Goodbye to Burn-Through in Welding: Pulsed Welding
In another area, Alum-Line made long TIG welds on .080-, .100- and 1/8-inch aluminum diamond plate. Here, the operator fought warping. After switching to pulsed MIG, the operator increased travel speed by 30 percent, maintained good bead appearance (see Fig. 1, Bead Comparison) and solved warping issues by reducing heat input.
