Stud Welding is a type of electric arc welding where a fastener or a specially formed nut is welded on to another metal part, usually a metal base. The fastener/nut and the base can be made from various metals including steel, stainless steel, and aluminium. Weld nuts usually have a flange with small nubs that melt to form the weld itself. Fastener’s are usually threaded, unthreaded, or tapped, and bolts can be fed into a stud welder automatically.
The fastener or metal stud is joined to the metal base by heating both parts with an arc. Arc stud welding allows for maximum weld penetration and reliability for a variety of applications. It uses a DC powder supply to create the arc.
The Benefits of Stud Welding
Strength
The fusion between the two welded metals creates a weld that is stronger than the two metal parts independently. This allows it to withstand breaks and loosing.
Cleaner Design
As stud welding is a one-sided process. No holes are required so it’s possible to secure a stud weld without blemishing the structure. This gives a much cleaner design than other methods.
Speed
Each stud weld takes milliseconds which is likely why it’s used by so many industries. This vastly increases productivity.
Cost Efficiency
As stud welding is a faster method of welding it saves time and money. Stud welding also does not have the maintenance costs that often come with other welding types.
