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 […]
Internal Bore Laser Cladding
By: Paul Colby Background Bimetallic cylinders are pressure vessels functioning as a component in a system to melt plastics with abrasive additives such as glass and minerals. These vessels have been manufactured the same way since the 1950‘s. Xaloy has developed and patented a new technology that will improve the useful life of bimetallic cylinders […]
