Welding is a common connection technology in the use of metal structural parts.Affected by various factors,the structural parts are prone to welding failure problems,which can reduce their service life.Firstly,the conditions of welding failure of metal structural parts are analyzed,and then the causes of welding failure are introduced in detail from three aspects of plastic fracture,brittle fracture and fatigue fracture.Finally,targeted preventive measures are put forward for three common failure forms.It is of certain significance to improve the welding quality of metal structural parts and to reduce the welding failure probability
