Titanium welding specs

[dubbed]

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.

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

Are these full penetration butt welds or tube to tubesheet welds (seal or strength?)?

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

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.

In designing welded structures there is more than what you might suppose.
You may wish to see the chapter 5 on Design for Welding from AWS Welding Handbook, 9th Edition Vol. 1

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.
