Abstract

To improve productivity and improve the welding process, we have studied the automated system of the weld by applying a tandem welding. Then, the speed of the welding process is improved, production of industries is increasing. Productivity of the industrial sector has increased the application of tandem welding for automated system of welding. But quality assurance for the product take place welding defects in the welding process because the speed of the process is increased. Definitive research solutions an dit's actuality, however, there is insufficient. Accordingly, it is a situation that the performance of the weld to ensure quality of the weld is required urgently after the welding process. Comparing and analyzing the results of passing each experiment of the two-electrode welding and the welding electrode1, a study attempted to quality assurance of the welded joint portion.

산업의 생산성 향상 및 용접공정의 개선을 위해 용접공정에 탠덤 용접의 적용가능성을 확인하고자 실험을 통한 용접이음부위의 성능평가를 실시하였다. 1전극 용접과 탠덤 용접의 실험을 통해, 비드의 형상을 비교 분석하고, 용접실험의 결과시험편에 대하여 3가지 시험(인장시험, 경도시험, 굽힘시험)을 실시하였다. 또한 결과시험편에 대한 기계적 성질을 분석하여 탠덤 용접이음부위에 대한 성능평가를 수행 하였다. 본 연구는 탐뎀 용접이음부위에 대한 기계적 성질 및 안전강도 보증을 목적으로 하고 있으며, 인장시험, 굽힘시험 및 경도시험을 통해 탠덤 GMAW 의 신뢰성과 효율성을 확인하고자 한다.
