Contour II

The fuel tank welder

Bio-fuels, hybrid vehicles, and organic coated material often require steel fuel tanks.

Custom-made tank fixture

Custom-made tank fixture

With seven driven axes, the innovative fuel tank fixture system as well as the wire electrode current system, welding fuel tanks with complex concave and convex three-dimensional weld seams is possible. Terne-coated steel, electro-coated Zn-Ni and galvanneal, hot-dipped tin and stainless steels can all be welded on this machine.

Benefits at a glance

  • High complex 3D tank design can be welded without any problem
  • Weld speed up to 9 m/min for steel fuel tanks
  • Integration in a fully automated production line easily possible
  • Production of various tank designs in alternative mode (fixture and program change within seconds)
  • Organic, aluminized, and galvanized coating can be processed due to patented wire profile
  • Stainless steel can be processed
  • Low energy consumption (30 kVA) due to wire electrode and PULSAR frequency converter
  • No electrode redressing necessary (constant welding condition)
  • A fuel tank fixture with its CNC program allows easy adjustment of the weld path (geometry), without the need for mechanical adjustment
  • Tank templates with direct mechanical correlations to the shape of the tank are no longer needed, it therefore eliminates costly re-work of the original template if the design should change (with some limitations)
