본 발명은 시편거치대에 관한 것으로서, 특히 고강도 철강소재의 점용접 시험시편의 시편거치대에 관한 것이다.The present invention relates to a specimen holder, and more particularly, to a specimen holder of a spot welding test specimen of high strength steel material.

일반적으로, 차체부품로써 요구되는 철강소재는 부위별로 상당히 다양하며 경량화를 달성하기 위한 강도값 향상과 복잡한 형상의 제조가 필요한 부분에 대한 가공성 확보가 우수해야 하고 또한 월등한 용접특성을 갖춰야만 점차 강화되는 국제적 충돌시험규제를 만족시킬 수 있다. In general, the steel materials required for body parts vary considerably from site to site, and should be excellent in securing the workability for parts requiring improvement in strength value and manufacturing of complex shapes to achieve light weight, and should be strengthened gradually with superior welding characteristics. Meet international conflict test regulations.

고강도 철강소재의 강도향상 측면에서 1980년도를 전후해서는 고용강화강 및 석출강화강의 개발을 통해 50kgf/㎟급의 인장강도를 달성하였으며 1980년도 이후로는 DP(Dual phase)강 및 TRIP(Transformation Induced Plasticity), TWIP(Twin Induced Plasticity)강의 개발을 통해 80kgf/㎟급 이상의 인장강도를 구현하고 있으며 지속적으로 인장강도값을 향상시키기 위해 노력하고 있다. In terms of the strength improvement of high strength steel materials, around 1980, it achieved 50kgf / mm2 tensile strength through the development of solid steel and precipitation hardened steel. Since 1980, DP (Dual phase) and TRIP (Transformation Induced Plasticity) have been achieved. ), Through the development of TWIP (Twin Induced Plasticity) steel, the tensile strength of more than 80kgf / ㎜ class is being implemented, and strives to continuously improve the tensile strength value.

그러나 소재강도 향상에 기여하기 위해 첨가원소의 다량첨가로 인하여 강판소재 표면에 Mn 및 Si 원소 등이 농화되어 이들은 결국 도금층의 밀착성을 저하시키고 낮은 용접특성이 나타나는 것이 문제되고 있다. However, Mn and Si elements are concentrated on the surface of the steel sheet due to the addition of a large amount of additive elements in order to contribute to improving the strength of the material, which leads to a problem that the adhesion of the plating layer is lowered and low welding properties are exhibited.

이에 고강도 소재개발에 맞춰, 정확하고 신뢰성있는 점용접 평가기술이 확보되어야만 최적의 용접조건을 도출 할 수 있게된다.Therefore, in accordance with the development of high strength materials, accurate and reliable spot welding evaluation technology must be secured to derive optimal welding conditions.

그러나, 상기와 같은 용접시편시험에서는 점용접 작업방법상의 기본적인 요구사항과 용접부 품질평가 방법이 규정되어 있음에도 불구하고 통전전류가 흘러 용접이 시작되기 직전단계(시편겹침, 겹침시편이 상,하 용접전극 사이에 위치되는 과정)까지는 오로지 작업자의 수작업에 의해 이뤄지므로, 감전에 의한 안전사고 및 겹침부 정중앙부 오조준으로 용접부 특성평가시 측정값의 재현성과 반복성이 크게 저하되는 문제점이 있다.However, in the welding specimen test as described above, despite the basic requirements of the spot welding method and the welding part quality evaluation method, the stage immediately before the welding current flows through the welding (overlapping and overlapping specimens, the upper and lower welding electrodes) Since the process is located only between the manual labor of the operator, there is a problem that the reproducibility and repeatability of the measured value are greatly degraded during the evaluation of the weld characteristics due to safety accidents due to electric shock and misalignment of the central part of the overlapping part.

본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 창출된 것으로서, 용접시편 겹침부에 용접전극이 정조준될 수 있는 시편거치대를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, and an object of the present invention is to provide a specimen holder on which a welding electrode can be aimed at the overlapping weld specimen.
