In 1947, organizing and merging of local unions was a common strategy to increase the market share and increase membership. Local 455 merged with the metal trades workers on July 25, 1947. At that same time, the size of the local increased by adding the counties of Ramsey, Washington, and Dakota.

Total membership of Local 455 at this time was 150.
