Laser Cutting of Mild Steel
Complex, Multi-Dimensional Cutting Made Easy
The cutting in two dimensions is a domain of the CO2 laser. Typical cutting speeds for mild steel are for example at 18m/min for 1 mm, 4.5 m/min for 3 mm and 1.5 m/min for 8 mm material strength. Basically, the cutting of metals with lasers happens through the local heating of the material above its melting point in the focal point of the focused laser. The resulting molten material is ejected by a gas flow oriented coaxially to the laser beam so that a kerf is formed.
For low-alloyed steels in particular, oxygen is typically used as cutting gas. At the moment the maximal processable counter thickness for laser flame cutting of steel is approximately at 25 mm.
2D Laser Cutting of Mild Steel
- Mild steel is the most frequently cut material in the industry. Thus e.g. gears, blinds, coverings or chain links of mild steel are cut using lasers.
3D Laser Cutting of Mild Steel
- In combination with fiber optic (solid-state laser) or mirror systems (CO2 lasers) also complex, three-dimensional mild steel components can be cut such as hydroformed parts for the automotive industry.
