对高强管线钢,在焊接作业中由于焊接峰值温度的不同,焊接热影响区所表现出来的组织特性和性能将会有所差别,以X80管线钢为例,通过焊接热模拟试验分析了在不同焊接峰值温度和线能量下,试验钢的组织变化和峰值温度对材料硬度、冲击韧度的影响。
For high strength pipeline steel, due to the difference of peak welding temperature, the microstructure and properties of HAZ will be different. Taking X80 pipeline steel as an example, Under the peak welding temperature and the energy of the wire, the influence of the microstructure and the peak temperature of the test steel on the hardness and the impact toughness of the material was investigated.
