| Abstract: |
| This paper analyzed the welding performance and the mechanical performance of the low-alloy high-strength steel HG785D. The data show that the excellent mechanical performance of the welded-seam can be realized by using the reasonable weld technology and criterion, adopting mixed-gas（80％Ar+20％CO2）shielded welding and choosing Wuhan Anchor welding wire of Φ1.2WH80-G. And it obtained favorable effect in the practical application. |
