do you always have to use filler rod

im welding some pilot heads for a burner with 1/16 tungsten and 1/16 filler and #6 cup. 3/32 stainless butt joints the beads are very small an filler makes the bead even bigger.Its like taking a 2 an 1/2 inch pipe and put a washer inside and a coupling in the center of the washer and weld them at the top so it is as flat as possible. any suggestions. Thanks,

I dont fully understand your joint configuration but the title of your post is about whether its necessary to use filler rod.

The answer is not always simple but no you do not always need to use filler.

Stainless steel kitchen equipment is often done without filler rod.
