Leading Technology for the Customer’s Benefit – Laser Processing Heads for Welding and Cutting
By: Dr. Markus Kogel-Hollacher For decades Precitec has been the leading manufacturer of processing heads suitable for all laser sources including fiber lasers, disc lasers, CO2 lasers, diode lasers, Nd:YAG lasers from powers ranging from the typically used power spectrum up to 30 kW. These are directly applicable to industrial laser materials processing in order […]
High Power Direct Diode Laser Cladding of Stainless and Nickel Alloys
By: Dr. Gerald Bruck and Brandon Shinn Siemens Energy Inc. A four kilowatt high power direct diode laser is demonstrated to clad stainless (UNS S41000) and nickel based (UNS N06002) alloys. Trials are conducted using pre-placed as well as argon fed filler metal powders deposited on matching alloy substrates. Parametric tests are performed to define […]
Development of an Adaptive Control and Optimization System
By: Ehsan Fallahi Sichani A real-time, adaptive control and optimization system for laser flame cutting of thick plates of mild steel has been developed. The proposed system consists of two subsystems: a process monitoring system and a control and optimization system.
Beam Shaping Optics for Additive Laser Technologies
By: Dr. Alexander Laskin Molecular Technology (MolTech) GmbH, Berlin, Germany Homogenizing of intensity profile of laser beam brings to additive laser technologies effects that improve the performance of those technologies comparing to what can be achieved with “usual” non-uniform laser beams: the processes become more stable, less tough positioning tolerances make the technologies easier to […]
