Stress analysis on welded seam and carbide bit of the pick-shaped cutter

LIU Chun-sheng (Dept. of Mechanical Engineering, Heilongjiang Scientific and Technical Institute,Haerbin 150027,China)  
According to concrete structure of the sheerer pick—shaped cutter and carbide bit, this paper analyses the two typical scatter forms of welded seam stress in detail. And it provides stress抯 varying law and theory calculation expression of stress. The result of the stress scatter condition are identical with practice by using finite element analyses software .All this provides the theory method and channel to improve cutter抯 working reliability through changing cutter抯 structure parameter and installment parameter and welded seam structure.
