why are some spots on the TIG welds blue and others not?

I am not sure as to the scientific reason but generally stainless steel will get that color or cold rolled steel when welded, if there is poor gas coverage or to much heat is applied the color will be dark grey or black. if the base metal is Titanium and you see color in the welds that is a bad thing. the weld is contaminated because of poor gas coverage. the best way to weld Ti is with the work peace in a argon gas filled chamber. another way is with a high flowing gas lens and another device covering the trailing welds with argon gas. of if your really good you can turn up the gas flow, angle the torch so that as your welding gas is not only covering your current weld but also your trailing welds.

^if I am incorrect someone please correct me

when I was first learning how to Tig I asked that same question about the color in the welds. i was told that its because i was doing everything right good speed,amount of filler added,correct amount of heat,and good gas coverage.

They can be 'pickled' to remove the bluing.

EDIT: I love the sway bar blades.

Took me a second to figure it out, then I saw the cable and it all made sense.

i need to learn how to weld big time.. i have so many things i want to make for my E30 and the only missing link is a welder. providing i had the time i could easily spend countless hours working on something millimeter by millimeter all day long, i do it already with other things. kinda like once u get going ur in the zone and dont want to stop lol
