LAWI (Lawitex) – precision and durability
Laser cladding is an innovative technology used in precise regeneration and reinforcement of various types of surfaces. It consists of controlled melting of the element and additional material (in the form of wire or powder) using a laser beam. Thanks to this process, we obtain an even, durable and wear-resistant layer with minimal thermal impact on the base material.
One of the leading suppliers of laser cladding materials is the German company Lawitex, which offers the LAWI (Laser-Additive Wire) line. These wires are characterized by high technical parameters and are suitable for demanding industrial applications. Below we present the most important features and benefits of using LAWI wires in laser cladding processes.
The most important features of LAWI wires
- High purity and controlled chemical composition
- Developed according to strict standards, which minimizes the risk of porosity or inclusions in the overlay layer.
- Depending on the needs, it is possible to select wires based on various alloys (iron, nickel or cobalt) adapted to specific properties (resistance to abrasion, corrosion, high temperature).
- Various diameters and shapes
- Based on the manufacturer’s information (see Lawitex – LAWI), the wires come in several thickness variants, the most popular being 0.3-0.6 mm.
- This allows for optimal matching of the material to the type of detail and the power of the laser used (CO₂, Nd:YAG, fiber).
- Precise melting and uniform casting
- Thanks to the precise shape and stable parameters of LAWI wire feeding, the welded layer is exceptionally even and uniform.
- The process is carried out with a lower risk of defects, which shortens the time of any finishing processing.
- Compatibility with various laser systems
- LAWI wires can be used in most commonly used laser cladding installations, eliminating the need for expensive equipment modifications.
- Lawitex also supports parameter configuration to fully optimize the cladding process.

Frequently Asked Questions (FAQ)
- What wire diameter should I choose?
- It depends mainly on the laser power, the type of detail and the intended thickness of the weld. The most popular diameters are in the range of 0.3–0.6 mm, which is confirmed by the information on Lawitex – LAWI. In case of doubt, we will advise you on the optimal variant for your needs.
- Are LAWI wires compatible with my laser?
- These wires are designed to work with most industrial lasers (CO₂, Nd:YAG, fiber). If you have a specific device model, contact us – we will verify the parameters.
- Is it possible to regenerate cutting tools?
- Yes, laser cladding allows for precise and quick reconstruction of cutting edges. Examples of applications in this field can be found in the materials of the manufacturer Lawitex.
- What are the main benefits of laser cladding compared to traditional methods?
- Laser cladding allows for precise control of the heat-affected zone, limiting deformation of the detail. The process is fast, economical (less additional material) and gives high durability of the weld deposit.
Well-selected LAWI (Lawitex) wires for laser cladding are a guarantee of maximum precision, resistance and an efficient process in many industrial applications – from injection molds in the tool industry, through engine components in the automotive industry, to strategic components in the aviation and energy sectors.
