摘要： PROBLEM TO BE SOLVED: To provide a laser beam machining head capable of easily and finely adjusting the injection pressure of a laser beam machining gas, and to provide a laser beam machining method.
SOLUTION: The laser beam machining head 1 comprises a nozzle part 10 and flow passages 20, 22. When a dry air GB is fed to the flow passages 20, 22, the dry air GB flows in the flow passages 20, 22 to generate the negative pressure. An inner chamber 11 of the nozzle part 10 is communicated with middle portions of the flow passages 20, 22 via communication passages 32, 34, and a shield gas GA in the inner chamber 11 is sucked into the flow passages 20, 22 by the generated negative pressure. As a result, the injection pressure of the shield gas GA at an injection nozzle 12 is dropped. When the flow passage of the dry air GB is changed, the volume of the shield gas GA sucked into the flow passages 20, 22 can be changed, and the injection pressure of the shield gas GA at the injection nozzle 12 can be changed.

摘要： PROBLEM TO BE SOLVED: To provide a laser beam welding apparatus and a laser beam welding method capable of reducing the surface roughness of a weld bead. SOLUTION: The laser beam welding apparatus is provided with a welding head 1. The welding head 1 applies the first laser beam L1 to a workpiece W to be welded to form a molten pool M, and applies the second laser beam L2 to the molten pool M. By applying the second laser beam L2, the molten pool M which is being solidified after the forming can be re-melted. Since the quantity of the second laser beam L2 is smaller than that of the first laser beam, only a portion relatively close to the surface out of the molten pool M can be re-melted. Accordingly, since the welding head 1 is movable in the direction of an arrow A, the surface shape of the molten pool M can be continuously trimmed without affecting a depth direction. Thus, a weld bead having a smooth surface can be formed. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：提供能够降低焊道表面粗糙度的激光束焊接装置和激光束焊接方法。
解决方案：激光束焊接装置设置有焊接头1.焊接头1将第一激光束L1施加到待焊接的工件W上以形成熔池M，并将第二激光束L2施加到通过施加第二激光束L2，可以再次熔化在成形后被固化的熔池M. 由于第二激光束L2的量小于第一激光束的量，所以只有相对靠近熔池M的表面的部分再熔化。因此，由于焊接头1能够沿箭头A的方向移动，所以可以不影响深度方向来连续地修整熔池M的表面形状。因此，可以形成具有光滑表面的焊道。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method for joining metallic materials, which is executable regardless of the shape of a weld line or the size of a working space, and to provide a filler used for the method. SOLUTION: In the method for joining metallic materials, along an intersection line L1 between a plane including an outer wall surface 10b of a side wall 10 of a side beam 1 and a plane including an outer wall surface 20a of a wall part 20 of a transverse beam 2, an annular filler 4, which is beforehand formed corresponding to the shape of the weld line L1, is arranged. Thereby, when joining the side beam 1 and the transverse beam 2, only a space for establishing a beam path to a filler 4 is required. The beam path is easily established by adjusting an optical system. Therefore, even when welding a narrow region or welding a weld line having a complicated shape of a closed curve or the like, the side beam 1 and the transverse beam 2 are adequately joined.

摘要翻译：要解决的问题：提供一种用于接合金属材料的方法，其可以不管熔接线的形状或工作空间的大小而可执行，并且提供用于该方法的填料。解决方案：在用于连接金属材料的方法中，沿着侧梁1的侧壁10的外壁表面10b的平面和包括侧壁1的外壁表面20a的平面之间的交线L1 设置有横梁2的20°，与焊接线L1的形状预先形成的环状填料4。因此，当接合侧梁1和横梁2时，仅需要用于建立到填料4的梁路径的空间。通过调整光学系统容易地建立光束路径。因此，即使焊接狭窄的区域或焊接具有复杂形状的闭合曲线等的焊接线，侧梁1和横梁2也适当地接合。版权所有（C）2009，JPO＆INPIT
