Standing transformer welding sources with swinging arm Digital Control Unit Maximal sheet thickness 5 + 5 mm Steel, Stainless steel Aluminum alloys

Since 2011 we are proud to have robotic laser welding technology (currently 3 welding cells) at our disposal. The laser beam is generated with the solid-state laser source TruDisk with a maximal power output of 4 kW. Laser welding stands for the unrivalled welding productivity and a low heat application. This guarantees a minimal distortion and an outstanding appearance of the weld seam. The clamping fixtures for robotic welding are developed and produces in house. Very small heat affected zone resulting in the low distortion of the components Smooth and symmetrical weld seam High process stability and high welding speed Outstanding weld seam quality with a minimal or no necessity for an additional surface treatment Fixture design and development in house

The RBK 60 S is an extremely robust water-cooled weld head for a standard heat exchanger application up to an ID of 60 mm, modified to an ID of 99 mm or 120 mm. The head is pneumatically centred and is available with a rotating wire device and/ or arc voltage control (AVC) as an option. The head can also be used with a pneumatic positioner instead of a balancer. Versions: — RBK 60 S weld head with pneumatic centring, including hose package, 8m, water-cooled — RBK 60 S weld head with pneumatic centring and wire feeder incl. hose package, 8m, water-cooled — RBK 60 S weld head with pneumatic centring, wire feeder and AVC incl. hose package, 8m, water-cooled Package includes: — Weld head — Small torch incl. torch consumables and tungsten electrode Ø 2.4 mm — Water-cooled hose package, 8 m — Pull bar B — Transport case Optional: — Div. spring sleeves and pull bar sets for RBK 60 S — Torches, Balancer, Tube-to-tubesheet positioner...

The welding process is one of the core ways in which we manufacture precision tubes. Our high-quality tubing starts off as a flat strip of metal. The strip is formed into a tube through a series of rollers and the join, also called the seam, is then welded together. Welded Processes Special non-destructive testing methods – including eddy current, ultrasonic and pressure testing - are used to ensure a consistent weld. Just like with seamless manufacturing, welded tubes can be drawn down by plug drawing or sinking. This method can be used to create very long lengths of coiled tube, these can also be measured during coiling using a laser measurement. The main welded tube manufacturing processes used are strip welding and cold drawing, but other important processes in between, or at the end of the drawing process, include Please note that we have a minimum order value of £10,000.

Welded and redrawn tube manufacturing employs elements of both the welded and seamless processes. A welded and redrawn tube is welded in a conventional manner but then transferred to our seamless mill, located in the same factory. Here the product is redrawn to achieve a welded and redrawn finish. The objective of redrawing is to achieve homogenisation of the weld following annealing by cold working. This refines the structure of the weld resulting in improvements that include: Better corrosion resistance Improved fatigue life Higher mechanical integrity Please note that we have a minimum order value of £10,000.
