Drawing:
940nm Diode lasers are the ideal tool for all types of deposition welding. The essential 940nm diode laser advantages include high flexibility, short processing times, minimal deformation of the treated workpieces and fine, highly adherent coatings. The extremely wear-resistant surfaces require almost no reworking. There are many reasons for additional coating. Whether it is protecting highly stressed surfaces of metal workpieces from wear and corrosion or repairing high-quality components, coating can be carried out effectively with the laser, as can the generative production of complex structures.
Laser cutting removes material by expelling vaporized material to ensure precision and prevent disruptions. This is achieved with focused gas jets and short laser pulses, avoiding buildup that causes local heating and thermal lensing.
Laser welding, on the other hand, melts material instead of removing it. It uses lower-intensity long-pulse lasers and defocused shielding gas to prevent oxidation.
For high-power laser applications, off-axis parabolic mirror systems are preferred due to their durability and replaceable sapphire windows that protect internal optics.
