A method of repairing a blisk having a hub with circumferentially spaced blades. The method can include removing a portion of a blade and replacing the portion with a replacement piece. The method can further include welding the replacement portion to the blade. The method can further include at least one of inspecting the weld after the completion of the weld and prior to heat treatment, dimensionally inspecting the replacement piece after machining, peening the blade, and surface finishing the replacement piece.

The disclosure is a method and system for monitoring the condition of an optical protective component in a laser system associated with a data processor. In one embodiment, the method begins with directing light from the process head of a laser through the optical protective component onto a workpiece. A return light via the workpiece causes light signals coupled through the protective component and into to a fiber which extends proximate the protective component and thereafter flexibly to a sensor. The sensed signals allow monitoring the condition of the protective component during use. The method and system is operative for use with optical protective elements downstream of the process head.

An etching method using a bevel etching apparatus is provided. The bevel etching apparatus is configured to etch a substrate by emitting a laser beam and includes a laser generator and a power meter configured to measure the laser beam output from the laser generator. In the method, the power meter is irradiated with the laser beam for a predetermined period of time before etching the substrate by irradiating the substrate with the laser beam. An output value of the laser beam is measured by the power meter. It is determined whether the measured output value of the laser beam is in a range of predetermined thresholds with respect to an output setting value of the laser beam output from the laser generator.

A turbine housing assembly is disclosed, the assembly including a turbine housing defining a rotational axis for a turbine wheel. The assembly further includes a cartridge that is receivable by the turbine housing, the cartridge including spacer posts and a plate component that includes spacer post openings. The spacer posts may be laser beam welded into the spacer post openings to form laser beam welds as well as define an axial vane clearance between the plate component and a surface of the turbine housing. The turbine housing is further contacted by ends of the spacer posts. Each of the laser beam welds includes a power ramp-up area, an intermediate area and a power ramp-down area, where the power ramp-down area curves away from the power ramp-up area to reduce weld defects.
