There are three types of studwelding:
a handtool or production head-then presented squarely to the work piece. The three process's work as follows.. ( There are other types of stud welding mostly industry related - should you require information .call our office) Capacitor Discharge M2.5 to M10 dia Energy is stored in a bank of capacitors charged to a pre-set voltage determined by a type of stud and parent material. When triggered, energy discharges as a high current pulse, melting the pip to produce an arc. Spring pressure forces the stud onto the molten surface to ensure complete fusion across the flange. Weld duration under 4 millisecond Short Cycle M2.5 to M8 dia A transfer 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 a molten pool in the parent material. Return spring pressure then forces the stud into the pool. Using a shrouding gas reduces weld spatter especially with stainless steel. Weld duration: 10 to 100 milliseconds Drawn Arc M5 to M25 dia Current level, and duration are determined by the stud diameter. Triggering produces a pilot arc and the stud lifts to a pre-set height. The main arc melts the end of the stud, producing a molten pool in the material. Return spring pressure forces the stud into the molten pool. A ceramic ferrule contains and shapes the weld fillet, this arc shield is not re-usable. Weld duration: 100 to 10000 milliseconds |
