Final answer:
The two basic types of stud welding processes are Capacitor discharge and arc stud welding. Capacitor discharge is a low heat method suitable for thin metal sheets, while arc stud welding is used for heavier applications with more heat penetration.
Step-by-step explanation:
The two basic types of stud welding processes are b) Capacitor discharge and arc stud welding. Stud welding is a method of attaching a metal stud to a metal workpiece through the use of heat and pressure. Capacitor discharge stud welding is a low heat method, wherein energy stored in capacitors is rapidly released to weld the stud onto the workpiece. This method is suitable for thin sheets of metal where minimal distortion is critical.
On the other hand, arc stud welding involves striking an arc between the stud and workpiece to generate heat. This is followed by pressing the stud into the workpiece, creating a strong and reliable joint. Arc stud welding is used for heavier applications where more penetrating heat is required. Neither cold and pressure welding, submerged arc and flux cored welding, nor flat and horizontal welding are considered the basic types of stud welding processes.
