that came out kind of cool. Been playing around with welding for a while and the welds still look a bit boogery, the patterns and colors it creates on the metal is something that I've always found pretty cool. Also been trying the macro lens that my wife has been using for a while.

Interesting stuff- wonder how the interference colours are made.

Not too sure. I've been told that that type of coloring occurs when the weld/or heat has penetrated the steel and the heat from the welder is correct. I'm still learning the basics but still having fun making "art"

that makes sense as I'm using a flux core wire on a small Harbor Freight welder.

The colours come from different levels of oxidation of the iron depending on temperature and environment (including flux).

There is a good (but technical) explanation here

Oxy-Acetylene? I tried it before and burned holes in many shirts :-P
Those colors are awesome.

try spraying this on the subject metal before you start to weld, it stops the weld spatter from sticking.

nice effect, keep practicing the welding, the more you do it the better you will get. listen for the nice crackling sound your welding makes thats when you know you are on the button.
i keep meaning to set up a shot of one of our guys at work in action but never get around to it.
