New plant for taphole welding

As part of the project to qualify TIG taphole welding, a new system for TIG taphole welding was put into operation at ifw Jena.

The specialized InFocus system from Kjellberg, which ifw Jena developed together with OSCAR PLT, combines a 1000 A-DC welding current source with a hot wire feeder. In addition, the filler material can also be supplied oscillating.

The InFocus process is suitable for single-layer welding of steels with up to 10 mm, e.g. for full connections or also root, filling and cover layers of thicker sheets as longitudinal and circumferential seams. The new system technology will be used at ifw Jena to investigate TIG taphole welding of steels in future.

As part of the BMWi-funded project "Qualification of TIG taphole welding", the welding of structural steels with sheet thicknesses of up to 8 mm is being investigated without costly seam preparation. The aim is to increase process stability and productivity when welding structural steels.
