STUDY ON THE WELDMENT CHARACTERISTICS OF CARBON STEEL PLATE WELDED BY GMAW USING DIFFERENT CURRENT VALUES

Abstract

The purpose of this study is to identify the relationship between the current value of the Gas Metal Arc Welding (GMAW) process, and the characteristics of the weldment produced on the carbon steel plate. The characteristics that will be observed are the depth of the weld penetration and the rate of weld formation. The variable in this study is the current value of the GMAW process. This study uses carbon steel plates of thickness 9mm. The current value of the GMAW process will be increased gradually. Each of the carbon steel plate of different current will be welded to form horizontal weld bead. All the welding will be done in 1G (horizontal) position. This study will determine the best current parameter in welding 9mm carbon steel plates.
