I have a drawing for an inconel 718 component that has a dowel pin welded into it using ASM51G filler material. I haven't been able to find anything remotely like that on the net and was hoping someone here may be able to enlighten me.
You might ask http://www.usweldingcorp.com/main.htm, they deal with a lot of "aerospace" alloys. Also http://www.haynesintl.com/, manufactures alloys such as IN-718.
