LASER CLADDING

Laser cladding is a process that involves using laser beam to generate heat. In practice, this means applying an additional layer of material onto the surface of the workpiece and simultaneously melting it. This can be achieved using metal powder or welding wire, for example.
When using metal powder for laser cladding, the laser focuses its energy on a specific area of the workpiece, causing localized heating and melting of the surface. At the same time, metal powder is delivered to the laser’s focal point in a gas shield. As the laser heats the surface, the metal powder also melts, creating a strong bond with the workpiece surface. This process results in a durable and homogeneous surface after excess material is removed.

Material clad with laser forms a cohesive and robust bond, which in most cases leaves no traces after processing, making the mold or tool comparable to new. Depending on the welding wire used for laser cladding, the clad areas can be reprocessed, polished, or subjected to photochemical etching.

LASER WELDING

Laser welding is an advanced method of joining materials that utilizes a concentrated beam of laser light. Due to its high precision, this process is widely used across various industries.
Laser welding involves melting welding wire by directing a highly concentrated beam of light with very high power density to the welding location. The process typically utilizes a laser beam with a wavelength of 1067 nm generated in a synthetic neodymium-doped yttrium aluminum garnet crystal (Nd:YAG). This method is particularly effective for welding small, delicate components that are sensitive to deformation from overheating. Laser welding also minimizes the risk of weld sinks and distortions.

The unmatched precision compared to other welding methods, the ability to create very thin weld seams, and the minimal thermal impact significantly reduce both the time and costs of subsequent post-processing.

LASER WELDING

Proces spawania laserowego to zaawansowana metoda spajania materiałów, która wykorzystuje skoncentrowaną wiązkę światła laserowego. Dzięki wysokiej precyzji, proces ten jest szeroko stosowany w różnych gałęziach przemysłu. Energia niezbędna do spawania jest generowana przez laser.
W laserowych systemach spawalniczych, intensywna wiązka laserowa jest przeważnie kierowana na spawany obszar za pomocą elastycznych światłowodów. W tym miejscu, dzięki zastosowaniu zaawansowanego układu optycznego energia lasera jest skupiana w niewielkim punkcie. co prowadzi do lokalnego podgrzewania i topienia materiału obrabianego, umożliwiając skuteczne łączenie ze sobą spajanych elementów.

TIG WELDING

TIG welding technique (Tungsten Inert Gas) utilizes a non-consumable tungsten electrode and a neutral gas shield. Heat required for welding is generated by an electric arc between the electrode and the material. The process is predominantly manual, though automated versions exist.

TIG welding is widely acclaimed for its speed, versatility, and intuitive application. This method is suitable for welding high-quality alloys such as aluminum, stainless steel, acid-resistant steel, and titanium alloys. A distinctive feature is that after welding, there is no need for extensive mechanical post-processing. Another advantage of this method is the ability to weld very thin sheets, even as thin as 0.5 mm, with precise control over the welding process.

Laser Welding vs TIG Welding

The choice between TIG welding and laser welding largely depends on the application’s requirements.

Laser welding is preferred when the highest precision, speed of process, and minimal heat-affected zone are priorities. Laser technology excels especially in hard-to-reach areas and provides significantly higher homogeneity in welded joints.

TIG welding is more versatile and suitable for a wide range of applications, especially where materials are thicker and precise process control is crucial. It’s also worth noting that the initial investment costs, including the purchase of the welding equipment, are significantly lower compared to laser systems.

Undoubtedly, laser welding and cladding represent more advanced processes, but it’s essential to tailor the technique to the specific application requirements.
