There are many different applications that offer a perfect match for the use of a CD (Capacitor Discharge) stud welding system. In general, the CD stud welding process works best with smaller diameter weld studs and for use with thin workpieces.
Common applications for the use of the CD stud welding process include in assembly and fabrication of electronic components including pumps, electric motors, computers and communications devices and equipment. This is also the processed used in making jewelry, as well as for small tools and hardware and kitchen items such as pots and pans as well as kitchen and cooking utensils.
As this is an extremely fast welding process, taking less than six milliseconds per weld, doesn’t build up a lot of heat, so there is no marring or distortion of the opposite surface of the material.
Also, the fast process means that there is no need to use flux or any shielding gas when installing CD weld studs, which makes it a very simple process.
Options to Consider
There are two different types of CD weld studs used in most applications. The most commonly used general type of weld stud is the full thread. This is a literal description of the stud with the thread from top to bottom. This allows for easy attachment of the part and the ability to tighten down the nut to the desired position down the shaft of the stud.
The benefit to this is one weld stud can be used for thicker as well as the thinner parts. There will always be threading to the exact position required regardless of the dimensions of the parts being mated.
There are also non-threaded CD weld studs. These are also self-explanatory, and they care completely non-threaded. These weld studs can be used as locators or even as handles, and they are durable, strong and will last much longer than other types of hardware.
The third type of weld stud for CD weld system is the pitch diameter. This has a non-threaded component and then a thread of a specific length down the shaft. These are ideal for attaching specific parts of known and consistent thickness.
