The Influence of Welding Parameters and Processes on Weld Beads
I. The Influence of Welding Current, Arc Voltage, and Welding Speed on the Weld Bead 1. Welding Current: When the welding current increases (with other conditions remaining unchanged), the weld penetration and reinforcement height both increase, while the weld width remains unchanged (or slightly increases). The reasons are as follows: ① After the current increases, both the arc force and the heat input on the workpiece increase, causing the heat source to shift downward and resulting in greater weld penetration. The relationship between weld penetration and current is approximately linear. ② As the current increases, the amount of wire melted increases nearly proportionally. Since the weld width remains roughly constant, the reinforcement height consequently increases. ③ After the current increases, the diameter of the arc column expands; however, the depth to which the arc penetrates into the workpiece also increases, thereby limiting the range of movement of the arc spot.
