Optimization of Double-Passed Welding Parameters on Butt Joint using Taguchi Methods

Abstract

This paper presents an investigative study of double-passed welding parameters on single V butt joint. In this study, a robotic welding system ABB IRB 2400/16 with digital welding power source KEMPPI Pro Evolution ProMIG 540 MXE are used to investigate the effect of parameters such as current, voltage, welding speed and width of weaving movement on distortion by using one-sided clamping method. The material used is low carbon steel with 6 mm thickness. Mix gas Argon 80% and Carbon Dioxide 20% is utilized as a shielding gas media. Taguchi method in MINITAB software is applied to manage the experiments and develop the relation between welding parameters. The results of this study will be useful to identify the problems by using robotic welding system and to obtain suitable process parameters for achieving good welding quality and effective welding design.
