Analysis of Metal Transfer and Usability of High Cellulose Electrode

By using high-speed photographic method and usability experiments, the metal transfer form and usability of high cellulose electrode have been analyzed.The results show that the metal transfer forms of high cellulose electrode contain spray transfer,explosive transfer and short circuiting transfer.The spatter forms include big and small droplet spatters.The transfer and spatter of big droplets show obviously periodic characteristic, and the small droplet spray transfer and spatter exist through whole welding.Strong and regular spray transfer form is advantageous to the usability.The big droplet spatter is the main reason for bad usability, e.g.low deposition efficiency, unstable arc etc,.and it should be analyzed and prevented further.
