奥氏体型不锈钢与低合金钢在化学成分和物理性能方面有很大的差异,特别是中厚板异种钢的焊接拘束力大、冷裂倾向大,为了获得一个满意的焊接接头,必须对两种钢的化学成分、力学性能、物理性能、组织和形成的焊接接头可能出现的问题进行对比分析,来确定合理的焊接工艺。 Austenitic stainless steel and low alloy steel in the chemical composition and physical properties are very different, especially the plate dissimilar steel welding binding force, cold cracking tendency, in order to obtain a satisfactory welded joints, we must Two kinds of steel chemical composition, mechanical properties, physical properties, the formation of welded joints and the problems that may arise comparative analysis to determine the reasonable welding process.
