摘　　要：对国产F92钢焊接热影响区的粗晶区进行热模拟试验。不同热处理条件后试样的硬度试验,冲击韧性试验和组织分析表明,焊后热处理对改善焊接接头的塑韧性具有显著作用。焊接工艺试验表明,国产F92钢存在一定的冷裂倾向,实际生产宜采用多层多道焊,层间温度的控制也很重要。The domestic steel F92 HAZ of coarse-grained zone hot simulation test. Different heat treatment conditions of sample hardness test, impact toughness testing and organizations analysis indicates that, the post-weld heat treatment have a significant role in improving the toughness of welded joints of plastic. Welding procedure tests showed that, there is a certain tendency to cold cracking for Chinese-made steel F92. The actual production should adopt the multi-storey multi-channel welding, inter-layer temperature control is also very important.
