Welding question

[dieselpilot1969]

What can weld Titainium, I have a mig, A buddy has a tig. Will either work?

 

[Paychk]

TIG is the most common option, I don't think that MIG is an option for this type of material

Titanium can be MIG or TIG welded. Any filler metal or wire should be the same material grade as what is being welded. You can subsitute lesser quality in a pinch, but it's not recommended.



The joints have to be super clean---clean beyond any realm of cleanliness ever before seen in welding. Very clean. :-laf



Nitrogen, oxygen, and hydrogen cannot under any circumstance be introduced into the arc or puddle--titanium reacts with these gases in it's molten state and becomes very brittle. 99. 99% pure argon shielding gas with a dew point -50*C (very, very dry) or lower is pretty much a requirement.



Anytime you stop the arc you must continue to shoot shielding gas on the bead/puddle until it cools from a red hot/molten state, and trim the oxidized end of the filler metal or wire before starting again--otherwise you'll ruin the bead.



In a nutshell... .....

well put... spent some time under the hood frequently have ya? I couldnt have put it better myself. Oh and use the biggest TIG cup or gas lens possible! Titanium becomes very "sticky" when you weld it. You'll see what I mean when you do it. Good luck
