vertical head, needs little space and has a light structure, while the more powerful EL and HT series require more housing space and a larger support structure. The economical and compact S series has a single head and can perform simple machining operations quickly and precisely. It can machine pipes up to 2mm thick, with maximum diameter of 30mm.

Haven has demonstrated both flexibility and customer-orientated philosophy through its successful collaborations with other process equipment manufacturers. According to Dave Erickson, president of Haven, “Industry professionals think of Haven as the leading manufacturer of tube cutting equipment. We remain committed to our traditional markets, but our experience in designing and manufacturing systems for material handling appeals to manufacturers beyond our traditional market segments. Haven’s ability to adapt to a variety of industries and applications, combined with our company’s capability to design and build special one-of-a-kind machines and handling systems, gives Haven the ability to help manufacturers that might not be as familiar with our products.” Germany HKS-Prozesstechnik GmbH is a specialist in the field of welding monitoring and measuring systems, delivering improvements in weld quality. Welded tubes can pass dimensional inspection, but have incomplete fusion, which can fracture 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. 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. Fax: +1 912 264 9001 Email: info@havencut.com Website: www.havencut.com HKS-Prozesstechnik GmbH 6D26

The development of a thermo profile measuring system that can be used directly after the welding process allows in-line non-destructive testing of the welds by means of thermography. The ThermoProfileScanner is able to substitute in-line systems such as eddy current and ultrasonic. With HFI welding cold welds (cold shuts) can be recognised and prevented. For TIG/plasma applications, in-line control of penetration is possible. Unsymmetrical penetration is detected, which can be also caused by arc deviations. The optics developed for laser welding processes allow the recognition of pores and ‘out-of-positions’ of 5/100mm only from the temperature field. All systems evaluate the welding quality automatically and enable universal documentation of the temperature fields.

The MAS-1 is able to realise optimal shaped tubes from off-the-shelf production tubes. The machine has two forming tools working in opposition and translating along the main axis. The pipe is locked between two grip spindles or clamps and has the possibility of rotating around its axis, so it is machined in cold deformation. The combination of pipe rotation and forming tools translation allows many different deformations on the tube, and offers multiple machining possibilities with a variety of shapes and pitch, suitable for various sectors, from heat exchange to structural construction. The rotation of the pipe and transfer of the carriage are driven by a Fanuc- FA brushless motor, for guaranteed positioning and interpolation repeatability. The tool heads are available with pneumatic or oleo dynamics actuator and proportional control, adding power and precision to the applied tools. The machine carriage, designed and built with the same quality criteria as the bench, is available in various dimensions: the S series, with one only Iron’s Technology Srl TBC

The EL series is configurable to the user’s needs. All the accessories are designed and produced on the basis of shapes that have to be realised. This version can machine pipes up to 5mm thick, with maximum diameter of 250mm. The HT series is the most powerful, and has many customised accessories. It can machine pipes up to 10mm thick, with maximum diameter of 500mm.

The production of welded tubes has shown that the condition of the strip edge is decisive for the quality of the weld seam and the effectiveness of the welding process. Slit strip is generally the base for welding of tubes. The slit strip edge is usually irregular in regards to straightness, angle, width and structure. Coatings also affect the welding process. Mechanical edge trimming optimises the angle of the edge, and removes the burr and any cavity. This allows a superb facing to the edges for any welding process to achieve a solid and dense weld seam. At Tube 2014 in Düsseldorf Julius will present the newest version of the strip edge trimming machine. The machine treats the strip edges with six tools. It is Julius Maschinenbau GmbH 6G09
