CNC stud welding machines can increase the speed and accuracy of manufacturing and construction work. Stud welding is versatile; typical applications include automobile bodies, electrical panels, shipbuilding and building construction. Shipbuilding is one of the oldest uses of stud welding, and the process revolutionized the shipbuilding industry.
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.
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.

Friction welding (FWR) is a solid-state welding and bonding process that generates heat through mechanical friction between workpieces in relative motion to one another. The process is used with the addition of a lateral force called "upset" to plastically displace and fuse the materials. [1]
In the automotive body repair industry before the 1980s, oxyacetylene gas torch welding was seldom used to weld sheet metal, since warping was a byproduct as well as excess heat. Automotive body repair methods at the time were crude and yielded improprieties until MIG welding became the industry standard. Since the 1970s, when high strength ...
As with their air-actuated cousins, powder-actuated guns have a muzzle safety interlock. If the muzzle is not pressed against a surface with sufficient force, the firing pin is blocked and cannot reach the load to fire it. This helps ensure that the gun does not discharge in an unsafe manner, causing the nail to become an unrestrained projectile.
In such application, where the gun layout should be as rigid as possible due to the high applying forces (e.g. welding of thick materials), the C-type gun is widely used. As well as the high resulting rigidity, this arrangement leads to a high tooling flexibility, as the motion of the electrodes is collinear.
