Weld studs, sometimes known as weld on threaded studs, are specialist assembly hardware designed to be permanently attached to a metal workpiece through welding. Unlike standard screws or bolts, they do not require a pre-drilled or tapped hole for installation.
Instead, they feature a precision-engineered tip that facilitates either capacitor discharge or drawn arc welding, fusing the weld stud directly onto the surface of the base material. This process creates an incredibly strong and durable fixing point, available as an externally threaded weld stud (male), an internal threaded bore (female) or an unthreaded pin.
How Weld Studs Work
The core function of a weld stud is to add a reliable attachment point to a metal component, such as sheet metal, with minimal modification and maximum strength. The installation process is exceptionally fast: the stud is placed in a specialised stud welding gun, pressed against the workpiece and once a circuit is complete, a controlled electric arc melts the stud tip and a small area of the base material. In milliseconds, the two components are fused, forming a permanent, high-strength bond.
This stud welding process of installation is highly valued in modern manufacturing. For instance, in machinery enclosures, welding studs to sheet metal housings allows engineers to mount additional components, earth connectors and cover panels without compromising the enclosure's integrity or IP rating, as no holes are drilled into the workpiece.
Materials Weld on Threaded Studs Are Made From
Choosing the correct material weld on threaded stud is critical for ensuring a compatible and durable weld. Accu's range is precision-engineered from high-quality materials to meet your application's demands:
- Stainless Steel - (A2): Offers excellent corrosion resistance and robust strength, making stainless steel weld studs a reliable choice for general-purpose applications, machinery and food-grade equipment. Available in untreated or with a matte black AccuBlack finish for low reflectivity.
- Aluminium: This lightweight option provides superb corrosion resistance and is the ideal choice when working with aluminium base materials. Using an aluminium weld stud on an aluminium panel prevents galvanic corrosion and ensures a perfect, homogenous bond.
- Steel: Grants a combination of strength, durability and resistance to corrosion. Finished with a copper plating for additional conductivity and corrosion resistance for demanding electrical applications.
Sizes and Types of Weld Studs Available
To support projects from prototyping to large-scale production, we offer a wide range of weld stud types. Our selection includes externally threaded weld studs (male) and internally threaded studs (female) for secure component mounting, as well as unthreaded studs that are perfect for use as locating pins, pivots or supports.
These studs are available in metric thread sizes from M3 (3mm) up to M10 (10mm) and in lengths ranging from 6mm to 60mm. All our weld studs are manufactured to the ISO 13918 standard, guaranteeing precision, reliability and consistency for your engineering projects.
FAQs
Q: What is the main advantage of using a weld stud?
A: The main advantage is the ability to create a strong, permanent attachment point on a metal surface without drilling or tapping. This process is extremely fast, maintains the full structural integrity of the base material, and leaves the reverse side of the workpiece clean and unmarked.
Q: Can you weld studs to thin sheet metal?
A: Yes, welding studs to sheet metal is a very common and effective application. Capacitor discharge welding is specifically designed for thin-gauge materials, as its rapid weld time fuses the stud without warping or burning through the panel or parent material.
Q: Do I need a special tool to install weld studs?
A: Yes, weld studs are installed using specialised equipment and techniques such as a drawn arc stud welding or capacitor discharge stud welding. This tool precisely controls the electrical arc needed to melt and fuse the stud to the base metal, ensuring a consistent and reliable connection.
Q: Why are there different materials like stainless steel and aluminium?
A: The stud material must be compatible with the base metal it is being welded to. Using an aluminium weld stud on an aluminium panel, or a stainless steel weld stud on a stainless component, is essential for creating a strong metallurgical bond and, crucially, for preventing galvanic corrosion.
