摘要
对E71T-1药芯焊丝焊接Q345C钢进行了试验研究,分析了焊接接头和热影响区的力学性能、金相组织。结果表明,采用E71T-1药芯焊丝进行焊接,焊缝及热影响区的冲击韧性没有明显差别,焊缝性能良好,而且可以提高焊接效率。
An experimental study on the use of E71T-1 flux-cored wire for welding of Q345C steel was conducted to analyze the mechanical properties and metallographic structure of the welded joint and heat= affected zone. The results show that when welding with E71T-1 flux -cored wire, there is no significant difference in impact toughness between welding seam and heat -affected zone while the welding seam has high performance and the welding efficiency can be improved.
