Xianming Laser Welding Machine Power Selection Guide
Choosing the right laser welding machine is key to achieving high-quality laser welds, efficient production, and reliable performance. At Xianming Laser, we’ve compiled a straightforward selection guide to help you match your application needs with the right laser power.
💡 Why Power Matters in Laser Welding
Laser power directly affects:
✔ Weld penetration depth
✔ Cutting speed and productivity
✔ Heat input and material distortion
Understanding your material thickness and welding goals ensures you choose the most cost-effective and capable solution.
📊 Welding Power Selection Chart
| Laser Power | Recommended Material Thickness | Typical Applications |
| 1.5 kW | 1–2 mm | Thin sheet welding (precision parts, thin panels) |
| 2 kW | 3–5 mm | Mid-thin plate welding (furniture frames, machine parts) |
| 3 kW | ≤ 8 mm | Medium thickness welding (industrial components) |
| 6 kW | 10–15 mm | Thick plate welding (heavy structure, industrial assemblies) |
💼 1.5 kW: Best for Thin Materials
✔ Ideal for welding 1–2 mm thin plates
✔ Minimal heat input and distortion
✔ Commonly used in sheet metal fabrication, home appliance parts, and precision welding applications
Benefits: Excellent control, clean welds, cost-efficient operations.
⚙️ 2 kW: Balanced Performance for Mid-Thin Plates
✔ Suitable for 3–5 mm material thickness
✔ Strong weld penetration with stable performance
✔ Great choice for furniture components, machine brackets, and structural connects
Benefits: High productivity and balanced cost and performance.
🔧 3 kW: Enhanced Power for Medium Thickness
✔ Effective up to 8 mm thick materials
✔ Capable of handling more challenging welds
✔ Ideal for industrial parts, automotive components, and aluminum or stainless steel structures
Benefits: Increased welding speed and deeper penetration.
💪 6 kW: Heavy-Duty Welding for Thick Plates
✔ Designed for 10–15 mm thick plates
✔ Excellent penetration and welding efficiency
✔ Perfect for heavy industries, large-scale assemblies, and automated production lines
Benefits: High output, powerful penetration, and best suited for high-volume/robotic weld systems.
🚀 Tips for Optimal Welding Results
🔹 Material Type Matters:
Different materials (e.g., stainless steel, carbon steel, aluminum) have varying thermal conductivities and may affect weld quality.
🔹 Welding Style & Quality:
For precision and minimal distortion on thin materials, lower power with careful parameter settings is recommended. For high-speed thick plate welding, higher power is essential.
🔹 Automation Ready:
Higher power models like 3 kW and 6 kW are ideal for integration with robotic welding cells for maximum productivity.
