摘要：
PROBLEM TO BE SOLVED: To provide a welding joint of a fuel tank 3 wherein the welding of an outer layer material with the fuel tank is not hindered by the melted resin of the inner layer material when a melted part is welded to the fuel tank in making the melted part into the laminated structure of an inner layer material using a resin alloy material obtained by making denatured HDPE with EVOH to alloy with the outer layer material using the HDPE resin.
SOLUTION: In the welding joint 12 having a cylindrical part 16 and the melted part 18, the melted part 18 is made to be the laminated structure of the inner layer material 36 using the resin alloy material with the outer layer material 38 using the HDPE resin, and a melted end surface 38A of the outer layer material 38 is projected further to the fuel tank 10 side than a melted end surface 36A of the inner layer material 36 so as to make a step between them before heat welding.

要解决的问题：提供一种燃料箱3的焊接接头，其中当将熔化的部件焊接到内部材料时，外层材料与燃料箱的焊接不会受到内层材料的熔化树脂的阻碍 使用通过使用HDPE使具有EVOH的变性HDPE与外层材料合金而获得的树脂合金材料将熔融部分熔化成内层材料的层压结构的燃料箱。 解决方案：在具有圆筒部16和熔融部18的焊接接头12中，使用外层材料38的树脂合金材料，使熔融部18成为内层材料36的层叠结构，使用 HDPE树脂和外层材料38的熔融端面38A比内层材料36的熔融端面36A进一步向燃料箱10侧突出，以在热焊接之前形成台阶。 版权所有（C）2007，JPO＆INPIT
