Hall A3, Booth 306

Raylase will present its latest products and solutions that can be implemented, for example, in the solar industry, additive manufacturing or the e-mobility market. The firm is also celebrating its 20th anniversary this year. 

One of the highlights of the exhibit will be the firm’s High Power Welding Module that offers wavelengths between 420-480nm. In the e-mobility market, two dissimilar materials are used for through-plate connection of the cell connectors of the battery pouch cells in lithium batteries. Welding ensures that both a robust mechanical connection and a very good electrical connection are created. 

The absorption of the copper contact strips is significantly higher for the 420-480nm wavelength range than for the infrared wavelengths, which means that the energy can be delivered into the material using just a fraction of the laser power. This results in a homogeneous weld bead that penetrates the copper and bonds the aluminium – significantly improving the quality of the entire welding process. 

Another highlight will be the deflection units Axialscan Fiber-20 for additive manufacturing applications and the Axialscan Fiber-30 for additive manufacturing and welding applications in the e-mobility market. These deflection units are being unveiled at the show and are designed to boost the productivity of AM powder bed machines and systems for welding batteries and fuel cells. The units are optimised for easy integration and reliable operation, in particular in powder bed machines. Process monitoring is also integrated, so that the quality of the AM process can be checked at any time.
