Abstract
In welding processes of high-strength steels, it was difficult to match the strength and toughness between weld metal and base metal. Thus it was urgent to refine regulation and control systems for alloying elements and improve strengthening and toughening mechanism of high-strength steel weld metals. Bainite is the important microstructure and had a significant influence on the toughness of high-strength steel weld metals, so formation mechanism of typical bainite and bainite analysis methods were summarized. The influences of alloying elements on the microstructure and mechanical property of high-strength steel weld metals were reviewed. Values of each alloy element were recommended, which aimed to give reference for regulation and control systems for alloying elements of high-strength steel weld metals.
