The influence of weld heat input on weld joint between B610CF and 16MnR steel using shielded metal arc welding method was investigated by metallographic experiment and mechanical properties experiment. Metallographic experimental results show that in welded metal with the increasing of weld heat input the quantity of bainite is decreased and crystalline grain is larger; but in both B610CF and 16MnR steel heat affected zone, with the increasing of weld heat input there is no distinct difference in microstructure. Mechanical property experimental results show that in weld metal with the increasing of weld heat input the impact toughness decreases, but in both B610CF and 16MnR heat affected zone, there is less difference in impact toughness; and there is no distinct difference in tensile strength and plasticity of weld joint, which is consistent with the metallographic experiment results.
