The influence of gas metal arc welding parameters on the carbon steel ss400 grade by using 23 actorial design
(0) The experimental observation reveals that the influence of gas metal arc welding process on physical properties.The specimen was carbon steel ss400 grade sheet of 6 mm.The experiments with 23 factorial design.The factors used in this study are voltage at 20 and 23 V, travel speed at 5 and 7 mm/sec and wire feed rate were set at 80 and 110mm/sec.The welded specimens were tested by penetration, width of weld metal and high of weld metal.The result showed that the voltage, travel speed and wire feed rate had interaction on penetration, width of weld metal and high of weld metal at 95％ confidential (P value < 0.05).Factors affecting the penetration are the most voltage of 23 V, travel speed 7 mm/sec and wire feed rate 110 mm/sec, were penetration of 31.68 mm.The width of weld metal was most at 9.9 mm.on voltage of 23 V, travel speed 5 mm/sec and wire feed rate 110 mm/sec. The factors affecting the high of weld metal are most voltage of 20 V, travel speed 5 mm/sec and wire feed rate 110 mm/sec, were penetration of 4.51 mm.This research can bring information to the foundation in choosing the appropriate parameters to gas metal arc welding process.
