While some people assume that CD or Capacitor or Capacitative Discharge welding is only used for lightweight types of hold requirements, this is really not the case. The use of CD welding is based on short weld times, which allows for thin base pieces to be used in the process. The weld itself is incredibly strong and is capable of standing up to demanding environments and applications.
The short weld times are paired with slightly smaller CD studs that can be used with the drawn arc stud welding process. However, the speed of the weld is essential to avoid marring or burning the other side of these thin base metals, which can be as fine as 0.02 inches in thickness.
There are several types of CD studs that are used in these applications. Choosing the right option is really a case of understanding what is needed and making the selection.
Threaded weld studs are used for a wide variety of applications. These CD studs allow for the base material and the second material to be mated using a nut to fully snug down the two materials.
As with any stud welding, this can be completed without any marking or burning to the other side of the base piece of metal. The studs are designed to have threading from top to bottom, providing a versatile option for any type of fabrication and manufacturing requirement.
As withdrawn arc non-threaded studs, the CD options are ideal for use in a variety of applications. They can provide handles, stops, and locators and also provide options for quick, temporary placement of metal parts.
Easy to use with CD stud weld equipment, these can be applied with hand-held tools or with automated systems, making them ideal for a variety of fabrication and manufacturing requirements.
