Rotor Repair

Over several decades, Vibrotech has developed innovative repair methods for all types of rotating equipment. All these methods have been meticulously tested and qualified to ensure they provide optimal quality while remaining cost-effective.

Welding options

Vibrotech has the technology and capabilities to repair shafts using two primary welding methods:

• The narrow groove method is used for replacing damaged shaft ends with mechanically matching stub shafts. This welding method is also used for isolated repairs of damaged shaft areas.
• The submerged arc overlay method is very successful in a wide range of repair situations. It is used when a surface area has been compromised, or when an entire integral disk has to be removed and subsequently rebuilt.
