WELDED EXCAVATOR BOX SECTION ARM AND METHOD OF FABRICATION |
| 摘要 |
A box-section arm (16) of an excavator or the like has a pivot axis (19) at one side. Two flat plates 25, 26 close the underside of the box-section adjacent the pivot axis, and are welded transversely from a pair of projections 28, 29 at one side, to corresponding pair of projections 28, 29 at the other side. The projections 28, 29 are partially but not wholly removed after welding. |
