Capacitor discharge studs are very useful in the welding process, particularly when it comes to welding aluminum. Unlike steel, aluminum conducts electricity much more efficiently; this can actually be problematic to the point where welding aluminum is virtually impossible without using capacitor discharge studs. Without using such studs, the heat is quickly dissipated away from the welding zone, resulting in a weld of unacceptable quality. The studs help to enable a high-quality weld when working with aluminum.
Capacitor Discharge Welding
Capacitor discharge welding involves using aluminum studs that range from 1/16 to ¼ inch in diameter. Weld energy lies within the capacitors; then, a small tip or projection at the end of the stud is what initiates the welding process. Without the capacitor discharge studs, there would not be enough energy to fuse the aluminum stud to the panel. The studs also help to ensure that the energy transference welds the aluminum to the panel without burning a hole through it.
Due to the fact aluminum conducts electricity so well, the welding process is very quick, as quick as 10 milliseconds in fact. It takes less than one second to weld a ¾-inch fastener. There are both threaded and non-threaded studs available, with threaded studs being a very popular choice for a wide variety of projects in many different industries (including food service, industrial, and more).
Other Benefits From Using Capacitor Discharge Studs
Due to the fact that using these studs shortens the welding time considerably, there is no need to use shielding gas or flux when attaining a good weld; a capacitor discharge welding is both effective and clean. Using such studs and achieving a high-quality weld quickly is especially useful in industries where rapid, high-quality work is essential to profitability and success.
