The right configuration determines welding speed, stability, and return on investment.
Across more and more metal fabrication workshops, laser welding machines are rapidly replacing traditional welding processes.
Higher efficiency, lower heat distortion, and consistently high weld quality have made laser welding a key technology for industrial upgrading.
However, when it comes to purchasing a laser welder, most customers focus on one critical question:
👉 “What laser power do I really need?”
The truth is: higher power is not always better.
The right choice is the power level that accurately matches your materials and production requirements.
Laser Power Selection for Different Welding Applications
🔹 1500W | Best Value for Thin Sheet Welding
Recommended thickness: ≤ 2 mm
1500W laser welders are ideal for precision welding tasks, especially in thin metal applications. They deliver stable performance at a highly competitive cost.
Typical applications include:
✨Thin stainless steel sheets
✨Carbon steel and galvanized steel
✨Sheet metal parts, enclosures, signage letters
Best suited for:
📌Small and medium workshops
📌Users new to laser welding
👉 If your daily production mainly involves thin sheets, 1500W covers most practical needs efficiently.
🔹 2000W | The Most Versatile Mainstream Choice
Recommended thickness: 3–5 mm
2000W offers an excellent balance between penetration capability and process stability, making it one of the most widely accepted power levels in the market.
Suitable for:
✨Sheet metal structural parts
✨Medium-thickness stainless steel and carbon steel
✨Electrical cabinets, housings, welded assemblies
Key advantages:
Faster welding speed
Broad application range
One machine for multiple product types
👉 If you want maximum flexibility with minimal laser equipment changes, 2000W is a very safe and practical choice.
🔹 3000W | Productivity Booster for Higher Output
Recommended thickness: ≤ 8 mm
When material thickness increases or production volume grows, the advantages of 3000W become more apparent.
Typical scenarios include:
✨Continuous welding of medium-thick plates
✨Batch production lines
✨Applications requiring high weld consistency
Core strengths:
Deeper weld penetration
Shorter welding cycle times
Better stability in long-term operation
👉 For factories focused on output growth, 3000W strikes an ideal balance between efficiency and investment cost.
