Abstract: A method to join a first enclosed workpiece and a second enclosed workpiece is provided. The first enclosed workpiece includes a first connecting end and a first cavity region. The second enclosed workpiece includes a second connecting end and a second cavity region. A backing member is placed in the first connecting end, with a first end within the first cavity region. A resilient member is positioned in the first cavity region, with a first portion within the first cavity region. The second enclosed workpiece is positioned proximal to the first enclosed workpiece to define a gap between the first connecting end and the second connecting end. Upon positioning, a second end of the backing member and a second portion of the resilient member are placed within the second cavity region. The first connecting end is then welded with the second connecting end over the backing member near the gap.

Abstract translation: 提供了一种连接第一封闭工件和第二封闭工件的方法。 第一封闭工件包括第一连接端和第一腔区。 第二封闭工件包括第二连接端和第二腔区。 背衬构件放置在第一连接端中，第一端部位于第一空腔区域内。 弹性构件定位在第一空腔区域中，第一部分位于第一空腔区域内。 第二封闭工件位于第一封闭工件的近侧，以限定第一连接端和第二连接端之间的间隙。 在定位时，背衬构件的第二端和弹性构件的第二部分被放置在第二空腔区域内。 然后将第一连接端与间隙附近的第二连接端焊接在衬垫构件上。
