Step 1: Safety Checklist Before Using a Laser Welder
Laser Welding Safety Checklist
✔ Check power cable condition
✔ Inspect laser lens for damage
✔ Ensure proper grounding
✔ Verify coolant level
Required PPE
Laser safety goggles (wavelength-specific)
Fire-resistant clothing
Insulated gloves
Important: Always operate in a well-ventilated workspace to avoid exposure to metal fumes.

Step 2: Handheld Laser Welding Settings (Beginner Friendly)
Golden Rule
Power → Speed → Focus
Recommended Settings for Stainless Steel (0.8mm)
| Parameter | Value |
|---|---|
| Power | 800W |
| Speed | 15 mm/s |
| Focus | Surface |
How to Adjust Parameters
Too much burn-through? Reduce power
Weak weld? Slow down the speed
Unstable seam? Adjust focus
---
Step 3: Laser Welding Techniques for Beginners
Angle: 70°–75°
Distance: 1–2 mm
Movement: Smooth and steady
🎯 Pro Tip: A stable hand is more important than high power for clean welds.

Common Laser Welding Problems and Fixes
Pores in Weld
Cause: Excessive power → Solution: Lower power
Weak Penetration
Cause: Fast speed → Solution: Slow down
Spatter
Cause: Incorrect angle → Solution: Maintain 75°
Overheating
Stop the machine every 30 minutes to cool down.
