摘　　要：对超细组织微合金结构钢在不进行焊前焊后热处理的条件下,分别采用低强匹配自动焊和高强匹配常规手工焊方法进行焊接试验。通过对焊接接头的力学性能和金相组织分析比较,证明该钢具有良好的焊接适应性。Two kinds of welding methods：strength low-matched with automatic welding and strength over-matched with manual welding, were applied to the ultra-fine micro-alloy steel without pre- ＆ post- heating treatment. The tested results show that the steel has good welding adaptability through analyzing the mechanical properties and metallurgical structures of the welded joints.
