Titanium welding specs

Titanium welding specs

(OP)
Hi, i'm not a welder but will be providing drawings for welding.  i was wondering if i could get some basic specifications for welding titanium tubes.  thank you.

RE: Titanium welding specs

You might try looking at D17.1 to see if that will cover what you want.

I'm designing a bike frame so the tubes will weld to the outer face of another tube.  I'm looking for strength.  The alloy will most likely be Ti-3AL/2.5V

I suppose TIG welding would be good enough for the cost but how to spec the weld so to get a quality weld is what i'm looking for.  

i'll see if the libraries carry the D17.1 specs
  

RE: Titanium welding specs

The following are some links for more information on welding titanium.  Only one of them is a specification.  There is an additional section of the Timet website that discusses welding of Ti tubing, but it is not available as a .pdf, so you will manually have to scroll through the pages.

RE: Titanium welding specs

You can also try titanium.net , this is the home of ITA.
You need to address a number of issues, not limited to; joint prep, cleaning, filler, welding control, and testing.  You will want to pay a lot of attention to testing.  Testing will be critcal.  Both the destructive testing to qualify a process and the nondestructive testing to assure good quality in production.
