ERW pipes inspection system – weld Ultrasonic Testing machine

The ERW pipes inspection system (FLAW HUNTER EP 9501) is an online machine for weld ultrasonic testing of ERW (electric resistance welded) pipes and square profiles. It is designed to identify longitudinal faults in the heat-affected zone (HAZ) of fusion welds. International standards of erw pipe and profile manufacturers state that an online erw weld ultrasonic testing machine is an essential and integral component of the manufacturing process. In order to test these pipes using the ultrasonic method, a unique mechanical system that can hold, move, and position at least four probes independently is required.

ERW pipes inspection system overview

At least four probes can be held, moved, and adjusted independently using the special mechanical ERW pipes inspection system. In order to detect longitudinal flaws in accordance with standards, the probes’ waves must propagate in a vertical position, which is why they are positioned next to the weld. FLAW HUNTER EP 9501 can be placed in a manufacturing line directly after the welding machine and utilize the water in the line for testing and cooling.2

The four distinct angle probes and channels in the ERW pipe ultrasonic inspection system are held in unique holders and arranged in pairs in front of each other using the water gap technique. In order to find longitudinal root defects in the weld, one pair is employed to detect longitudinal surface defects.3

The software of ERW weld ultrasonic testing machine

The erw pipe testing machine’s software is able to evaluate the position and depth of the fault and saves all test results in distinct strip charts. When a defect occurs, the paint spray automatically labels the affected area and the alarms sound.4

Because of its high PRF and powerful software filtering, the erw pipe weld ultrasonic testing system can test at a high speed of 60 meters per minute. This allows it to filter out electronic noises generated by the high frequency voltage of the welder machine, annealer, and surrounding electromotors.5
