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.
