Ross,

It should be TIG welded. It is an easy job for most any good welder with a TIG machine. I could do it for you if you care to mail it to me. If not make sure that who ever you have do it bewvels both pieces so that the weld is full penetration. The root pas should be allowed to cool completely before the final pass. If they don't it will shrink in length possibly as much as 1/16". Finally make sure it is aligned and straight before welding.
