Failure Analysis on the Connecting Rod of Framed Saws

LU Wen-dong

Abstract

The fracture of the frame saw's connecting rod tested in macroexamination,chemical component analysis,metallographic examination and microhardness.The test results indicated that early failure of the connecting rod was fatigue fracture,and the failure were caused by low carbon content of material which was treated with improper heat treatment and incomplete penetration welds.
