GE Inspection Technologies Ultrasonics Krautkramer Testing Machines Strip Testing Testing parent material of welded pipes We supply the machine for testing to specifications. Parent material testing is divided into center zone and strip edge. The strip can be tested either before or after forming. Our machines either make fixed track testing of the strip width or strip edges and the remaining strip in oscillating tracks (min. 1 probe monitors the edge and the others the center zone). Probe type and numbers, working with water gap or water delay, are made to meet specifications and sizes. A pulse reflection mode is used. Track width is probe dependent. The backwall echo monitors function and coupling. Many factors govern the number of probes: • Test track width (especially important for the strip edge) • Test specifications (e.g. flaw size to be detected) OSC. 1 2 n Oscillating strip testing (OPR) 1-n 2-n 1-n 1-n 1-n BPE only fixed tracks BPO fixed oscillating tracks Direction of oscillation OBPE fixed tracks and oscillation “comb” 2-n 1-n 1-n fixed probe oscillating Testing direction/ Feed direction 2-n 2-n
