Stud Welding
A rapid arc or drawn-arc capacitor discharge process where metallic studs are melted across their entire cross-section and pressed onto a base material. It is used for the efficient attachment of threaded elements.
In stud welding, you strike an arc between the stud and the base material, which melts the stud end and then presses it onto the workpiece with pressure. The settings must match the stud diameter and sheet thickness – if you use too much energy, you burn through or get spatter; if too little, the joint won't hold. Make sure the contact surfaces are clean and rust-free, otherwise you'll get porosity. The process is simple: insert stud, position, trigger, done – but the parameters need to be properly set for each material combination.
