고생산 전자빔 용접용 Rotary시스템 기술개발 및 사업화 방안

Abstract

In the welding industry, minimizing the vacuum evacuation process is important because this process occupies approximate 70% of the total welding time. One available solution is to provide a rotary system that can perform simultaneous installation for multiple welding targets in a chamber. The present work aims at developing such rotary system for electron beam welding. The developed system can maintain the balance of the welds in a vacuum chamber of the electron beam through simultaneous welding along with accommodating various material sizes and performing continuous and multiple welding. It also enables synchronized control to adjust multiple dimensional movements for both plane welding and curved surface welding. Furthermore, it involves the multi-clamp function that allows to secure the uniformity of welding and to minimize strain of the welding material through controlling the rotational speed on curved surfaces and the linear speed on plane surfaces. For such purpose, this report includes: the analysis of external environment and internal capability related to the developed system, the design and implementation of the system, the specification of the relevant business model and expected effect, and the identification of a technology roadmap for further research and development with consideration of commercialization.
