    LJG315 roadheader driven sprocket is welded by 35CrMo and 27SiMn steel. With mixed gas protection and 220℃preheated, 35CrMo steel and 27SiMn steel were welded. The microstructure of welded joints was observed and the hardness was tested. The production showed that the welded joints can meet the requirements of mechanical properties of driven sprocket.
