Abstract Scope |
While known to affect metal quality, yield, and process efficiency, the metal vapor plasma arc behavior in vacuum arc remelting has remained elusive to reliable measurements and controls. Due to the unpredictable nature of the arc, complete process automation and quality control has been limited in its success to prevent defects. However, the application of magnetic sensors in the early 2000s illuminated the behavior of the arc through analysis of the measurements with predictive models. Since then, we have pushed the technology to not only measure the position and distribution of the arc at the gap, but also to measure the vertical position of the arc gap, side-arcs, the concentricity of the electrode, and to provide feedback for active magnetic control, in order to optimize metal quality and yield. |
