A member (42, 46, 48) is secured to a supporting surface (44) by a peripheral seam weld (52) that partially closes off an area between the member and the surface. In the region of the or each interruption in the continuity of the seam weld, there is provided between the member (42, 46, 48) and the supporting surface (44) an insert (56) of a material that is stable in shape at normal temperatures but that has expanded and flowed at elevated temperature, e.g. due to heating by the welding process, to complete the sealing of said area between the member and the surface, in cooperation with the seam weld. |
