    • PROBLEM TO BE SOLVED: To ensure a welding and fixing process of two parts of a resin case 1 and a base 2, on press-fitting faces 14 and 24 without setting a caulking allowance for preventing the size from being increased and also without the use of a dedicated pressurizing device for retrenching an assembling cost.
      SOLUTION: A dedicated pressurizing device which is required in a conventional lapped laser beam welding process and used for eliminating a gap between two parts made of a resin material can be dispensed with by forming the faces to be welded together of a side wall part 11 of the resin case 1 and a lid body part 21 of the base 2 in such a way that the faces to be welded together can be forced in. In addition, a laser beam is obliquely emitted to a press-fitting face 4, on the opening part 12 side, of the side wall part 11 of the resin case 1 from the outer peripheral side edge, on the illustrated upper end face, of the lid body part 21 of the base 2. Consequently, it is possible to weld together and fix the press-fitting face 14, on the side wall part 11, of the resin case 1 and the angular barrel-shaped force-in face 24 of the lid body part 21 of the base 2.

    • 要解决的问题:为了确保树脂外壳1和基座2的两部分在压配合面14和24上的焊接和固定过程,而不设置用于防止尺寸增加并且也不使用的铆接余量 专用的加压装置用于缩短组装成本。 解决方案:通过在传统的重叠激光束焊接工艺中需要的用于消除由树脂材料制成的两个部分之间的间隙的专用加压装置可以通过将待焊接的表面形成为 树脂壳体1和基座2的盖体部21以能够被迫焊接在一起的方式被加入。此外,激光束倾斜地向压配合面4发射,在开口 树脂壳体1的侧壁部11的外周侧边缘部分12侧,位于基座2的盖主体部21的所示上端面上。因此,可以焊接在一起并固定 树脂外壳1的侧壁部11的压配合面14和基体2的盖体部21的角筒状的压入面24。
