WebCompared with P-GMAW, double-pulsed GMAW (DP-GMAW) has wider adjusting range of parameters, so that the wire feed rate is easy to control [62]. The DP-GMAW can be considered a means of increasing productivity without the drop in quality. Fine weld joints with natural ripple surface are obtained with this high production efficiency welding ... With pulsed MIG welding, it’s possible to use larger-diameter welding wire. This is because the lower amperage better controls the current, allowing a larger wire to be used on the same material thicknesses where normally a smaller-diameter wire would be required.
