Maintenance Welding

Life is competition - Ben, Olympic Museum Lausanne, Switzerland

Take advantage of our experience and our data base with more than 600 maintenance and repair cases.

Main maintenance types and strategies:
Maintenace Welding - an efficient support

Corrective maintenance

  • Corrective maintenance: Maintenance carried out after fault recognition and intendes to put an item into a state in which it can perform again (Reactive maintenance, break down mode)
  • Repair: Physical action taken to restore the required function of a faulty item.

 Procedures and supervision are key factors for success

  • Deferred maintenance: Corrective maintenance, delayed in accordance with given maintenance rules

Preventive maintenance

  • Preventive maintenance: e.g. changing components at predetermined intervals
  • Scheduled maintenance: Preventive maintenance carried out in accordance with an established time schedule or established number of units of use

Preventive and corrective maintenance
Preventive and corrective maintenance

  • Predetermined maintenance: Preventive maintenance carried out in accordance with an established time schedule or established number of units of use but without previous condition investigation
  • Condition based maintenance: Preventive maintenance based on performance and/or monitoring (change or repair just prior to failure)
  • Predictive maintenance: Condition based maintenance carried out following a forecast
    Predictive maintenance significantly reduces maintenance expense and increases operating performance.

Proactive maintenance

  • Proactive maintenance: Predictive maintenance combined with improvements

Less than 10% of manufacturing facilities practice a proactive maintenance strategy; the vast majority is reactive or planned maintenance.

Best practice - our approach to success

Best practice can be applied through copying, re-engineering or the development of better solutions.
Reshaping maintenance activities needs a clear understanding of modern methods and procedures.
They are documented in a systematic manner.

Wear Management: Let's be champions of change and improvement!

Availability and performance improvement as well as maintenance and spare part cost reduction through scheduled, predictive or proactive maintenance, combined with an easy-to repair approach are realistic results of cost-effective wear-management.

Many Original Equipment Manufacturers (OEM) still consider ferritic, martensitic or even austenitic steels as wear resistant. For many years, scientific efforts were focussed on these steels, their weldability and use.

but they can be optimised by an efficient wear-management

Recently, the tendency changed and it was generally accepted that wear could be located in such a way that expensive components are no longer in direct contact with heavy wear mechanisms.
Surface protection by coating is the new proactive trend increasing LifeTime, Availability and Mean Time to Repair or Failure (MTTR or MTTF) of expensive machinery components.
