The deposited metal of flux cored submerged welding wire W110 used for rollers building up was investigated by welding thermal simulation.By means of welding thermal simulation experiment,hardness testing,and micro-analysis,the sffuctttre and properties of the deposited metal were analyzed at different welding thermal cycles.The results show that the Ms point of W110-deposited metal is 260~280℃,the preheating temperature of W110-wire is 280~300℃ and the intedayer temperature should be higher than 260℃ during welding,and temperature should be not at 450~550℃.
