Mill installations with speeds up to 250fpm are best suited for this new product. The company states that HavenTrak minimises cost by providing an accurate and distortion free cut that eliminates the need for secondary operations. The system is simple to operate, easy to maintain, and built for longevity. The HavenTrak flying shear tube cutting machine is also claimed to have the highest return on investment of any competitive system. Havenwill also feature video presentations of its entire product line, including HavenTrak flying shear cut-off, Dual-Blade Shear cut- off, Kleencut ® supported shear cut-off, double end finishing, wire brush de-burring, measuring/inspection, and packaging/ stacking equipment.

affected zone (HAZ) depends directly on the weld seam quality. Errors are detected, and tubes lengths are marked and sorted for secondary inspection. 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 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 approx. 650°C to about 1,350°C.

For more than 15 years it has provided mass heating equipment and systems with a high level of technology and

and measuring systems delivering improvements in weld quality. Welded tubes can pass dimensional inspection, but have incomplete fusion which fractures under stress when put to use. In ERW/HFI welding, a main cause is too low or too high heat input or input material non conformance. Eddy current or ultrasonic systems are limited in the detection of such errors. Analysing the weld seam and quality via the thermal properties creates new detection possibilities such as penetration faults or the weld seam heat distribution can be recognised during production. Complete tube length data is documented and archived for traceability. The ThermoProfileScanner of HKS-Prozesstechnik GmbH from Germany is proven in the field to deliver results. Using control limits, these values are freely adjustably and therefore adaptable to the client process, material and mill. The basic parameters like seam position, width, symmetry and temperature form the basis to recognise weld defects such as lack of fusion and cold welds. For weld inspection purposes, the characteristic of the heat-
