The 12mm Shear Stud is a heavy-duty fastener used primarily in composite construction to create a strong bond between steel beams and concrete slabs. Typically made from high-strength carbon or mild steel, it features a 12mm diameter with a flat head and a plain shank, designed for through-deck welding. These studs are welded using arc or drawn arc stud welding processes and are often used in bridge decks, high-rise buildings, and industrial structures. The 12mm shear stud ensures superior load transfer, shear resistance, and structural integrity. It may come with a ceramic ferrule and is usually hot-dip galvanized or plain finish.

CD stud welding machine (short for Capacitor Discharge stud welding machine) is a specialized welding tool used to quickly and securely attach metal studs to a metal workpiece using a high-voltage electrical discharge. This type of welding is common in applications requiring precision, speed, and minimal surface marking.

🔧 How CD Stud Welding Works:

1. Capacitor Charge: The machine charges capacitors to a set voltage.

2. Stud Placement: A stud (with a special tip) is positioned against the workpiece using a welding gun.

3. Discharge: The stored energy is rapidly discharged through the tip of the stud.

4. Fusion: The arc melts the tip of the stud and the workpiece surface.

5. Plunge & Hold: The spring-loaded stud is forced into the molten pool, fusing it.

6. Cool: It solidifies almost instantly (typically <3 ms).

✅ Advantages:

• Very fast weld cycle (1–3 milliseconds).

• Minimal heat distortion.

• No backside marking (great for thin materials).

• Excellent for cosmetic or visible surfaces.

• Can weld on materials as thin as 0.5 mm.

🧰 Typical Applications:

• Sheet metal fabrication

• Electronics enclosures

• Automotive parts

• HVAC systems

• Kitchen appliances

• Signage and displays

🔧 How Stud Welding Works:

1. Positioning: A stud is placed against the base metal using a stud welding gun.

2. Arc Ignition: An electric arc is generated between the stud and the base metal, melting both surfaces.

3. Joining: The stud is then quickly pushed into the molten pool created on the base metal.

4. Cooling: The materials solidify, creating a strong metallurgical bond.
