Re: 64' K10 Project Long Bed
Weld contamination in a sheetmetal weld is not as critical as in structural welding, but if severe enough can create a weld that will fail. You can check for porosity by grinding/sanding the weld down and see how it looks. The weld contamination can sometimes be minimized by using a smaller tungsten and filler rod and also changing the arc frequency and/or the pulse if the machine has those capabilities.
