Principle and Application of Magnetic Pulse Welding

Journal of the Korean Welding and Joining Society, 2008
최근 금속가공산업은 자동차, 조선 기계, 전자 등의 부품소재 제조에 있어 핵심적인 산업으로 자리하고 있다. 특히 가장 많은 비중을 차지하고 있는 용접산업은 저임금을 바탕으로 한 중국기술의 추격과 선진국의 고품질화에 직면하고 있으며 이러한 문제를 해결하기 위하여 친환경 공정기술의 개발과 신기술을 통한 제품의 부가가치 제고가 요구된다. MPW는 자기장에 의한 전자기력을 사용하므로 물리적인 접촉 없이 금속을 가공하는 방법으로서, 용접(brazing과 soldering 포함), 금형 및 소성가공공정에서 환경오염 발생원인 용접재료, 가스, 용가재, 플럭스, 윤활유 및 세척유 등이 필요 없이도 고품질의 제품을 생산할 수 있는 친환경적인 ...

Workpiece positioning during magnetic pulse welding of aluminum-steel joints

, 2022
S.101-109Magnetic pulse welding (MPW) enables the fabrication of joints via the harnessing of Lorentz forces, which result from discharging a current pulse through a coil. In the process, an outer piece (flyer) is accelerated onto an inner piece (parent),

Mechanical properties and joining mechanisms of magnetic pulse welding joints of additively manufactured 316L and conventional AA5052 aluminum alloy

Journal of Materials Research and Technology, 2023
Magnetic Pulse Welding (MPW) is a new solid-phase welding (no heat input and no auxiliaries) technique. This results in joints with almost no brittle intermetallic compounds (IMC) and hence provides excellent joint quality. In this study, 316L fabricated
