METHOD FOR REMOVING BRITTLENESS AND STRESSES FROM WELDED STEEL PIPES |
| 摘要 |
<p>Brittle fracture in weld steel pipe structures having a seam adjacent a butt weld is substantially eliminated by arc remelting to form a bead of weld material over the seam; this is found to increase the toughness, eliminate weld defects and relieve residual tensile stress in the circumferential direction.</p> |
