Continually seeking to increase welding speeds while simultaneously improving weld quality assurance, CRC-Evans developed narrow gap welding technology that can deposit fill and cap passes at travel speeds in excess of 1m/min. However, such high welding speeds threaten the limits of conventional through-arc seam tracking. The company also identified that the overall pipe joining process could be dramatically improved if additional information about weld preps and joints could be obtained before, during and after welding.
