Borusan Mannesmann has previously invested in a 1,000 kW Weldac and seam annealing system for their Houston plant which manufactures steel pipes used in oil and natural gas exploration, extraction wells and pipelines. Earlier this year, the US plant was awarded the prestigious "Tube & Pipe Producer of the Year " by the American Metal Market, for the third time in five years.
“The decision to purchase another Weldac was based on a number of important factors,” says Gemlik Automotive Factory Manager, Ihsan Özgür Turhan. “It was essential that we had high reliability and efficiency as well as the welder’s ability to continue running through any short circuit or flashover in the welding area. This was critical, as a stoppage on an SRM mill, where long length mother shells are produced, can be a very costly affair”.
Originally, Borusan Mannesmann had chosen a 600 kW Weldac for the new mill, but during the factory acceptance test visit at the EFD Induction headquarters in Norway it was decided to upgrade the welder to 750 kW. This modification was easily carried out by adding an additional inverter module and carrying out some tuning.
Since installation, the Weldac has worked flawlessly and has efficiently delivered power for all tube thickness and material combinations. The performance of the welder has enabled Borusan Mannesmann to produce very high wall thicknesses on finished small tube diameters such as Ø30x10mm. Thanks to the benefit of the patented IGBT technology that the EFD Induction welder utilises, they have reduced downtime and achieved maximum speed and thickness capacity.
