Most people believe that there is only one welding application. However, in actuality there are different welding applications. One of the many welding applications is the stud welding application. In this process, a bolt is welded on another metal piece. This welding process includes utilizing stud welding equipment to feed the bolts in the spot welder.
Stud welding involves joining the stud for a flat plate and utilizing the stud as an electrode. The polarity, which is selected for the specific stud welding application, can depend on the kind of metal that is utilized. For instance, aluminum needs direct-current electrode positive and steel demands direct-current electrode negative.
The weld nuts that are utilized in stud welding process usually have flange with some kind of small numbs which melt during the process to form the weld. Another important aspect of this kind of welding process is the utilization of flux known as ferrule. A ferrule is a ceramic ring, which can concentrate the generated heart protecting oxidation as well as retaining the melted metal in the wished weld zone.
One specific kind of stud welding process is capacitor-discharge welding that differs from conventional stud welding. In that, it does not need flux. The process makes use of direct-current arc from capacitor. It takes time between a 1 and 6 milliseconds. As welding time is very short on capacitor, discharge welding then welder is able to finish the bonding with small oxidation and not real requirement for heat concentration. We will now discuss about weld studs.
Stud welding systems utilizes weld studs as a part of this well-organized application. The tips on the weld end of stud serve two purposes. The tips always act as a timing device, which can keep the studs off the base material, which is being welded.
Weld end tips fall apart once the trigger is pulled on welding gun, solidifying, melting the weld in the base material. Arc studs are loaded with an aluminum flux ball on the weld that can help to promote the welding process. These wonderful studs are an integral part of stud welding equipment. They range from a#8 to 1 ¼” diameter stud. Stud welding is an attractive option as it saves your valuable time. With conventional welding , it will tale numerous minutes to create this bond. The speed of this process means we can do more projects in short period of time. stud welding reduces the operating costs as well. Simplicity is the most appealing feature of stud welding process.

you got some good points, but I am not really convinced of this. And i got to much confusion in my life at this moment to spend longer on it. I may check back to see your postings.
