TLDR
In this article, the authors developed a high quality cable lug joint using electromagnetic force and compared it with various cable lug joints by comparing the electrical contact temperature of the developed cable-lug joint with those of the manufactured ones.Abstract:
Recently, there has been a trend in the manufacturing process to focus on the durability of cable lug joint, especially in welding process due to the poor cable lug joint causes many troubles on products and workers during manufacturing process. Therefore development of high quality cable lug joint is important for successful manufacturing process and safety of worker. The Magnetic Pulse Forming(MPF) is one of efficient way to developed a high quality cable lug joint. In MPF, a high strain rate forming process, utilizes a high velocity oblique collision on the workpiece to be formed in required shape. The objective of this paper is to develop of high quality cable lug joint using electromagnetic force. To successfully accomplish this goal, section and electrical contact temperature of developed cable lug joint has been compared with various cable lug joint. Electrical contact temperature of developed cable lug joint by electromagnetic force is lower than manufactured cable lug joint by pressurer and hydraulic pressurer.read more

Review of warm forming of aluminum-magnesium alloys
TL;DR: In this paper, the formability and surface quality of the final product of these alloys are not good if processing is performed at room temperature, however, they have been shown to increase at temperature range from 200 to 300°C and better surface quality has been achieved.
