摘要：Pulsed gas metal arc welding is one of the most widely used processes in the industry. It offers spraymetal transfer at low average currents, high metal deposition rate, versatility, less distortion, and the ability to be usedin automated robotic welding systems. The weld bead plays an important role in determining the mechanical propertiesof the weld. Its geometric parameters, viz., width, reinforcement height, and penetration, are decided according to thewelding process parameters, such as welding voltage, welding speed, pulse current magnitude, frequency (cycle time),etc. Therefore, to produce good weld bead geometry, it is important to set the proper welding process parameters. Inthis project, mathematical models that correlate welding process parameters to weld bead geometry are developed withexperimental investigation. Taguchi methods are applied to plan the experiments. Five process parameters, viz.,welding speed, plate thickness, pulse frequency, pulse current magnitude, welding voltage etc and base material asstainless steel (SS grade 410) are selected to develop the models using multiple regression analysis. The modelsdeveloped were checked for their adequacy. Results of confirmation experiments show that the models can predict thebead geometry with reasonable accuracy
