Patent Number Title Of Patent Date Issued
5477025 Laser nozzle December 19, 1995
A nozzle for delivering particulate matter into a molten pool created on a substrate includes a core through which the particulate is delivered, an annulus surrounding the core for simultaneously delivering a shield gas toward the molten pool and shield gas conditioning apparatus. The
5453329 Method for laser cladding thermally insulated abrasive particles to a substrate, and clad substr September 26, 1995
A method of applying abrasive materials to a substrate includes the steps of forming a relatively small pool of superheated molten metal at the surface of the metal substrate by creating an interaction area on the substrate with a localized high energy source. A powder system is injected
4804815 Process for welding nickel-based superalloys February 14, 1989
A process for preventing crack formation in nickel alloy substrates having a gamma-prime phase includes providing a substrate comprised of a nickel alloy having a gamma-prime phase. A portion of the substrate is irradiated with a laser beam and thereby forms a molten pool of the alloy. A
4803335 Gas shroud and method February 7, 1989
A gas shroud comprises a chamber having a beam inlet, a gas inlet and an outlet portion. A shroud having an inner surface and an outer surface is operably associated with the outlet portion and is rotatable relative to the chamber. A drive system is operably connected to the shroud for
4777341 Back reflection monitor and method October 11, 1988
A beam monitor comprises a mirror for reflecting an incident beam of radiation to a target and for receiving a reflected beam from the target and has a surface on which the beams impinge. Incident and reflected beam channels are orthogonally disposed within the mirror. Each of the channe
4726715 Screw powder feeders February 23, 1988
A screw powder feeder has a rotary screw (12) disposed at the base of a hopper (10). The screw (12) comprises a twist drill bit. Powder is discharged into a chamber (18) and picked-up by a flow of gas. The pressure in chamber (18) is varied relative to the pressure in hopper (10) to
4724299 Laser spray nozzle and method February 9, 1988
A laser spray nozzle assembly includes a nozzle body with first and second spaced apart end portions. A beam passageway extends between the end portions and permits a laser beam to pass therethrough. A housing surrounds the second end portion. The housing is spaced from the second en
4704030 Electromagnetic radiation detectors November 3, 1987
A predetermined characteristic of a laser beam is detected by disposing a reflector (11) in the path of the beam and coupling an electromechanical transducer (12) to the reflector to detect a mechanical response of the reflector to the incident beam.
