There are three types of stud welding processes: Capacitor Discharge (CD), Short Cycle (SC) and Drawn Arc (DA).
Each of these Stud Welding Processes are complementary and should not be regarded as alternatives. Typically in a production line you would chose the correct process based on your design needs.
With each method, a weld stud is held in a hand tool or production head, it is then presented squarely to the work piece and a weld occurs without breaking through the material.
With the Capacitor Discharge Process energy is stored in a bank of capacitors, which are charged to a pre-set voltage, determined by the type and size of stud and the parent material. When triggered...View CD Process
A transformer rectifier supplies a fixed current power source, triggering produces a pilot arc and the stud lifts to a pre-set height.The main arc melts the end of the stud, producing...View SC Process
With this process, the current level and weld duration are determined by the stud diameter. Triggering produces a pilot arc and the stud lifts to a preset height. The main arc melts the end of the stud, producing a molten...View DA Process
