How to recognize, minimize weld smut
PRACTICAL WELDING TODAY® MARCH/APRIL 2003

When I weld any aluminum alloy, I see a covering, light gray to black in color, over the weld. I see it when I gas tungsten arc weld (GTAW), but it's worse when I gas metal arc weld (GMAW). What is it? Does it affect the mechanical properties of the weld? How do I get rid of it?

Armano is one of the best.

And a nice guy to boot.
