Cutlass manufactures and sells stud welding products for a variety of stud welding applications.
After reviewing the chart below, use the links above to take you to the stud
welding process which appears to best fit your application requirements.
CD or ARC Process?
Cutlass manufactures two distinct stud welding methods: Capacitor Discharge (CD) or Drawn Arc (ARC).
CD is generally used for smaller stud diameters up to 3/8" and is used primarily when welding to thin sheet metal.
ARC is generally used for stud diameters of 1/4" and above and when welding to thicker base materials or in structural applications.
There is obviously an overlap between the two systems, however application areas are normally well defined...
the following additional criteria may need to be considered when choosing a stud welding system:

Resistance Weld (RW) screws are not welded with standard stud welding equipment.
They are normally attached using a resistance or spot welder.
Materials used for stud manufacture are identical to those used for ARC studs.
However, unlike ARC studs, heat treatable steel alloys can also be used, the most popular of which is a steel alloy with added Boron.
Studs manufactured from this alloy can be heat treated after manufacture to grade 8.8,
with ultimate tensile of 113,800 psi (785Nmm) minimum.
