| Abstract: |
| Aimed at the quality problem of bellows which used traditional welding technology, the EBW research of large diameter bellows with inside assemble joint was carried out. The primary research items include cooperative turning before welding, work fixture design, precise assemble, welding path planning, electron beam welding, and the controlling of welding deformation. The product welding quality satisfied with the requirements and set an example of welding application on large diameter-thin wall products. |
| Key words: large diameter bellows vacuum EBW integrally inside support device |
