    Abstract: A second member is made of a material difficult to be welded to a first member. A first step includes forming a third member by welding a first filler material to the first member through a through-portion of the second member. A second step includes forming a fourth member by covering a surface of the third member with a second filler material and welding the fourth member to the second member.

    Abstract: A transmission fiber includes a first core and a second core. The second core is provided on the outer periphery of the first core. In a first step of a laser termination process, a first laser beam is emitted from the second core, and a second laser beam is emitted from the first core. In a second step, the output power of the second laser beam is gradually reduced while a position at which the first laser beam and the second laser beam are emitted to a workpiece is moved in a laser processing direction. In a third step, the output of the second laser beam is stopped while the first laser beam is emitted from the second core.

    Abstract: A second member has a through-portion penetrating toward a first member. An overlapped surface of the second member with the first member includes a recess. The recess is recessed so as to surround an entire periphery of the through-portion. The recess is provided with a sealing material. The sealing material closes a gap between overlapped surfaces of the first member and the second member.

    Abstract: A laser welding method of the present disclosure includes a first step, a second step, and a third step. In the first step, a first workpiece and a second workpiece are stacked on each other. Each of the first workpiece and the second workpiece has a surface coated with a first material and is made of a second material, which is different from the first material. In the second step, a first region in which the first workpiece and the second workpiece are stacked on each other is irradiated with a laser beam so that the laser beam penetrates both the first workpiece and the second workpiece. In the third step, a second region including the first region is irradiated with a laser beam in a spiral fashion.
