Laserauftragsschweißung

Laserauftragsschweißen, often abbreviated as LAS, is a metal additive manufacturing process that utilizes a laser beam to melt and fuse material, typically in powder or wire form, onto a substrate. This process allows for the precise deposition of material layer by layer, enabling the creation or repair of complex geometries.

The core principle involves a laser beam scanning a designated path on the workpiece. Simultaneously, filler material is fed into the melt pool created by the laser. This filler material can be in the form of fine powder or wire, depending on the specific application and equipment used. As the laser moves, it melts both the filler material and a small portion of the substrate, creating a metallurgical bond. Subsequent layers are then deposited on top of previous ones, building up the desired structure.

LAS is known for its high accuracy and ability to create intricate parts with fine features. It offers excellent control over the deposition process, leading to dense and well-bonded layers with minimal porosity. The process is versatile and can be applied to a wide range of metals and alloys, including steels, aluminum alloys, nickel alloys, and titanium.

Applications for Laserauftragsschweißen are diverse and include the repair of worn or damaged components, the addition of functional features to existing parts, and the fabrication of entirely new components. It is particularly valuable in industries such as aerospace, automotive, tool and die manufacturing, and medical device production, where high precision and material performance are critical.
