I think so
The main purpose of the adding filler rod is to remove the contaminants in the form of slag and to maintain the shielding around the welding operation and giving extra strength to the metal to be welded.so as per my knowledge filler rod should be coated with any alloy or any thing(required metal in the form of powder) inorder to form a slag..Suppose if you dont want to add any filler metal then try add some shielding inert gases for shielding to secure the health of human beings who is doing the particular job
