The microstructure characteristics in weld metal and heat affected zone（HAZ） are described, and the toughening mechanism of weld metal is discussed from four aspects of cleanliness, alloying, refining and homogenizing. The development of special low phase transformation spot welding materials and the development of post welding treatment methods are also introduced. Finally, the development trend of welding materials for marine engineering is pointed out. 海洋工程用焊接材料 韧性 针状铁素体 夹杂物 welding consumables for marine engineering toughness acicular ferrite inclusion TG42 国家自然科学基金(51774213) 2022-03-08 9 50
