Beam Welding Unit
 The submerged-arc welding unit of the TE type was designed for automatic joining of sheets with a thickness between 50 and 180 mm for heavy-duty beams. For this beam welding unit an existing welding system with double-wire technology was converted to the Kjellberg tandem technology.
When designing this welding solution the focus was on quality assurance. The high degree of automation and the increased deposition rate of the tandem welding heads guarantee a better seam geometry with improved mechanical properties. The increase in performance due to a higher welding speed amounts to more than 50%.
This way, the energy input and, thus, also the workpiece distortion could be reduced to a minimum. For the customer, the entire retrofit meant more performance and higher welding quality.
