Fiber Laser Marking is the most flexible type of direct marking available. The ability to change various laser parameters offers ultimate control, quality and speed. AMADA WELD TECH provides three different types of Fiber Laser Marking: Fiber Laser Annealing, Fiber Laser Engraving & Fiber Laser Ablation / Surface Removal.
Fiber Laser annealing creates a permanent mark that is induced by heat without removing or compromising the material. Annealing is used for all metals containing carbon which shows a color change when exposed to heat, especially stainless steel.
The annealing process offers significant advantages when marking surfaces that are already finished. The marking speed is slower compared to engraving because annealing relies solely on the thermal effects of bringing the carbon in the steel to the surface.
Fiber Laser Engraving is a technology based on the same principle, namely laser-induced ablation through melting and/or evaporation of the substrate. Engraving is a method used to create a durable, direct mark that is forgery-proof and resistant to wear and corrosion.
By laser engraving, 2D or 3D structures can be formed in injection or form molds.
This process is typically used to remove paint, coatings and other surface material to create contrast without damaging the base material. Common applications are automotive dashboards and aircraft displays where its uses include backlit buttons, anodized aluminum and painted surfaces.
