摘要
对国内应用较少、耐蚀性强的SAF2507超级双相钢的特点进行分析,对比Q345R与SAF2507焊接性,参考异种钢焊接,利用舍弗勒图选取合适焊材。针对Q345R与SAF2507超级双相钢焊接进行试验分析并归纳其焊接工艺,提出了防止缺陷产生的焊接方法和保证焊接质量的措施。
In this article, the features of deluxe stainless steel SAF2507, which is seldom used in China and is well anticorrosive, were analyzed. With the comparison of the weldabilities of Q345R and SAF2507 and the reference for welding of heterogeneous steels, the appropriate welding consumers were selected by using Schaeffler diagram. Welding tests for Q345R and SAF2507 were carried out. After the analysis and summarization of their welding procedures, the welding method which can protect the occurrence of welding defects and measures for controlling quality were proposed.
