Laser beam cutting
Laser cutting is a high-precision separation process using a focused photon beam that melts or vaporizes the material. A coaxial process gas jet expels the melt and enables fine contours with minimal heat-affected zones.
Physical-Chemical Working Mechanism
Laser beam cutting uses a high-energy photon beam that melts or vaporizes the material. The melt is then removed by a coaxial process gas jet. This process is very precise and allows cutting with minimal heat-affected zones.
Metallurgical Relevance & Welding Risks
Laser beam cutting minimizes the risk of hardness issues and cracks because it only creates a small heat-affected zone. However, incorrect gas flow or too high energy settings can lead to insufficient melting or excessive melting.
Workshop Practice & Action Guidelines
For laser beam cutting, it's important to choose the right gas flow and proper energy settings. A typical gas flow is 10-20 l/min, depending on the material. Energy settings should be adjusted to create a clear melt front without overheating the material. A precisely calibrated machine and a clean work environment are key to quality results.
