| Abstract: | Aiming at some easily arising problems in pipeline steel Charpy impact test,combined with characteristics of oscillographic impact test,a conclusion was made that it can reflect the situation of material＇s toughness more truthful when using the oscillographic impact to analyze toughness of weld and base material of SAWH pipe than that obtained by the common impact testing machine.And the necessity of using the oscillographic impact in the pipeline steel＇s toughness test was pointed out. |
