JIG FOR A TENSILE TEST OF A SPOT WELDING SAMPLE, CAPABLE OF ACCURATELY AND FIRMLY FIXING A SPOT WELDING SAMPLE

摘要

PURPOSE: A jig for a tensile test of a spot welding sample is provided to improve a shape of a jig in order to correspond to a spot welding sample, thereby accurately and firmly fixing the spot welding sample.;CONSTITUTION: A jig for a tensile test of a spot welding sample comprises an upper jig(310), an upper supporting member(320), a lower jig(330), and a lower supporting member(340). The upper jig is formed on the top of the spot welding sample of a cross shape, thereby fixing the spot welding sample. The upper supporting member is extended from a top surface of the upper jig and coupled to an upper grip of a tensile testing device, thereby supporting the upper jig. The lower jig is formed in the bottom of the spot welding sample, thereby fixing the spot welding sample. The lower supporting member is extended from the bottom surface of the lower jig and coupled to a lower grip of the tensile testing device, thereby supporting the lower jig.;COPYRIGHT KIPO 2013
