本研究中，采用线切割沿焊接试板焊缝方向，拉伸试样按照GB/T 2652-2008的有关要求，在焊缝正中切取直径为5mm，标距为60mm的比例拉伸试样，按照国标GB/T 228.2-2015的标准进行室温拉伸试验，测得钢板的室温屈服强度值、抗拉强度值、断后伸长率、断面收缩率等。

In this study, wire cutting was used along the weld direction of the test plate. According to the relevant requirements of GB/T 2652-2008, a proportional tensile sample with a diameter of 5mm and a standard distance of 60mm was cut from the middle of the weld, and tensile test was conducted at room temperature according to the national standard GB/T 228.2-2015. The yield strength, tensile strength, elongation after fracture and area reduction of steel plate at room temperature were measured.
