전투차량용 방탄강 용접재료 국산화를 통한 품질향상 Improvement of Quality of Bulletproof Steel Welding Wires for Combat Vehicles Through Localization
pp.774-779
This study is to investigate the improvement of quality and cost reduction of welding materials for combat vehicles through localization. The existing imported welding wires and localized welding wires were evaluated. The evaluation of the welding wires was performed for the feedability, chemical/mechanical properties, macro testing, and weldability. As a result of evaluation, the localized welding material met all the evaluation standard values. In addition, it showed excellent performance in terms of weldability and feedability. It is judged that the welding quality is improved thanks to the improvement of feeding characteristics through the localization of the welding material, and the fatigue of the worker is also expected to be relieved.
