摘要
采用经验公式分析了09MnNiDR钢的焊接接头裂纹敏感性,研究了焊接工艺对焊接接头性能的影响。通过分析和斜Y型坡口焊接裂纹试验表明09MnNiDR具有良好的焊接性能,在室温条件焊接不会产生焊接冷裂纹。通过采用合理的焊接工艺,分别采用钨极氩弧焊、焊条电弧焊和埋弧焊焊接09MnNiDR钢,得到综合性能良好的焊接接头,能够满足工程需要。
The crack sensitivity of the welded joint of 09MnNiDR steel is analyzed by empirical formula theory,and the influence of welding technology on the welding joint performance is studied.The theoretical analysis and the Y-groove restraint weld cracking test show that the 09MnNiDR has good welding characteristics,and welding cold cracks can not appear at room temperature.09MnNiDR steel is welded by GTAW,SMAW and SAW and reasonable welding technology.Its welded joint is of good comprehensive performance.It can meet the engineering needs.
