New to Studwelding?

DA = Drawn Arc.

CD = Capacitor Discharge.

SC = Short Cycle.

These are three different types of studwelding methods in everyday use.
The menu above will guide you to the various section of our web pages where you will find more information for each process and products.

 
The Drawn Arc (DA) Process
Current and weld time is pre-set to suit the diameter to be welded

Current and weld time is pre-set to suit the diameter to be welded.
The stud is then placed on the plate.

The stud is then placed on the plate.
arcing takes place

Upon triggering a pilot arc occurs as the stud lifts to a pre-set height. The main arc then melts in the weld end of the stud and creates a molten pool in the plate.
spring pressure forces the stud

Return spring pressure forces the stud into the molten pool. The ferrule contains the molten metal and shapes the fillet.

 
Process

Very strong penetrative welds are achieved with this process. Ferrules required to contain and shape molten metal. Weld end of stud is fluxed
Studs

Stud Diameter 3mm to 30mm
Material

Material thickness 2mm & above
Power

Power Requirements 3 Phase 230/380/415V

Advantages

  • Burns through parent material laminations.
  • Tolerates surface curvature and imperfections, e.g. light rust, scale, grease and some coatings.
  • Gives neat and controlled weld fillet.
  • The only method of studwelding large diameters.
  • The Drawn Arc process also lends itself to multiple applications.
