Description
Arc welding is widely used in various industries due to its versatility and efficiency in creating strong, durable bonds between metal components. This research paper investigates the arc interaction in Tungsten Inert Gas/Metal Inert Gas (TIG/MIG) hybrid welding through numerical simulation. The study aims to understand the effects of arc behavior on the welding process and explore the potential benefits of hybrid welding techniques. By analyzing the interaction between TIG and MIG arcs, this research seeks to enhance the efficiency and quality of welding processes. The research employs computational fluid dynamics (CFD) to develop a numerical model of the TIG/MIG hybrid welding process. The model incorporates mass conservation, momentum conservation, energy conservation, current conservation, and Maxwell-Ampère equations to simulate the arc interaction. Parameters such as torch angles, welding current, and shielding gas composition are varied to analyze their impact on arc behavior. The numerical simulation reveals that the interaction between TIG and MIG arcs significantly influences the temperature distribution and arc plasma characteristics. Increasing the torch angle leads to higher arc plasma temperature and improved electrical conductivity between the electrodes, resulting in a more stable arc and enhanced weld quality, increasing the welding bond strength by 8% compared to MIG welding alone. The study demonstrates the importance of understanding the interaction between TIG and MIG arcs in hybrid welding processes. By leveraging numerical simulation techniques, researchers can gain valuable insights into arc behavior and its impact on welding outcomes. The findings of this research contribute to the advancement of TIG/MIG hybrid welding technology and provide a foundation for further exploration in the field of arc welding additive manufacturing.
