As a kind of main non-metallic inclusions of ER50-G for welding wire,TiN has an obvious influence on the property of ER50-G.The sample with a Ti content of 0.16% obtained from the production process of ER50-G is examined by FE-SEM.Based on the chemical composition of the wire rod,the critical temperature for precipitation of TiN is calculated to be 1 822.6 K,which is above the liquidus of ER50-G.TiN precipitates in both liquid and solid phases,but mainly in liquid phase.It can be concluded that in the production of ER50-G,the precipitation amount of TiN particle in liquid steel is higher than theoretical value while lower in solid phase.Finally a practical curve of TiN precipitation is obtained.
