SYSTEM AND METHOD FOR REDUCING WELD ROOT CONCAVITY |
摘要 |
A method of controlling a back weld root surface includes arranging a sealing portion along the back weld root surface of a workpiece to form a purge region adjacent to a section of a joint, supplying a shielding gas within the purge region at a first flow rate, and applying a weld deposit across a front surface of the section of the joint. The shielding gas displaces an ambient environment within the purge region, and the back weld root surface of the weld deposit includes a positive root penetration relative to the back weld root surface based at least in part on the shielding gas within the purge region. |

1. A method of controlling a back weld root surface, comprising:
arranging a sealing portion along the back weld root surface of a workpiece to form a purge region adjacent to a section of a joint; supplying a shielding gas within the purge region at a first flow rate, wherein the shielding gas displaces an ambient environment within the purge region; and applying a weld deposit across a front surface of the section of the joint, wherein the back weld root surface of the weld deposit comprises a convex root surface with a positive root penetration relative to the back weld root surface based at least in part on the shielding gas within the purge region. |
