Optimization of Welding Input Parameters Using PSO Technique for Minimizing HAZ Width in GMAW

In order to conceive command systems for welding equipment based on intelligence techniques similar human thinking; it is better use artificial methods, example: Genetic algorithms and particle swarm optimization. Freshly, this latter has received increased attention in many research fields. This paper discuss the application of optimization algorithm optimize process parameters obtain a Width Head Affected Zone (WHAZ) machine which gas metal arc welding. The effect four main variables process, namely speed, voltage, nozzle-to-plate distance wire feed speed WHAZ are studied. A source code developed MATLAB 8.3 perform
