Abstract
We give a quotient of the ring $\small{{\mathbb{Q}}[A^{{\pm}1},\;t^{{\pm}1]}$ so that the Miyazawa polynomial is a non-trivial invariant of welded links. Furthermore we show that this is also an invariant under the other forbidden move $\small{F_u}$, and so it is a fused isotopy invariant. Also, we give some quotient ring so that the index polynomial can be an invariant for welded links.
