    Tig weld "discolored"

    Hello... I have a silly doubt, welding stainless steel pipes and using different post gas times we have some colors like blue gold purple etc that you know... I know that best weld have plate gold colors but it isn't the question...
    When I have colored weld like rainbow if I touch weld with my finger it's come to be discolored... That is normal?
    Like I said it's only a doubt...

    Sorry for my bad english.

    Discolored how? If you are dipping the tungsten, it could leave an orange-ish residue on the metal. Otherwise I am not sure what that is you are getting on your fingers.

    Nice magic trick but Ya thats Normal. I figured that’s what u were talking about. As long as u don’t touch it that’s should stay colorful for a long time.

    The coloring is very thin oxide layer on the surface, the thickness of the oxide layer determines the color. From non-existent to heavy the colors vary from silver to gray with a progression through straw, gold, blue, purple as the layer gets thicker. Wiping it with your finger just removed the thinnest areas of oxidation and left the purple thicker layer mostly intact. It's normal and common for stainless welds to be polished after welding to remove the colors.
