Arc Welding Processes as Practical Solutions to Join Ceramics: Progress and Future Outlook

Arc welding of ceramic materials remains a significantly underdeveloped research topic in materials science and manufacturing. This is primarily due to the difficulty in managing thermal gradients and stress concentrations during arc welding, which often result in cracking and poor joint reliability in ceramic components. However, recent advances suggest that gas tungsten arc welding and plasma arc welding could offer a promising pathway for ceramic joining if thoroughly investigated. While these techniques have proven effective in the precision welding of metals, their application to ceramics is met with several challenges, driven by the material's inherent brittleness and high melting points. Consequently, further research is essential to understand the arc welding processes on ceramic materials and develop solutions to optimize and establish reliable welding procedures. Therefore, expanding this topic could have a significant impact on key engineering applications, where ceramic materials are increasingly in demand.
