Abstract: A method for detecting the location of an edge, interface, seam or other structure of a workpiece uses one or two electromagnetic acoustic transducers (EMATs) to transmit an ultrasonic wave along the workpiece toward the edge and to receive a reflected wave. The velocity of the wave in the material is used in conjunction with the round trip time-of-flight (TOF) of the transmitted and reflected wave, to calculate the location of the edge. This is done by placing the transducer or transducers at known locations on the workpiece. A surface wave or 90 degree shear wave can be utilized and no contact is needed between the transducer and the surface of the workpiece. Rough and/or dirty surfaces and hostile environments can be accommodated while practicing the invention.

Abstract: A semiautomatic weld grinding apparatus for grinding the surface of a weld seam interconnecting two perpendicularly disposed tubular sections. The grinding apparatus is capable of grinding off excess weld from a saddle-type nozzle to shell weldment that follows a circular path through a plurality of planes. Alternatively, the apparatus is adaptable to function as a welding or a cutting apparatus that follows the saddle-shaped path created at the interface of two perpendicularly disposed tubular sections.

Abstract: An automated process for inspecting and controlling the quality of titanium welds using color recognition. A color sensor and white light source are mounted to a fixture. The fixture is used to traverse the weld or the part being welded is moved in the viewing path of the sensor. The sensor is calibrated to indicate the desired or undesired color of a weld. A recording device such as a computer is used to receive signals from the sensor and record the location of weld colors that indicate an unacceptable weld. Weld parameters are controlled by color feedback to minimize the deposition of unacceptable weld.
