Flare Bevel void fill
Flare Bevel void fill
(OP)
If I need to weld two members together and has a large radius, can I specify a backer rod to fill in the void provided the weld attaches the rod to both members and extends over the top of the backer rod?

It's something else, and will behave differently than a flare-bevel.

Can you come back with some more information sizes and material?
A rod isn't normally used for a backing ring. Look at the site below for some acceptable shapes for backing rings.
Most codes require that if you use a backing ring you have to use a welding procedure that qualifies the use of same.

What you are proposing may prove highly similar to slugging a weld in actual practice, resulting in cracking and weld failure in service (depending on the service conditions). As a general rule, I would recommend against it.
