GB/T 25774.2-2016 Test methods for welding consumables - Part 2: Preparation of single-run and two-run technique test specimens in steel 1 Scope This part of GB/T 25774 specifies the preparation and inspection methods of tensile specimens and impact specimens for single-run welding and double-run welding joints of steel welding consumables. This part is applicable to the determination of joint strength and toughness of arc welding consumables of steel under single-run welding and double-run welding conditions. This part is not applicable to electroslag welding and gas-electric vertical welding. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 2650 Impact test methods on welded joints (GB/T 2650-2008, ISO 9016: 2001, IDT) GB/T 2651 Tensile test method on welded joints (GB/T 2651-2008, ISO 4136: 2001, IDT) GB/T 18591 Welding - Guidance on the measurement of preheating temperature, interpass temperature and preheat maintenance temperature (GB/T 18591-2001. Idt ISO 13916: 1996) 3 General Principles The welding consumables to be tested are representative products that the manufacturer needs to classify or inspect. Tensile and impact specimens of welded joints are prepared according to the following requirements. 4 Test base materials The base materials used for the test shall meet the requirements of the corresponding welding consumables product standard. 5 Preparation of specimens The test plates shall be reversed deformed or restrained before welding to prevent angular deformation, and the specimens are not allowed to be corrected after welding. As for single-run welding, a backing plate may be added on the back. Arc starting plate and arc closing plate can be used for welding, see Table1.
