FRICTION STIR WELDING AS A RIVET REPLACEMENT TECHNOLOGY |
| 摘要 |
<p>The present invention provides an improved method and apparatus for joining aluminum allow panels (eg. 2090-T83 aluminum lithium alloy). The method preliminarily positions two panels and skin panels next to each other so that a stringer panel overlaps a skin panel. A friction stir weld pin tool penetrates through one panel and at least partially into another panel. The panel material around the pin tool is frictionally heated.</p> |
