Abstract A software system for computing the size and shape of bead-on-plate submerged arc (SA) welds is described in this presentation. The system is based on algorithms originated by McGlone et al., Chandel et al. and Yang et al. Essentially the system consists of a specially designed interface for welding/materials/design/fabrication engineers, automated plotting for parametric studies, a simplified data base for storing/editing/retrieving frequently used welding parameters and pictorial graphics for displaying weld size and shape. The use of the system in engineering practice is discussed at some length.
