摘要:
使用优化的焊接工艺参数,对ASTM A928 S31803双相不锈钢进行焊接,获得了性能良好的焊接接头。在给定工艺参数下,焊缝及热影响区生成奥氏体-铁素体双相组织,焊接接头无脆化区生成,耐点蚀性能和电化学腐蚀性能满足要求。在研究了双相不锈钢焊接性能特点的基础上,完成了该接头的腐蚀性能评定试验,可为焊接从业者提供参考。
Abstract:
In this paper, the ASTM A928 S31803 duplex stainless steel was welded using the optimized welding parameters, and the welded joints with good performance were obtained. Under the given process parameters, the austenite-ferrite structure is generated in weld and HAZ, no brittle region is generated around the welding joint, and the pitting corrosion resistance and electrochemical corrosion properties meet the requirements. On the basis of duplex phase stainless steel welding performance characteristics, the corrosion performance verification test of the joint was completed, which provides reference for welding practitioner.
