The effect of process parameters on penetration in gas metal arc welding processes

Abstract

The welding currents were chosen as 95, 105, 115 A, arc voltages were chosen as 22, 24, and 26 V and the welding speeds were chosen as 40, 60 and 80 cm/min for all experiments. As a result of this study, it was obvious that increasing welding current increased the depth of penetration. In addition, arc voltage is another parameter in incrimination of penetration. However, its effect is not as much as current's. The highest penetration was observed in 60 cm/min welding current. (c) 2005 Elsevier Ltd. All rights reserved.
