| 主要梳理和综述了超级双相不锈钢2507焊接方面的研究工作，从而对超级双相不锈钢2507焊接工艺进行指导。从超级双相不锈钢2507焊接工艺、焊接接头两相比例调节两个维度进行综述，其中，超级双相不锈钢2507焊接工艺部分从钨极氩弧焊、埋弧焊、等离子弧焊、激光焊、电子束焊、激光-电弧复合焊这6种焊接工艺开展评述，焊接接头两相比例调节部分从调整焊接热输入、焊后热处理、添加合金元素镍或氮3个方面进行评述。结合国内外研究现状，探讨了超级双相不锈钢焊接如何控制接头两相比例这一关键问题。研究现状表明:钨极氩弧焊、等离子弧焊和激光焊可以较好地实现超级双相不锈钢优质焊接;添加合金元素镍或氮是调控焊接接头两相比例的重要手段。开展超级双相不锈钢2507焊接工艺研究现状的综述具有重要意义，向熔池过渡合金元素的高能量密度焊接工艺可能是超级双相不锈钢焊接的优选技术。 |
| 英文摘要: |
| The research work on welding of super duplex stainless steel 2507 was summarized, so as to guide the welding process of super duplex stainless steel 2507. The welding process of super duplex stainless steel 2507 and the two-phase proportion adjustment of welded joint were reviewed. The welding process of super duplex stainless steel 2507 was reviewed from six welding processes including argon tungsten arc welding, submerged arc welding, plasma arc welding, laser welding, electron beam welding and laser-arc composite welding. The two-phase proportion regulation of welded joint was reviewed from three aspects:adjusting welding heat input, post-welding heat treatment, adding alloying elements nickel or nitrogen. Combining with the research status at home and abroad, the key problem of how to control the two-phase ratio of super duplex stainless steel joints was discussed. The research status shows that argon tungsten arc welding, plasma arc welding and laser welding can achieve excellent welding quality of super duplex stainless steel; adding alloying elements nickel or nitrogen is an important means to regulate the two-phase ratio of welded joints. It is of great significance to review the research status of the welding process of super duplex stainless steel 2507. The high energy density welding process of the transition alloying elements to the molten pool may be the optimal welding technology of super duplex stainless steel. |
