摘要
Abstract
A SA508-3-1 material product failed the Drop-Weight test NDT results many times during the mechanical test.The Drop-Weight test is a one-time test and retesting is not allowed.In order to find out the factors that affect the Drop-Weight test NDT results and accurately determine the NDT temperature of the material,a detailed analysis was conducted on the effects of the Drop-Weight test weld length,weld notch width,weld notch bottom height,sample type,and welding heat affected zone.The research results show that appropriately shortening the Drop-Weight test weld length or reducing the weld notch width has a positive effect on reducing the NDT temperature of the Drop-Weight test;the weld notch bottom height and the Drop-Weight test specimen thickness have no obvious effect on the Drop-Weight test NDT temperature;the depth of the Drop-Weight test specimen's welding heat affected zone is positively correlated with the Drop-Weight test NDT temperature.关键词
