Weldthermalcycle simulation was used to reproduce the structure in the HAZ of single run and multi-layer welding.
采用焊接热模拟再现了单道焊和多层焊haz的组织。

The influence of welding thermalcycle on structure and properties in grain-coarsening region of X80 pipeline steel was investigated by weldthermal simulation technique and the charpy test.
采用焊接热模拟试验和冲击试验,研究了X80管线钢焊接热循环对粗晶区组织性能的影响。

The toughness of weld metal is the highest while the coarse grained region in the HAZ is the lowest because of welding thermalcycle and formation of brittle microstructure.
