The process became widely used with the introduction of smaller-diameter electrode wires and refined power supplies. The British primarily used arc welding, even constructing a ship, the Fulagar, with an entirely welded hull.
This in conjunction with developments in automatic welding, alternating current, and fluxes fed a major expansion of arc welding during the s and then during World War II.
