(they form a knife handle that holds the tang of a knife, sandwiched

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,
