 2. Working Principle of Stud Welding

Stud welding is a process where an electric arc is generated between the stud and the base material, rapidly melting both surfaces. Pressure is then applied to complete the weld within milliseconds.

Core Advantages

• Extremely fast welding cycle (1–100 ms)

• High joint strength and reliability

• Simplified process with lower labor cost

• Suitable for automation and mass production

The projection weld stud design further enhances this process by:

• Localizing heat at projection points

• Improving weld consistency

• Reducing thermal deformation

 3. Core Process Optimization for Projection Weld Studs

3.1 Standard Welding Parameters

For optimal welding performance:

• Welding Current:
       Stud diameter × (100–110 A)

• Welding Time:
       Stud diameter × (3–5 ms)

These baseline values should be adjusted based on:

• Material type

• Plate thickness

• Surface condition

 3.2 Welding Gun Parameter Control (Critical Factor)

Over 80% of welding failures are caused by improper welding gun settings.

Key parameters include:

• Spring pressure adjustment

• Lift distance control

• Torch alignment

Incorrect settings can result in:

• Weak welds

• Excessive molten pools

• Stud misalignment

 3.3 Voltage & Equipment Matching

Incorrect voltage settings may cause:

• Incomplete fusion

• Overheating

• Poor weld appearance

Solution: Fine-tune voltage parameters based on actual welding results.

 4. Common Welding Defects & Practical Solutions

4.1 Excessive Weld Pool

Causes:

• Excessive current or voltage

• Incorrect lift or pressure settings

Solutions:

• Reduce energy input

• Optimize welding gun parameters

• Ensure proper equipment condition

 4.2 Uneven Weld Pool (Magnetic Blow)

Causes:

• Poor grounding

• Torch not perpendicular

Solutions:

• Correct grounding clamp placement

• Maintain vertical welding angle

 4.3 Excessive Spatter

Common in: Aluminum welding

Solutions:

• Pre-wet surface or apply light oil

• Optimize welding parameters

 4.4 Backside Deformation (Back Mark)

Main Causes:

• Excessive welding current

• Thin sheet material (<1 mm)

• Incorrect torch pressure

Engineering Solutions:

• Reduce welding energy

• Optimize torch parameters

• Use high-quality welding equipment

• Increase plate thickness (≥2 mm if possible)

 5. Material Compatibility & Application Guidelines

5.1 Thin Sheet Metal Welding

• Thickness: 0.5–3 mm

• Recommended process: Capacitor discharge welding

• Ideal for M3–M10 projection weld studs

 5.2 Cold-Rolled Steel

• Smooth surface, excellent weldability

• Best choice for precision welding applications

 5.3 Hot-Rolled Steel

• Presence of oxide scale

• Requires:

• Higher energy input

• Longer welding time (5–100 ms)

• Recommended process: Short-cycle arc welding

 5.4 Coated Materials

Insulating Coatings

• Poor conductivity

• Requires surface grinding before welding

• Increase welding energy if necessary

Conductive Coatings

• Easier welding

• May cause slight spatter
