The pre-fabricated half-shells can be placed on the conveyor belt manually or by robot.

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.
