Improved Quality of Brake Pedal Welding Connection Using GMAW Process
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.
