W elding E quipment Orbital welding carriage increases production

Gullco International Limited – Canada Fax: +1 905 953 4138

GULLCO’s Pipe Kat ® automated pipe welding system with integrated wire feeder unit incorporates 40 IPM welding carriage design with quick action mounting for ease of installation. The carriage is equipped with a high speed return feature for faster repositioning of the carriage. The Pipe Kat is also equipped with a linear oscillator with adjustable weave width and weld joint centreline adjustment, and all electronic motorised functions incorporate jog settings. The system includes a main control box with 7,620mm (25ft) umbilical, wire feed spool capacity of 4.5kg (10lb), maximum

wire speed of 89 to 226cm/min (35 to 633 IPM), and a wire size range of 0.8 to 2mm. The welding torch uses standard consumables.

Titanium tube mills THERE is a very strong trend for production of seam welded titanium tubes in the tube market. Titanium tubes are used in airline engines or frames, chemical and nuclear power plants as they are very high in corrosion resistance, light in weight and high in strength. For each nuclear power plant a volume of 300 tons of titanium tube is required. So there is a lack of titanium tube production capacity at the moment. The raw material costs of titanium are 10 to 20 times higher than comparable steels. State-of-the-art is that stainless tube mills are not able to combine highest tube quality levels, production reliability and sufficient production speeds at lowest scrap rates for titanium tube manufacturing. To follow this Rosendahl has developed the new Titanium Tube Mill Series TH-G Ti. These mills are designed for the production of tubes for high security relevant issues like heat exchanger products for power generation. The main process steps are fully reengineered according to titanium alloys properties and end user requirements: • Tube forming and calibration to handle high spring back and secure smooth surface

• Welding and heat treating processes which can avoid restrictively absorption of atmospheric gases which would lead to material embrittlement and corrosion. The dimension range for the TH-G Ti Series goes up to 120mm in diameter and can cover wall thickness values between 0.2 and 3mm. The unique features of the TH-G Ti Series are: Rosendahl Hybrid-Forming for titanium tube production combines the advantages of moveable and non-moveable tooling; introduction of high performance level to the titanium tube manufacturing by use of high-end TIG-plasma- or laser welding technology; fully integrated quality control system including continuous thermographical analysis of the welding seam; STOP and GO production for zero defect welding for minimisation of scrap rates; and Rosendahl titanium tube mills are equipped with in-line annealing systems which can also handle the speed range achievable with Laser Welding Systems.
