Energy storage welding stud positioning

What is energy storage welding?

Energy storage welding is most commonly used for welding studs with smaller diameters. The principle involves the release of stored energy from a capacitor at the moment the stud contacts the base material, causing the area where the stud and the base material meet to melt and weld together.

What temperature should a stud Weld be at?

at S355: +5°C The welding location must be adequately protected against rain and snow. Otherwise, welding must NOT take place. The “blow effect” (or “arc blow”) impairs the quality of the stud weld connection. “Blow effect” describes when the arc is diverted by external induction fields that mainly originate in asymmetrical current movement.

What is welding studs on a metal base material?

Currently, the process of welding studs onto a metal base material through various welding methods is widely used in electrical cabinets, home appliances, furniture, automotive parts, and various hardware sheet metal parts. These welding methods can generally be divided into two types: energy storage welding and arc welding.

What is stud welding?

Stud welding is a general term for joining a metal stud or similar part to a workpiece.1 Welding can be done by a number of welding processes including arc, resistance, friction, and percussion. The arc stud welding process (SW), including capacitor discharge methods, will be covered in this document.

How does a stud holder work?

The stud is slid into the stud holder with its tip placed on the workpiece and welding gun pressed down against the workpiece to the mount of the support tube. When the release button is pressed on the welding gun, the stud lifts and an auxiliary arc is created.

How do weld studs work?

When triggered, an electric solenoid in the gun lifts the stud to a preset height off the base metal. The drawn arc melts the base of the stud and the base metal, creating a molten pool. The gun then forces the stud down into the molten pool and the molten material is held in place with a ceramic ferrule until the weld is formed.
