主要综述了国内外铁素体不锈钢焊接的研究和发展现状，焊接热过程会导致铁素体不锈钢接头焊缝和HAZ晶粒严重长大，从而造成接头塑韧性和耐蚀性能下降。激光焊、复合热源焊接、脉冲电弧焊、搅拌摩擦焊等新型焊接方法被用来焊接铁素体不锈钢以获得性能更好的接头。并且可以通过控制热输入、提高冷却速度、添加稳定元素、电磁搅拌或超声振动来细化晶粒，提高接头性能。进年来，模拟计算也被用到铁素体不锈钢焊接的研究当中。
主要綜述瞭國內外鐵素體不鏽鋼銲接的研究和髮展現狀，銲接熱過程會導緻鐵素體不鏽鋼接頭銲縫和HAZ晶粒嚴重長大，從而造成接頭塑韌性和耐蝕性能下降。激光銲、複閤熱源銲接、脈遲電弧銲、攪拌摩抆銲等新型銲接方法被用來銲接鐵素體不鏽鋼以穫得性能更好的接頭。併且可以通過控製熱輸入、提高冷卻速度、添加穩定元素、電磁攪拌或超聲振動來細化晶粒，提高接頭性能。進年來，模擬計算也被用到鐵素體不鏽鋼銲接的研究噹中。

The situation and development of welding of ferrite stainless steel is discussed in detail, generally speaking, the ferrite stainless steels are always subjected to excessive grain growth in the fusion zone and heat affected zone, which would cause a deleterious effect on the mechanical and corrosion resistance properties of the steels. Laser beam welding, hybrid welding, pulsed arc welding and friction stir welding are used to obtain joints with better properties. And control of heat input, raising cooling rate, adding stabilization elements, magnetic arc oscillations and ultrasonic vibration are used to get fine grain. In recent year, simulation and calculation are also used to study the welding of ferrite stainless steels.
