Methods to Improve TIG Welding Efficiency

With its excellent welding quality and high arc stability, tungsten inert gas (TIG) welding occupies a significant proportion in industrial production. However, the low current-carrying capacity of tungsten electrodes results in low welding efficiency, which significantly hampers the industry's development. By compressing the arc and increasing the deposition efficiency, the efficiency of TIG welding can be improved. This study has reviewed three optimization methods, including optimizing process conditions, improving equipment, and external constraints. It has also analyzed the principles and research status of these methods. Further, a magnetic tungsten electrode and a double-torch TIG welding method have been prospected. The former can enhance the magnetic field effect of magnetic control TIG and reduce the volume of welding torch. The latter can increase the parameter adjustability of double tungsten electrode welding. The development of high-efficiency TIG welding promotes the progress of industry and the development of human civilization.
