Stud Welding 101: Everything You Need to Know to Get Started With Stud Welding

Whether you're a seasoned fabricator looking to diversify your skillset or a newcomer to metalworking, stud welding is one of the most efficient and reliable fastening methods available today. In 2025, as industries continue to prioritise speed, structural integrity, and cost-effectiveness, stud welding is a process that is proving more essential than ever.

In this guide, we’ll break down everything you need to know to get started with stud welding - from how it works and what equipment you need, to choosing the right machine and materials for your application.

What Is Stud Welding?

Stud welding is a process that joins a metal stud (or fastener) to a metal base by creating a high-temperature fusion weld in milliseconds. Unlike bolting or riveting, it doesn’t require holes, back access, or secondary fixing components.

The result? A strong, permanent bond that’s both fast to achieve and clean in finish.

Types of Stud Welding

There are several stud welding methods, but the two most widely used are:

1. Capacitor Discharge (CD) Stud Welding

• Best for: Thin sheet metal, decorative or precision applications

• Materials: Mild steel, stainless steel, aluminium

• Stud size: Typically M3–M8

• Benefits: Fast (1–3 milliseconds), no surface marking, low heat input

Typical applications: Electrical panels, enclosures, HVAC, signage, automotive trim

2. Drawn Arc (DA) Stud Welding

• Best for: Structural and load-bearing applications

• Materials: Mild steel, stainless steel, other ferrous metals

• Stud size: Typically M6–M25+

• Benefits: Deeper penetration, strong welds, supports large studs

Typical applications: Construction, shipbuilding, heavy equipment, bridgework

What Equipment Do You Need?

To start stud welding, you’ll need:

Stud Welding Machine as a Power Source

The core unit of the machine stores and delivers energy to create the stud weld. Choose your suitable stud welding machine based on the welding process and stud size. Each machine requires a specific power supply to operate. Take a look at our article on stud welding power supply for more information on this.

Welding Gun

The handheld tool that positions and fires the stud onto the base material. CD and DA guns differ in mechanism and configuration. You can find lots of information about which hand tools are suitable for which stud welding machine on our website. Alternatively, our expert team is always happy to provide you with advice. 

Weld Studs

Fasteners designed specifically for stud welding are available in a variety of sizes, threads, and materials. Have a look at the range available and download our weld stud catalogues. Taylor Studwelding holds over 10 million items in stock, so we are sure to be able to supply you with the specific weld studs for your project.

Earth Clamp and Cables

These are essential components for completing the electrical circuit safely and efficiently. These accessories provide a low-resistance path for the electrical current to pass back to the power source safely, preventing electrical hazards in the welding process.

Why Choose Stud Welding Over Other Methods?

Here’s how stud welding compares to traditional fastening:

Stud welding leads in efficiency, appearance, and structural integrity.

Tips for Getting Started

• Start small: Begin with Capacitor Discharge welding on thin materials to get a feel for the process.

• Practice your technique: Consistent pressure and alignment are key for high-quality welds.

• Use quality studs: Inferior fasteners can compromise your weld integrity.

• Follow safety protocols: Always wear PPE and ensure good grounding. Ensure your technical knowledge of the process is sound before commencing work.
