Abstract

Factorial technique is a statistical method used for designing of experiments. This paper contains various techniques generally used in designing the experiments, their merits and limiations. It has included the system of designing of five level Factorial technique with four welding variables to be used for PULSE MIG HYPERBARIC welding. Finally, the application of Factorial design to study the weld bead geometry and shape relationship has been explained.
