摘要：The image signal of intermittent high energy pulsed droplet transfer are acquired using high-speed camera systems and self-developed high-energy pulsed cold patch machine. Then, the droplet transfer characteristics in high-energy pulsed cold patch process were discussed. The results showed that in the high-energy pulsed cold patch repair process, welding wire and substrate surface were melted by instantaneous high voltage arc and dropwise droplet were formed. And the droplet jitter, roll by gravity and surface tension and then cooled and solidified rapidly, metallurgical fused at the end. © (2014) Trans Tech Publications, Switzerland.
