All engineering and manufacturing processes depend on welding at some point. The heating and joining process works more reliably than any other fabrication process. Among the many methods that can be employed in this procedure is stud welding.
Here is everything you need to know about stud welding.
Stud welding is the single-side fastening method used in joining a metal part to tapped studs or weld pins during an arc welding procedure. The sections are joined permanently using an electric discharge of gas at high speed. The arc discharge generates heat at extreme temperatures between the workpiece and the stud, melting them into one. The stud becomes part of the molten pool, forming a secure fusion with the workpiece.
Advantages and applications of stud welding
It’s a clean type of welding: The melting and fastening are done on one side of the metal part. The procedure does not leave visible marks on the reverse sides. This the type of welding, therefore, finds ready use in decorative and consumer applications such as fixing panels, signs, badges and pins to jewelry or handles to doors
Flexibility: Stud welding can work with a limitless variety and sizes of metal and studs. You can leverage the procedure when working with aluminum, stainless steel, brass copper and many others that you want stud welded fast and aesthetically. You can use both threaded and unthreaded studs of different diameters. The procedure is thus highly applicable in mechanical operations such as fixing fluid lines or attaching handles to machinery.
Precision due to easier access: Welding technicians do not need to work at impossible angles to fix the stud to a metal part. Since they are working from a single side, it's easy to weld the fastener in place with a high level of accuracy even when dealing with hard to reach areas. This welding technique, therefore, comes handy in fixing electrical components to panels and mounting switches and push-buttons.
Leaves no holes: Other fastening procedures for fixing studs on metal parts such as drilling leaves holes. That often requires a finishing procedure to seal the holes. Stud welding solves problems such as corrosion, the risk of leaks and general structural weakness in the various applications of the workpiece. Stud welding, therefore, comes highly recommended for fixing pipes or insulation materials.
Speedy and productive: As hinted earlier, this is the fastest fastening technique for studs on metal parts. This procedure can create more than eight studs per minute granted you use a state-of-the-art tool. That means that whatever application you are leveraging it for, you can expect higher productivity and accelerated delivery time for the project.
The stud welding procedure involves heating both parts of the metal workpiece and the fastener with an electric arc. The welding procedure is one-sided and doesn't create marks on the reverse side. The arc welding technique can be divided into two types: arc stud welding and capacitor discharge stud welding. In the drawn arc technique of arc stud welding, the fastener is in close contact with the workpiece. The welding gun is placed in direct contact with this stud, and when it is fired, a direct current flows from the gun to the stud. The energized stud lifts and draws the arc required to melt the workpiece. When enough arc is drawn, the lifting mechanism stops, and the stud falls into the molten pool—the stud and workpiece are joined, and the two solidify in a sturdy weld.
The drawn arc technique is more useful for sheet thicknesses that exceed 2mm. It works well with studs of diameters between 2 and 22 mm. A flux material embedded in the stud helps to keep the welding area free from atmospheric contamination during the procedure.
The short arc technique works in many ways like the DC-powered drawn arc welding procedures. However, it uses neither flux nor ferrules, and the welding process is much faster. The short arc welding equipment and studs are also much cheaper compared to other stud welding techniques.
Capacitor discharge welding is used where joints must be seamless together with non-existent marring on the reverse side of the workpiece. The CD stud welding technique works more effectively on materials such as aluminum, mild steel and stainless steel—they are cleaner and flatter.
Capacitor discharge welding is more useful for thinner materials of about 0.7 mm in thickness. The stud diameters used are also much smaller than those for arc stud welding, the maximum size is 1 mm. CD stud welding is similarly one of the fastest and least expensive methods of fastener welding.
Welding symbols are used in blueprints to communicate between the welder and the designer. You will see them in most design plans for welding and manufacturing projects. The standard welding symbol comprises of an arrow, a leader line, a tail, a straight reference line, and a weld symbol
The stud weld symbol uses the weld symbol only on the arrow side of the surface joint. Size and pitch are placed on the same side as is the case for sport and seam welds.
Like every procedure in manufacturing or engineering, there are international standards to abide by in the stud welding process. Working by the standards guarantees a safer and superior quality output in your welding projects. The general ISO (International Organization for Standardization) stud welding requirements include:
Studs must be of proper design for arc welding. The size and type of studs must be specified in drawings and specifications.
An arc shield of heat-resistant ceramic shall be furnished with each stud.
Only studs with the right stud bases shall be used.
Finishing shall be by rolling, heading or machining and finished studs should be of uniform quality and condition.
Ferrules are the protective and heat shielding rings used to cover the studs during the welding process. They're used in many applications besides stud welding. Ferrules prevent porosity and atmospheric contamination of the joint during the welding process.
Ferrules also contain the molten pool and keep it from spreading outward. Your metal and fastener will have enough molten to fuse robustly and neatly. Some types of ferrules also act as UV shields, protecting the surrounding area and the arc from the damaging rays.
Stud welding is one of the fastest and most reliable procedures for securing fasteners on metal parts. Unlike other welding or stud fastening procedures, stud welding guarantees speed without compromising the robustness of the resultant joint. The bonds formed can last a lifetime.
