-sectional shape, emits laser beam for performing braze welding in which the beam is irradiated along welding scheduled parts of first and second metal materials; and a plating removing core 12 which has circular cross-sectional shape, is provided to emit laser beam for removing metal plating and irradiated along at least either one of the welding scheduled parts of the first and second metal materials not subjected to the braze welding, when irradiating the laser beam emitted from the welding core 11 along the welding scheduled parts of the first and second metal materials to perform the braze welding.SELECTED DRAWING: Figure 1
