| Abstract: | t In order to collect welding arc images and to observe droplet transfer process, by using the key technologies of high-speed image pickup, such as back light technology, optical magnification and the selection of high-speed vedio parameters, a valuable high-speed video system with laser as back light is established. Online observation and monitoring of welding process are real- ized with the system. The results of this work can effectively help the further study of high-speed technology for the phenomenon of arc welding and droplet transfer in MIG wielding process. |
