Abstract
Welded brake pedal component connection using GMAW process with CO2 protective gas 100% contains spatter weld defects, weld-bead ripple, undercut and porosity at the level limit of 8.2%. By replacing 100% CO2protective gas with Ar 75% CO2 protective blend gas 25%, welding defects are reduced to a level limit of 0.88% dominated by spatters while other welding defects are virtually non-existless. Defective welding spatter with protective gas CO2100% shows a level of 2.77%. By using Ar 75% CO2 protective mixed gas 25%, defective welding spatters decreased to the level of 1.11%. Therefore, the replacement of protective gases in the GMAW process led to a 150% improvement in the quality of brake pedal welding joints. This will have an impact on improving the competitiveness of the industrial brake pedal components of two-wheeled motor vehicles.
