Thermal field seam evaluation TUBES that seem to be completely physically correct can fracture in use. The reason for this, especially in ERW welding processes, is too low or too high heat input or material faults. Commonly used eddy current or ultrasonic systems are limited in detection of such errors. Operation next to the welding spot is possible through a glassless, gas purged and water cooled construction. From the recorded thermal data the welded seam’s basic parameters are calculated. The threshold is freely adjustably and therefore adaptable to the respective process. The basic parameters like seam position, width, symmetry and temperature are the base to recognise such weld defects as lack of fusion, cold welds, pores or seam offset. up to 180m/min. As a result, irregularities can be recognised of dimension less than 1mm in the thermal signature. The sensitivity of the TPS allows it to measure a temperature range from approximately 650 to 1,350°C. For weld inspection purposes, the characteristic of the heat-affected zone (HAZ) depends directly on the weld seam quality. Therefore unacceptable seam irregularities and weld defects will be detected, marked and sorted out.

Even penetration faults or seam asymmetry can be recognised in the running production, and every inch of the tube is controlled and documented. The ThermoProfileScanner (TPS) from HKS-Prozesstechnik makes this possible. The TPS measures the infrared intensity of radiation of the cross-section of the welded seam during solidification with a frequency of 100 to 400Hz. This allows welding speeds of

Eddy current probe INNOSPECTION Ltd has introduced a novel approach to the inspection of swaged carbon steel boiler tubes with the development of a specialised rotational Eddy Current probe. The swaged carbon steel boiler tubes are inspected for internal longitudinal cracking. This form of crack occurs on the internal surfaces of the pull-bent sections of the tubes, propagating directly from the adjacent external tube joining seam (vein) welds. The Innospection probe is collapsible in Email: info@innospection.com Website: www.innospection.com

order to overcome the restricted tube bore entry formed by a tube-sheet swaged joint. The probe eddy current sensors remain collapsed going through the swage. Once inside, the eddy current sensors are rotated by an electrical motor and are forced outwards by the centrifugal force. Innospection Ltd – UK
