Optimization of Flux Cored Arc Welding Process Parameters Using Particle Swarm Optimization Technique

In weld cladding applications, most of the engineers are often facing the problem of optimum selection of input process parameters to achieve the required dilution. This problem can be solved by optimizing the process parameters. This paper focuses on an optimization of flux cored arc welding process parameters, which are used for deposition of duplex stainless steel on low carbon structural steel plates. Experiments were conducted based on central composite rotatable design and mathematical models were developed using multiple regression method. Further, an optimization of percentage dilution was carried out using particle swarm optimization technique. A computer program was developed using C language for computation of algorithm. It is highly reliable, adoptable, very user friendly and it can be extended to other welding processes such as GMAW, GTAW, Robotic Welding, etc.
