Capacitor Discharge Resistance Welders (CD Welders) FOR SALE at Weld Systems Integrators
Perfect for Projection Welding of Fasteners to Hot Stamped Boron and Press Hardened Steel
What is Capacitor Discharge Resistance Welding?
Capacitor discharge resistance welding, sometimes referred to as capacitive discharge or CD welding, stores energy from a capacitor bank for extremely fast release of energy with large peak currents. Using stored energy, welding times are short and concentrated. This results in more energy into weld formation and less into heating the surrounding material. Furthermore, the heat affected weld zone, where the properties of the metal have been changed is smaller. This minimizes changes in the metallurgy of the workpiece.
Weld Systems Integrators, a capacitor discharge welding machine manufacturer, has proven results and welding solutions for tough-to-weld materials and applications.
Weld Systems Integrators manufacturers capacitor discharge spot welding machines for a variety of processes, including projection welding of fasteners to hot stamped boron steel. We manufactured our first capacitor discharge resistance welder in 2007. That CD welder is still in production today. And continues to make great welds and great parts. Through the years, we’ve had OEM’s, Tier 1 and Tier 2 suppliers bring parts to our Welding Lab and we have demonstrated consistent results.
Types of Capacitor Discharge Welders include:
Stand Alone Pedestal Capacitor Discharge Welders
- Single Stationary Head
- Two Selectable Head Configurations
Multi-Station Capacitor Discharge Welders
- Two Selectable Head Configurations
