摘要
Abstract
The poor resistance spot weldability of martensitic stainless steel hinders its application in thin plate structure.The physical and mechanical properties of martensitic and austenitic stainless steel are compared,and the root cause of poor resistance spot weldability of martensitic stainless steel was analyzed.The research status of resistance spot welding of martensitic stainless steel was reviewed,including the microstructure formation mechanism,mechanical properties and fracture mode of spot welding joints.Moreover,some technological methods for improving spot weldability and increasing bearing capacity of martensitic stainless steel joints have been paid special attention,such as introducing secondary pulse current to improve the nugget toughness,introducing interlayer to change the nugget microstructure and applying hybrid welding technology.Finally,the application prospects of these technical measures are also prospected.关键词
