Stud Weld Processes

What are the types of Studwelding Processes?

There are three types of stud welding processes: Capacitor Discharge (CD), Short Cycle (SC) and Drawn Arc (DA).

  • Capacitor Discharge (CD)
  • Short Cycle (SC)
  • Drawn Arc (DA)

Which Studwelding Process?

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.

  • Not-Interchangeable
  • Complimentary Processes
  • Application Dependant

how it works

How The Studwelding Process Works

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.

  • First Stud is Loaded
  • Stud 'pip' is Offered to the Job
  • Can be Handheld or Production Head
  • Weld occurs without damaging parent material

Stud Welding Processes

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...

Capacitor Discharge 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...

Short Cycle 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...
