The Associated Society of Shipwrights was formed in 1882. At some time between 1900 and 1910 it absorbed the Ship Constructive Association, along with many local societies, and changed its name to the Ship Constructors' and Shipwrights' Association. In 1909 it absorbed the Amalgamated Drillers and Hole Cutters' Society and in January 1963 it amalgamated with the United Society of Boilermakers, Blacksmiths, Shipbuilders and Structural Workers, to form the Amalgamated Society of Boilermakers, Blacksmiths, Shipbuilders and Structural Workers. In 1982 this society amalgamated with the National Union of General and Municipal Workers to form the General, Municipal, Boilermakers and Allied Trades Union.
