DI Xinjie, BA Lingzhi, LI Chengning. Research status and development trend of welding consumables for offshore engineering[J]. Eletric Welding Machine2020, 50(9): 92-102.DOI: 10.7512/j.issn.1001-2303.2020.09.10.
The research progress and market status of welding consumables for marine engineering at home and abroad were reviewed. 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.
