摘要： A system for heat treating a weld joint includes a beam generator that produces a beam directed at the weld joint. A beam splitter between the beam generator and the weld joint diverts a portion of the beam along a path. A reflector receives the diverted portion of the beam and directs it to a point at the weld joint. A modulator in the path controls passage of the diverted portion of the beam. A method for heat treating a weld joint includes directing a beam at the weld joint, diverting a portion of the beam, and reflecting the diverted portion of the beam in the direction of the weld joint. The method further includes modulating the diverted portion of the beam to control the passage of the diverted portion of the beam.

摘要： A machine includes a static member and a moving member. The moving member includes a central hub and a moving component. The moving component includes a first end portion fixedly connected to the central hub, a second end portion and an intermediate portion. The second end portion of the moving member is spaced from the static member so as to form a gap. A transmitting element is mounted to one of the static member and the moving member. The transmitting element emits an acoustic wave having a predetermined frequency across the gap. A receiving element is mounted to the other of the static member and the moving member. The receiving element receives the acoustic wave from the transmitting element. The machine further includes a controller that determines a clearance distance extending between the moving member and the static member based on the acoustic wave passing across the gap.
