(they form a knife handle that holds the tang of a knife, sandwiched
between them).

I need to weld them together with TIG and my question is how. Again,
6061, they are 1/4" thick. What filler is best to use and what
amperage. Should I use lanthanated?

If the material is butted together, you should just be able to fuse them
together. A bit of polishing when done and probably wont even be able to
tell they were welded.. If you need filler, then I would suggest the
same type of material.

that says to use 190-220 amps
