STUD-WELDING A TECHNIQUE FOR USE IN SHIPBUILDING

After giving some general information on stud-welding and its industrial applications, the Author describes some shipbuilding applications where the method can be used to advantage. In the shipyard, stud-welding has been primarily used for welding threaded studs on to plating etc. for the attachment of various fittings such as man-hole rings, cable and pipe hangers, and much else. Another important use, introduced later, is in the lining-up of joints for welding; in this application, the studs are used for securing strongbacks in some American yards, and for securing wedging-shoes in European yards; the strongbacks and shoes are re-usable. The studs have several other uses in the temporary fixing of reusable equipment. For wedging joints to be welded in shell plating, the studs can be welded on to the inside of the plating during prefabrication; they can be left in position after the wedges have been removed. The studs are also used for anchoring hydraulic aligning equipment for joints between large hull sections. French shipyards have developed high-strength aluminium-alloy profiles, secured by stud-welded studs, as an alternative to steel strongbacks or wedges for use in joint alignment. The profiles can also serve for accommodating the ceramic backing in one-side welding. The article includes a list of particulars of the studs used with joint alignment equipment, and mentions that as this application is at an early stage of development, new types of studs will be forthcoming.
