Trim Head Finish Screws
Trim head screws are similar to flat head screws in both appearance and design. They have a circular head that is intended to finish flush with the surface of the material being fastened.
Continuous Thread Stud Bolts
Continuous thread stud bolts are versatile and robust fastening components designed for various industrial and construction applications. These bolts feature a continuous helical thread along their entire length, providing a secure grip and allowing for easy adjustment and installation.
Clamping Type Stud Bolts
Clamping Type Stud Bolts feature a clamping design, using nuts or clamping devices to secure and fasten threaded components. The product offers a variety of sizes and specifications to accommodate different application scenarios and thread requirements.
Tap End Stud Bolts
Tap End Stud Bolts are threaded rods with short thread length at one end, called the tap end for engagement with tapped machine hole, while the other end is longer for engagement with nut. Tap end studs are special stud bolts required for custom bolting requirement.
Steel
Steel is a great material to use for stud welding because it is strong, easy to work with, and inexpensive. It is suitable for the drawn arc stud welding and capacitor discharge stud welding processes. A lot of people use steel when they are stud welding because it is a sturdy material that has many properties that make it a good choice. Stud welding steel alloy is limited and often not recommended. You must try to avoid it as much as you can.
Aluminium
Aluminium is an excellent material for stud welding. It has high strength and low weight. Aluminium alloys, an alloy of aluminium with other metals, are tougher than pure aluminium and can be used to make objects that need to withstand greater forces. Alloys typically use an element such as copper, zinc, magnesium, titanium or manganese because they give aluminium different properties such as increased strength or resistance to corrosion.
Copper
Copper can be used for welding studs. It has high conductivity, which means that it doesn’t heat up in the same way as steel does when in contact with a stud welder. This material also has high corrosion resistance, which means that it doesn’t need much maintenance when used for stud welding. Copper is another material with distinct advantages and disadvantages. It can be used with brass weld studs, non-ferrous metals such as aluminium. It’s the best choice in the food industry. However, it is expensive and has a lower surface hardness than steel or stainless steel.
Brass
Brass is an affordable alternative to other base metals, such as steel or aluminium. Brass for stud welding can be used in various applications because of its ductility and resistance to corrosion. Brass is a soft metal that is easy to work with and has a low melting point. However, it is not as strong as other metal options for stud welding and should not be used for high-strength applications.
Uses of Studs
Mechanical manufacturing
●Connecting parts: Studs are a common connector in mechanical manufacturing, used to connect two or more parts together to form a whole. This connection method is stable and reliable and can withstand large loads.
Construction engineering
●Steel structure connection: In the field of construction engineering, studs are often used to connect steel structures, such as bridges, high-rise buildings and other key parts of building structures. Its high strength and stability can ensure the safety and reliability of building structures.
●Concrete roof trusses and suspension parts: For projects that require a large connection thickness, such as concrete roof trusses and monorail beam suspension parts, studs can provide effective connection solutions due to their long bolt length.
Automobile manufacturing industry
●Body parts fixing: In the automobile manufacturing industry, studs are widely used to fix body parts, such as engine hoods, doors, etc. These parts have high requirements for connection stability and reliability, and studs can meet these requirements.
Furniture manufacturing
●Fixing of furniture parts: In the process of furniture manufacturing, studs also play an important role. It is usually used to fix various parts of furniture to ensure the structural stability and safe use of furniture.
Electronic equipment
●Fixing elements: In electronic equipment, studs are also a commonly used element. For example, it can be used to fix key components such as computer motherboards to ensure the stable operation of electronic equipment.
Other fields
●Mining machinery, boiler steel structure, crane tower, etc.: These fields have high requirements for connectors and need to be able to withstand large loads and vibrations. studs have also been widely used in these fields due to their high strength and stability.
Step 1: Raw Material Inspection & Cutting of Raw Material
The raw material is picked based on the application. Like all other stud bolt manufacturers, we also choose the material to be used and conduct a chemical and physical inspection of the round bar material. The round bar raw material is then selected as per the size, followed by cutting it for the required length. This process is followed in all stud manufacturing processes.
Step 2: Hot-forging Process
The hot forging process is applied for stud manufacturing. During the forging, the bstud head is deformed by induction heating. Then, calculations are made to determine the required length, recrystallize the metal’s temperature, and bend to the required shape and size.
Step 3: Annealing
In the next step, after forging, the material is annealed for uniformity and eased for machining. All stud manufacturing include this process.
Step 4: Cleaning & Trimming
Surface finishing is the next step in the stud manufacturing process. Annealing and cleaning the nuts, bolts, and studs in a shot blasting machine makes the surface smooth and removes any scaling or burr. Next, the access material near the head is removed by trimming/drawing.
Step 5: Turning Process
The next step of stud manufacturing is the turning process. First, the material is machined to the required dimensions, usually done by a CNC machine. This process is done to remove excess material and maintain a pitch diameter.
Step 6: Thread Rolling
This is a mechanical process where threads are cold-formed and is done with two dies. One is stationary, and the other is a moving die that actually exerts pressure on the studs.
Step 7: Heat Treatment
Heat treatment is done to make the studs stronger. This process involves hardening materials in a gas carburizing furnace at a temperature of 850-900°C and then quenched in the cooling media. All the process is recorded in data loggers.
Step 8: Phosphating
Phosphating is a chemical process of treating the surface. Operations are performed to alter the surface of the stud. Soluble metal-phosphate layers are formed on the job, enhancing the function and aesthetic appeal of the product.
Step 9: Re-threading
This simple process of stud manufacturing after the completion of all the procedures.
Step 10: Packaging & Dispatch
After completing all the above steps, the products are sent for testing and inspection. First, they are thoroughly checked for their hardness levels, threading accuracy, strength, etc.; Once they pass all these procedures, protective sleeves are inserted while packing to prevent damage to the thread and the packaging.
Prep
Make sure all connecting parts are clean of any dirt. The strength and quality of a thread or done connection can be compromised by any sort of contamination.
Thread Engagement
Screw one end of the stud into the pre-threaded hole on first component. Be sure to start the stud by hand so you will not cross-thread it. Thread engagement must be min. 10mm for a M10 standard stud.
Now Mop It Down
Tighten stud with 265 ft/lb of torque and make sure it is also seated. Depending on the material and application, M10 stud torque value is usually 20-30 Nm.
Nuts Install
Put a nut on both sides of stud. The first nut against the component, then second one. Torque to 40 Nm is typical for an M10 stud using a torque wrench.
Final Inspection
Examine the assembly to make sure that both nuts are tight and the stud is centered The more out of place a bushing is, the higher likelihood that load will not be distributed uniformly and this can lead to stress failure in some cases.
Capacitor Discharge (CD) Stud Welding
Capacitors are charged to a predetermined setting on the power supply. When triggered, the stored energy is "discharged" and the burst of electricity creates the molten pool. The gun pushes the stud down into the molten pool. CD studs have a special tip on the end that is consumed during the weld.
●Application Recommendations: For non-structural applications with a rapid attachment and an undisturbed backside finish.
Drawn Arc Stud Welding
With drawn arc stud welding, the operator uses a weld tool, or gun, to place the stud against the base metal. 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.
●Application Recommendations: For structural stud welding using large-diameter studs, ferrules, and an aluminum flux.
Short Cycle Stud Welding
Similar to drawn arc stud welding, short cycle stud welding happens over a shorter time period of 20 ms to 30 ms. It is also for thin sheet metal and is used almost exclusively in industrial and automotive applications. It is typically used for small-diameter studs less than 1/2 in.
●Application Recommendations: For semi-structural applications with a rapid attachment and an undisturbed backside finish.
