Influence of welding wire voltage on surfacing forming
Effect of Welding Voltage of Cored Wire on Weld Forming
First, the arc voltage is too large and cause spatter
Second, the voltage is very low cause wear-resistant wire Like a firewood-like heap on the weldment, the wire into the molten pool and touch the bottom of the melt pool of unmelted base material
Third, the use of larger current, higher voltage can be used without generating pores. With the highest voltage available, the weld bead formation can be used for a variety of purposes.
Fourth, the arc voltage increases the weld bead flattening and widening
Fifth, reducing the arc voltage may result in the appearance of the rope with the shape of the weld
