^ Marine Welding is a Tough Job
Welding is the ultimate permanent fastener, connecting materials at the molecular level and endowing joints with tensile strength, toughness, hardness, and ductility similar to that of the bonded materials.
Van der Willingen formulated waterproof electrodes in 1946 and harnessed the long-known potential of electric arcs to weld under water. British Admiralty first executed marine welding for ships.
Industrial welding engages diverse processes. Marine welders prefer arc welding because the flux or inert gases used in the process protect the molten weld pool. Steel remains the most welded material, above or below water. Read More
