Testing and Analysis of High-Speed Camera for Pulse MIG/MAG Welding Droplet Transition

Abstract:

The droplet transition of electrical arc welding is a complicated process that combines heat, mass and momentum transfer. A high-speed camera system with laser in the background is established to observe the fast changing process of droplet transition. A group of high-speed camera pictures which indicate that the size and shape of droplet have strong uncertainty are taken and analyzed. The results show that the randomness of droplet size and shape are decided by its internal and external random factors, such as: the changing of the length of welding wire stretched out, the fluctuation of the feed speed of welding wire etc.
