GB/T 25774.2-2016 specifies the preparation and testing methods for tensile and impact test specimens of welded joints in steel welding consumables under single-run and two-run welding conditions. It applies to arc welding consumables for determining joint strength and toughness, excluding electroslag and gas-electric vertical welding. Key requirements include base metal specifications, test piece preparation (e.g., reverse deformation to prevent angular distortion), and welding conditions (flat position, preheat and interpass temperature control). The standard modifies ISO 15792-2:2000 with editorial adjustments, such as replacing international references with equivalent Chinese standards.
GB/T 25774.2-2016规定了钢的焊接材料在单面单道焊和双面单道焊条件下焊接接头拉伸和冲击试样的制备及检验方法。标准适用于电弧焊焊接材料，用于测定接头强度和韧性，但不包括电渣焊和气电立焊。主要内容包括试验用母材要求、试件制备（如反变形防止角变形）、焊接条件（平焊位、预热和道间温度控制）等。该标准修改采用ISO 15792-2:2000，并做了编辑性调整，如删除国际引用文件并替换为国内标准。
