Dynamic analysis of globular metal transfer in gas metal arc welding
Brief Summary:
- A mathematical model to describe the globular transfer in gas metal arc welding is developed.
- This work is both theoretical and experimental.
- Using the volume-of-fluid (VOF) method, the fluid-flow and heat-transfer phenomena.
- During the impingement of a droplet on a solid substrate, arc striking.
- The impingement of multiple droplets on the molten pool and finally the solidification after the arc extinguishes are dynamically studied.
- A He-Ne laser in conjunction with the shadow-graphing technique is used to observe the metal-transfer processes.
