I saw one on the book of faces that was a Massive weave(4x wire dia. with 4 1/8" wires...) on a ~1/4" thick ~4"wide aluminium plate. They cut and etched it showing that it had penetration and no gaping porosity. Kind of a pretty weave pattern too... you could almost see how long the welder sat in one area...
It was all around pretty cool looking, but the claims that it was a strong weld (knowing the little I do about heat input and aluminium thanks to this forum) made me twitch a little...
End of the day, I realized I hang around you guys too much to get along with the "weld porn" crowd...
Ill try and find the pics... they seem to be lost to facebook, and I appearently didnt save them...
