Automated Weld inspection


Working under a Technology Development program, the US Navy Joining Center (NJC) has designed and developed a prototype, portable system that can automatically inspect the contour and size of fillet welds and check for surface defects. The unit combines industrially proven laser, sensor, and optics technology with new software developed specifically for shipbuilding applications. The system is portable, durable and compact, providing an affordable, easy-to-use alternative to visual inspection that requires minimal operator training. The system measures the following weld features: leg lengths, weldface width, theoretical throat, plate angle, weld toe angles, and convexity/concavity. It also detects the following discontinuities: porosity, undercut, cracks, spatter, and slag. The system's evaluation criteria are based on military and ABS shipbuilding inspection standards.
