A handheld fiber laser marking machine is a portable and versatile tool used for engraving, etching, or marking various materials, including steel. Fiber lasers are particularly effective for marking metals due to their high precision, speed, and durability.
Key Features of Handheld Fiber Laser Marking Machines for Steel:
Laser Type:
Typically uses a fiber laser source (20W, 30W, or 50W common for handheld models).
Wavelength: 1064 nm (ideal for metals).
Marking Capabilities on Steel:
Engraving: Permanent marks (deep or surface-level).
Annealing Marks: Dark/black marks without material removal (common for stainless steel).
Etching: High-contrast markings for logos, serial numbers, barcodes, etc.
Advantages for Steel Marking:
High Precision: Fine details, small text (0.1mm or smaller).
No Consumables: Unlike ink-based methods, no need for inks or chemicals.
Durability: Resistant to wear, heat, and corrosion.
Speed: Faster than mechanical engraving.
Portability & Ease of Use:
Lightweight design for on-site marking.
Adjustable focus for different material thicknesses.
Touchscreen or smartphone app control in some models.
Applications in Steel Industry:
Part Identification: Serial numbers, QR codes, barcodes.
Branding: Logos, company names.
Tool & Machinery Marking: Asset tracking.
Aerospace & Automotive: Component traceability.
Considerations When Using on Steel:
Surface Finish: Works best on clean, polished, or coated steel.
Power Settings: Adjust based on steel type (stainless, carbon steel, etc.).
Safety: Wear protective eyewear (laser safety glasses).
