1. An apparatus for inspecting and analyzing welded structures comprising: a laser for directing at least one beam of light at a weld bead formed on at least two workpieces joined by said weld in a predetermined manner to define at least one visible profile line, said at least one profile line extending along at least a portion of each workpiece and along a full dimension of said weld bead; a camera directed at said weld bead for capturing an image of said at least one laser light beam forming said at least one profile line and generating a usable image signal based on said image; and a preprogrammed microprocessor assembly configured for: receiving said usable image signal and processing said signal as an image; locating at least one profile line on said image; locating said weld bead along said at least one profile line; determining a dimension of said weld bead defined along said at least one profile line; and comparing said length of said weld bead with a predetermined dimension set point to determine the quality of said weld bead.
