Short cycle stud welding [3] is a faster form of drawn arc stud welding which can use capacitor discharge weld studs instead of drawn arc studs. This method can tolerate welding studs to thinner sheet metals than the drawn arc process, though it does not achieve welds that are as strong or penetrative.
Friction stud welding is a solid phase welding technique involving a stud or appurtenance being rotated at high speed while being forced against a substrate, generating heat by friction. The metal surfaces reach a temperature at which they flow plastically under pressure, surface impurities are expelled and a forged weld is formed.
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
ISO 14555 is an ISO standard for arc stud welding of metallic materials.It was incorporated as a European Norm as EN (ISO) 14555 and is referenced by Eurocode 4 in the evaluations of the design shear resistance of a headed stud which is automatically welded according to this standard.

Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.
