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.

You can't get 6061 filler rods. Use 4043 or 5356.

that says to use 190-220 amps

Shouldn't need that much, just to hold 'em together.

6061 CANNOT be welded without adding filler rod. I have the magizine
article at home. That's why there is no such thing as 6061 filler
rod.

Thank You,

6061 CAN be welded without filler, but it does not make a real good
job, and using strips of 6061 sheet DOES work in a pinch - when you
want the weld to totally dissappear when ground down and polished.

Just so, which I'd think would be the objective with an ally handle
encasing a blade.

This not some kind of an art piece. This is a very big kitchen knife
with a very thick handle. My FIL uses is to, like, split frozen meat
and such etc. So I want a handle that would survive pretty extreme
abuse and would be relatively pleasant to hold.

This is rapidly becomes a big dollar project due to the time spent,
materials wasted etc, broken drill bits but I treat this as a if it
was a fee for getting education.
