I want to permanently attach 3/8" diameter rods to 3/8" rods end-to-end and
was looking for advice on the best way to accomplish this. The methods I'm
considering are welding, tapping, or use of a roll pin.

The rods will only be about 3-1/2" long, and the pieces that I want to
attach are 1/2" long.

Perhaps a combination of the attachment methods mentioned for this rod
extension project would be warranted.

Any advice would be appreciated.

Thanks.

You could friction weld the parts in your lathe.
