Inner beer keg welder

The resistance welding machine for the inner beer keg

The inner beer keg welding machine complements the ANDRITZ Soutec beer keg casing welding machine.

Two deep-drawn half-shells are welded to one another with a leak-proof seam. The system can weld two sizes of inner kegs. The positioning and the welding operation are fully automated.

Benefits at a glance

  • Minimized flange width
  • Constant and leak-proof welding quality
  • Integration in a fully automated production line easily possible
  • Organic, aluminized, and galvanized coating can be processed due to patented wire profile
  • Stainless steel can be processed
  • Low energy consumption (20 kVA) due to wire electrode an PULSAR frequency converter
  • No electrode redressing necessary (constant welding condition)
  • A fixture with its CNC program allows easy adjustment of the weld path (geometry), without the need for mechanical adjustment
  • Automatic loading and unloading system
The pre-fabricated half-shells can be placed on the conveyor belt manually or by robot.
