Here is a photo that shows the weld mark. The work piece is 2.5" x 1.5" x 7/8" (14.4 sq in) in size and was anodized using the LCD process at a current density of 4.5 amps. The mark on the left is the weld mark which remained when the wire was snapped off after anodizing and dyeing. The crater is slightly larger than the 8ga aluminum wire which I used, as at the time it was the only aluminum wire I had available. Using 16-18ga wire would have resulted in a much smaller crater. The hole on the right is a .125" hole that I had initially planned to use as a mechanical connection point by tapping it and screwing the 8ga wire into it.
