摘要
兼具钛合金和钢优点的钛/钢复合板,被广泛应用于海洋、船舶、机械化工等工业领域中,而焊接技术在其推广应用的过程中发挥了不可替代的关键作用。讨论了钛/钢复合板焊接的特点,重点从坡口形式和过渡层的设计、选择与添加两方面综述了钛/钢复合板的钨极氩弧焊、熔化极气体保护焊及激光焊等焊接方法的研究现状,分析了不同工艺下接头的微观组织、力学性能等特征。结果表明,通过合理的坡口设计和过渡层的添加,可以实现钛/钢复合板的良好焊接。然而,当前钛/钢层状复合板焊接还存在工艺复杂、效率低等主要问题,有待进一步解决。同时,还对钛/钢复合板焊接技术未来发展的方向进行了展望。
Ti/steel composite plates,which both have the advantages of titanium alloy and steel,are widely used in the fields of oceanographic,marine,mechanical and chemical industries,while welding technology plays an irreplaceable key role in its popularization and application.This paper discusses the welding characteristics of Ti/steel composite plates.The research status of TIG welding,gas metal arc welding and laser welding of Ti/steel composite plates are summarized from the aspects of groove form,design,selection and addition of transition layer.The microstructure and mechanical properties of joints under different technologies are analyzed.The results show that the welding of Ti/steel composite plates can be realized by reasonable groove design and adding transition layer.However,there are still some problems in the welding of Ti/steel composite plates,such as complex process and low efficiency.At the same time,the future development direction of welding technology for Ti/steel composite plates is prospected.
