  • ultrasonic welding

    ultrasonic welding is an industrial technique whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld. it is commonly used for plastics and metals , and especially for joining dissimilar materials .

  • guided wave testing

    guided wave testing gwt is a non-destructive evaluation method. the method employs acoustic waves that propagate along an elongated structure while guided by its boundaries. this allows the waves to travel a long distance with little loss in energy.

  • ultrasound

    ultrasonic inspection eliminates the use of ionizing radiation, with safety and cost benefits. ultrasound can also provide additional information such as the depth of flaws in a welded joint. ultrasonic inspection has progressed from manual methods to computerized systems that automate much of the process. an ultrasonic test of a joint can .

  • cell disruption

    high pressure cell disruption. since the 1940s high pressure has been used as a method of cell disruption, most notably by the french pressure cell press, or french press for short. this method was developed by charles stacy french and utilises high pressure to force cells through a narrow orifice, causing the cells to lyse due to the shear .

  • ultrasonic testing

    ultrasonic testing ut is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. in most common ut applications, very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 mhz, and occasionally up to 50 mhz, are transmitted into materials to detect internal flaws or to characterize materials.

  • talk:ultrasonic welding

    i've got an ultrasonic press here at work that i can try and take a picture of when i get a chance. wizard191 12:40, 7 april 2010 utc after doing a little more patent digging, i found that 2891180 is a vibration mount, and is not the earliest such device. the method for ultrasonic welding seems to be first mentioned in 2,522,082 in feb 1945 .

  • ultrasonic thickness measurement

    in the field of industrial ultrasonic testing, ultrasonic thickness measurement utm is a method of performing non-destructive measurement gauging of the local thickness of a solid element typically made of metal, if using ultrasound testing for industrial purposes based on the time taken by the ultrasound wave to return to the surface. this type of measurement is typically performed with .

  • ultrasonic machining

    ultrasonic machining is precise enough to be used in the creation of microelectromechanical system components such as micro-structured glass wafers. in addition to small-scale components, ultrasonic vibration machining is used for structural components because of the required precision and surface quality provided by the method.

  • ultrasonic flow meter

    an ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and against the direction of the flow .

  • phased array ultrasonics

    phased array ultrasonics pa is an advanced method of ultrasonic testing that has applications in medical imaging and industrial nondestructive testing.common applications are to noninvasively examine the heart or to find flaws in manufactured materials such as welds.single-element non-phased array probes, known technically as monolithic probes, emit a beam in a fixed direction.
