摘要：
Using semi automatic manual flux cored welding methods, selection of Phi 2.8 (V-100Mo) cored wire for overlaying welding in 36 (Q235B) steel substrate with different welding processes for multi-layer welding experiment. The deposited metal microstructure and mechanical properties of welding rod are analyzed. The hardness and bending strength of deposited metal are investigated. The results show that the hardness of the deposited layers depends on the microstructure. After welding, bending strength improved significantly by using heat preservation and slow cold. Finally the reasonable welding process which has high hardness and good bending performance is determined.
