Artech welders

Beyond welding. Technology that improves your product.

Capacitor Discharge Welding. Current up to 200,000 A. Weld time of less than 10 milliseconds. 70% lesser power requirement, compared to conventional projection welding, remains the most important advantage of Capacitor Discharge welding.

Capacitor Discharge (CD) Projection Welding

In CD Projection Welding the weld area and location is pre-defined by giving a small projection (1 to 4 mm) on one of the weld components. During welding, the projection collapses under the electrode pressure and very high current passing through the electrodes fuses, the metal fuses to create the join. With weld time of less than 10 milliseconds and focused discharge of weld energy,

the heat does not conduct beyond welding area leaving the welded parts clean and distortion free.

The CD Projection welding can be performed on a multiple projections, simultaneously. The work-pieces are pressed at the projection using pneumatic/hydraulic or servo motor drives.
