Manufacturing heavy duty drums requires the highest levels of precision in design and production. In particular the welding of the 30-70mm strong metal sheet covering presents extreme challenges. Welding is mostly carried out on specialised submerged arc welding machines. The RWE Maintenance & Engineering Center has developed specialised processes for finishing the root run and the heat treatment that is required subsequent to the welding process.

Machining takes place on large boring machines and lathes in a specialised workshop. Here we rely on our 40 years’ experience in working with complex machine components.
