Automated Ultrasonic Pipe Weld Inspection

testing systems for large diameter pipes with longitudinal submerged arc weld (LSAW) and one ECHOGRAPH pipe-end testing system enable the pipe mill to inspect their products with high throughput. Testing speeds for the pipe weld of up to 1 m/s are feasible due to the customer-specific Features of Multi-Electrode Submerged-Arc Welding in the Jul 31, 2013 · An increase in the thickness of the wall of large-diameter pipes is accompanied by an increase in heat input during the welding of the longitudinal weld. The increased heat input results in slower cooling of the heat-affected zone (HAZ) and diminishes the reliability of the welded joint. It was shown on production equipment at the Izhorsky Pipe Plant that the heat input during welding of the
