Rofin-Sinar Inc.The Rofin Laser Macro Group has announced the DC 045W, a CO2 slab laser with an average output of 4500 W. This diffusion-cooled laser has a beam quality of K ≥ 0.9, which enables narrow and deep welding seams with minimum heat distortion. It requires no gas circulation, and its single transmitting lens is a diamond window. The device can be used in large-capacity remote welding systems for the production of automotive subassemblies and for welding aluminum components, gearbox and engine parts, tailored blanks, pipes and extrusions.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 7/20/20223D PrinterThe Sapphire XC 1MZ 3D printer from Velo3D Inc. allows users to print parts with a height of 1 m, increasing the addressable use cases of end-to-end metal additive manufacturing.
