Aluminum Stud Welding with Tip Ignition - Threaded Stud - Type PT

Material: Aluminum

Standard: DIN 32501 (-1) - 1991&ISO 13918 (PT) - 1998

Aluminum CD (capacitor discharge) weld studs with ignition tip

DIN EN ISO 13918-PT

CD (Capacitor Discharge) Fasteners have a small pip under the weld end, which melts during the arc and welds the end of the fastener to the material. This is assisted by spring pressure from the welding gun.

The process is completed from one side only, leaving a smooth and usually unmarked reverse side due to the shallow weld penetration depth.

Aluminum studs are more lightweight than steel or stainless steel studs. They’re nonmagnetic. In wet environments, they resist corrosion.

The material mix in modern lightweight vehicles is seeing highly rigid steel or noise suppression plates being used increasingly.

Welding studs with spot-shaped flanges cause stability problems; in noise suppression plates, a layer can be melted through, damaging the plastic coating.

Instead of using expensive insert nuts, rivets, or screw solutions, Its extensive contact surface guarantees previously impossible transferability of torque and other resistances.
