For 50 years: Automatically butt-welded plating barrels

For over half a century, Richard Tscherwitschke GmbH has stood for innovation in the field of surface coating of bulk materials and has always been committed to quality and durable solutions that fulfil the high requirements.

In 1974, the company revolutionised the industry with the introduction of automatic butt welding for plating barrels. With this pioneering work, the company has set a standard in barrel production that has not only significantly improved their mechanical properties. This manufacturing method also has a positive effect on quality and process reliability for plating companies when electroplating large quantities.

Automatic butt welding (polyfusion) creates an absolutely homogeneous connection between the barrel components and thus an extremely resilient, torsion-resistant and tear-resistant barrel construction. In this process, the individual parts of the barrel are joined in such a way that there are no gaps or weaknesses at the joints. The entire barrel body is practically cast from a single mould. Even the smallest workpieces do not find any attachment points to get stuck in the corners between the end plates and the barrel body, which is a common problem with other manufacturing methods - such as plugged or manually welded barrel constructions.

A gap-free and tear-resistant barrel design is also a prerequisite for efficient drying, for example in the GALVADRY barrel dryer, or for automated loading and unloading with complete discharge, for example in the GALVAROB lid opening station. If residual bath medium from gaps or cracks gets onto the workpieces during the drying process, this inevitably leads to rejects or quality problems.

To this day, automatic butt welding is an outstanding feature of Tscherwitschke plating barrels, from which electroplating plants benefit on a daily basis.

Automatic butt welding is used to join the side parts and end walls of the Tscherwitschke plating barrel together without any gaps.

With other joining techniques, e.g. when barrel sides are plugged, gaps can occur in which small items can get caught.
