Friction stir welding assisted by micro-plasma arc (P-FSW) is a solid-state welding method. It uses a micro-plasma arc to preheat materials, which improves their flow and reduces welding defects. This technique effectively joins both similar and dissimilar materials, enhancing mechanical properties and controlling temperature distribution during the process. A comparative study reveals significant improvements in … Read more

Arc welding uses heat to melt filler material, creating a welded joint. It is a fusion process that joins two parts together. In contrast, friction welding generates heat by moving one part quickly against a stationary part. This method forms a strong joint through mechanical joining without melting the materials. Arc welding, on the other … Read more

Fuerschbach is a dimensionless parameter used in arc welding. It estimates weld size, power, and speed. This model considers thermal properties of materials. Fuerschbach applies to techniques like Gas Tungsten Arc Welding (GTAW) and Plasma Arc Welding (PAW). It helps optimize melting efficiency and reduce the heat-affected zone. Understanding Fuerschbach’s Dimensionless Parameter provides insights into … Read more
