    • A fixture is provided for testing the shear strength of a longitudinal weld which interconnects a plurality of planar blanks forming a tailor welded blank. The fixture includes a first pair of triangular shaped face plates connected to one side of the tailor welded blank and a second pair of triangular shaped face plates connected to the other side of the tailor welded blank. Each of the face plates includes a transverse edge which extends across the longitudinal weld connecting the planar blanks. The fixture further includes each of the transverse edges having a first portion and a second portion spaced from and parallel to the first portion. The fixture also includes an isolation portion interconnecting the first and second portions of the transverse edges adjacent the longitudinal weld for isolating a portion of the weld whereby the isolated portion of the weld is tested for shear resistance by applying a tensile load to the first and second pair of face plates.
    • 提供了一种固定装置,用于测试纵向焊缝的剪切强度,该纵向焊缝互连多个形成裁缝焊接坯料的平面坯料。 夹具包括连接到裁缝焊接坯料的一侧的第一对三角形面板和连接到定制焊接坯料另一侧的第二对三角形面板。 每个面板包括横跨连接平面坯料的纵向焊缝延伸的横向边缘。 固定装置还包括每个横向边缘具有与第一部分间隔开并平行于第一部分的第一部分和第二部分。 固定装置还包括隔离部分,其将横向边缘的第一和第二部分相互连接在纵向焊缝上,用于隔离焊接的一部分,由此通过将拉伸载荷施加到第一和第二部分来测试焊接的隔离部分的抗剪切性 一对面板。
