    摘要： Method and apparatus for splicing together metal webs (26) with the ends thereof being butted against each other or slightly lapped on each other. In the metal web splicing apparatus, there is provided a reduction roller (12) which comprises a hold portion (12A) having a first radius and a projected portion (12B) having a second radius slightly greater than the first radius. With use of the reduction roller (12), while both sides of the weldedly spliced portion of the metal webs (26) are being held and fixed by the hold portion (12A) of the roller (12), and weldedly spliced portion is rolled by the projected portion (12B) of the roller (12), thereby preventing escape of the rolled portion.

    摘要： The flash removal unit presented herein is suitable for a friction stir welding (FSW) head and includes a blade (414) and an annular body (411). The blade (414) removes flash created by a FSW tool during FSW operations. The annular body (411) defines a flash capture area (FA) around the blade (414) and is configured to at least temporarily retain the flash removed by the blade within the flash capture area. The flash removal unit may also define a flow path (FP) along which the flash can be suctioned away from the flash removal unit.

    摘要： Provided are a magnetic rotating arc joining method that can suppress occurrence of joint defects with a simple configuration and a joint unit in which joint defects are suppressed. A joint unit (10) includes a first metal pipe (21), a second metal pipe (22), and a joint portion (a region including a joint interface (11)) at which the end faces of the first and second metal pipes are joined to each other. At the joint portion, an outer circumferential bead portion protruding toward the outer circumference side and an inner circumferential bead portion (13) protruding toward the inner circumference side are formed. The difference between the width of the outer circumferential bead portion (the width L1 of a grinding portion (12)) and the width L2 of the inner circumferential bead portion (13) in a direction from the first metal pipe (21) toward the second metal pipe (22) is equal to or smaller than 40% with respect to the average value of the width L1 of the outer circumferential bead portion and the width L2 of the inner circumferential bead portion (13).
