GMAW welding optimization using genetic algorithms [PDF]
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2004 This article explores the possibility of using Genetic Algorithms (GAs) as a method to decide near-optimal settings of a GMAW welding process. The problem was to choose the near-best values of three control variables (welding voltage, wire feed rate and welding speed) based on four quality responses (deposition efficiency, bead width, depth of ...
