Research and Development of High Energy Pulse Precision Cold–Welding Technology
High energy pulse precision cold–welding technology is a new welding technology that using high-energy pulsed, which arc produced between tungsten electrode and the workpiece, to melt the base metal and welding wires quickly. The quality and accuracy of this technology are equal to laser welding. It can repair the surface of parts, pitting, cracks and other defects of special-shaped surface. This article discusses research process of the High energy pulse precision cold–welding technology and its working principle, performance characteristics and equipments. It also presents the technology of cold welding materials and processes to explore the High energy pulse precision cold–welding technology’s potential application and future development in the field of surface engineering.
