  In this paper, I develop the Soldering formalism in a new domain - the
noncommutative planar field theories. The Soldering mechanism fuses two
distinct theories showing opposite or complimentary properties of some
symmetry, taking into account the interference effects. The above mentioned
symmetry is hidden in the composite (or soldered) theory. In the present work
it is shown that a pair of noncommutative Maxwell-Chern-Simons theories, having
opposite signs in their respective topological terms, can be consistently
soldered to yield the Proca model (Maxwell theory with a mass term) with
corrections that are at least quadratic in the noncommutativity parameter. We
further argue that this model can be thought of as the noncommutative
generalization of the Proca theory of ordinary spacetime. It is well-known that
abelian noncommutative gauge theory bears a close structural similarity with
non-abelian gauge theory. This fact is manifested in a non-trivial way if the
present work is compared with existing literature, where soldering of
non-abelian models are discussed. Thus the present work further establishes the
robustness of the soldering programme. The subtle role played by gauge
invariance, (or the lack of it), in the above soldering process, is revealed in
an interesting way.
