In this professional article, we present the role of 3D laser cutting and laser cutting in the modern industrial environment.
The most important things to know about 3D laser cutting at a glance
What is 3D laser cutting?
3D laser cutting is an advanced material processing technology that in which a concentrated, high-energy laser beam is used to precisely cut or shape the material. During the procedure, the Laser beam It penetrates the workpiece without contact, thus melting or evaporating the material locally, which enables extremely precise cutting operations. The term “3D” refers to the fact that this technology allows not only cutting in the plane, but also the creation of complex, three-dimensional geometric shapes, even along varying angles and curves. As a result, 3D laser cutting is a highly flexible, fast and material-efficient solution in modern industry.
Compared to traditional mechanical cutting technologies, 3D laser cutting offers greater accuracy and flexibility. Main advantages:
- High precision: Achieve accuracy down to micrometers.
- Less material loss: Thin cutting gap and minimal heat exposure reduce deformation.
- Speed and flexibility: One machine can process materials of different thicknesses and types without changing tools.
The most important applications of 3D laser cutting are in the automotive, aerospace, and electronics industries, where the fast and accurate production of complex parts is crucial.
The most important information about laser welding at a glance
What is laser welding?
Laser welding is a welding process that uses a high-energy laser beam to fuse materials together. The laser beam provides a concentrated heat source that allows for precise and fast welding with minimal heat impact on surrounding areas.
Laser welding features:
- High precision – Great for joining thin materials and small parts.
- Fast process – It can weld at high speeds, increasing production efficiency.
- Minimal heat input – Reduces deformation and changes in material structure.
- Automatability – Easy integration with industrial robots and CNC systems.
- Wide range of materials – Suitable for welding steel, aluminum, titanium, copper and other metals, as well as some plastics.
Laser welding techniques:
- Continuous Laser Welding – A continuous laser beam ensures an even seam, ideal for long welds.
- Pulsed Laser Welding – Works with short laser pulses, it is gentler and more precise, ideal for thin materials and micro-welds.
- Keyhole Welding – A high-energy laser beam creates a small-diameter, deep melting zone, resulting in a strong and deep bond.
