The arc-welded elements are used in heavy carpentry when a particularly safe welding is required, in addition to welding stud bolts, weld-on threaded bushes and other items included in the catalog are available. The most known drawn arc welding is drawn arc welding with ceramic ferrule where an electric arc happen between the stud and the component to which it is welded, thus obtaining a complete fusion between the two.
Ceramic ferule has the function of protecting melt from oxidation and slowing down the cooling, after which it is crushed.
Another drawn arc welding is drawn arc welding by gas protection used for diameters up to 12mm where it is possible to weld studs without the ceramic ferule, protecting the welding with inert gas.
Another type of drawn arc welding is the short cycle stud welding used to weld studs up to m8 on thin sheets by obtaining a stronger welding than the condenser discharge welding.
