Material Selection in Laser Welding: Which Material for Which Application?

Laser welding is a cutting-edge technique in industrial manufacturing. However, one of the most critical factors for optimal results is the correct choice of material. So, which materials are best suited for which applications?

1. Suitable Materials for Laser Welding

Stainless Steel: Corrosion-resistant and aesthetic. Used in automotive, medical, and food industries.
Aluminum: Lightweight and conductive. Popular in aerospace and transport sectors.
Carbon Steel: Cost-effective and durable. Ideal for construction and heavy industries.
Titanium: Biocompatible and heat-resistant. Best for aerospace and medical devices.

2. Recommendations Based on Material Thickness

Material	Recommended Thickness	Application Area
Stainless Steel	0.3 mm - 6 mm	Food machinery, medical equipment
Aluminum	0.5 mm - 4 mm	Light vehicle components
Carbon Steel	1 mm - 10 mm	Construction steel frames

3. Key Factors in Material Selection

Thermal conductivity
Expansion coefficient
Surface cleanliness
Post-welding deformation risk

Conclusion

Choosing the right material has a direct impact on the quality and durability of laser welding. A material analysis specific to your project can improve both cost-efficiency and final output.
