Additive Manufacturing Onsite Repair   

The world’s most advanced manufacturing technology for repair

Additive Manufacturing Onsite Repair brings the world’s most advanced manufacturing technology for repair to your plant

Operational disruptions and downtimes are associated with high costs and difficulties for plant operators. Fast, reliable, and straightforward service is crucial for getting plants back into operation as quickly as possible. But spare parts availability might be critical and transporting a valuable component to a workshop can be expensive and a time-consuming logistical operation. Our Additive Manufacturing Onsite Repair solution is designed to restore your critical components – or even improve their performance – onsite using the advanced additive manufacturing technology.

At a glance

Our Additive Manufacturing Onsite Repair  solution is designed to enable challenging and value-adding repairs to be carried out onsite.

It saves customers long delivery times and investment costs by using advanced additive manufacturing processes onsite.


Additive Manufacturing Onsite Repair – a unique process intended to restore the original condition of components of any dimension onsite – offers new repair possibilities for power plants and many other industries.

Our solution uses mobile robotics systems that enable both small and large components to be repaired onsite. The system comprises a robot, an additive device/welding head and a control system. It can be combined with a variety of equipment, such as a turntable or a rotation drive, to meet specific needs. The entire system can be deployed to the site and assembled along with a mobile protection system. It designed to be ready to start work within several hours.

Affected components refurbished and finished using modern additive manufacturing processes.

Mobile robot assisted systems like robotic laser cladding or Wire Arc Additive Manufacturing technologies help enable the repair of components worldwide using additive manufacturing processes.

Thanks to modern technologies, limited distortion and heat affects are expected, and the original condition of the component is restored.

Additive Manufacturing (AM) is an emerging and innovative manufacturing process that differs fundamentally from conventional approaches. 

Components are built or restored layer by layer which can result in enormous flexibility. Different onsite processes are available, like laser cladding or Wire Arc Additive Manufacturing technologies.

A thin layer of the substrate is melted in a controlled manner by a laser. This is designed to form a metallurgical bond between the substrate and the component. The absorbed metal powder produces deposit on the surface.

Different powders can be premixed before injection, or several different powders can be used to create a custom alloy. By combining different metals and alloys, sandwich structures can be produced. Material combinations that are difficult to achieve with traditional methods can be generated with laser metal deposition.

The base materials for laser cladding will be qualified and used by Siemens Energy depending on the application.

Wire Arc Additive Manufacturing (WAAM) uses an arc welding process to 3D print metal parts. It enables the production and repair of large parts with structural integrity.

Application of a highly precise laser beam is designed to limit the amount of heat – generated during the process, which is a significant advantage over conventional processes.

The robotic laser application helps promote fast and accurate processing. In addition, the solution can be used with almost all component geometries.

On-Site Machining plays a key role for helping promote high availability, long service intervals and the shortest possible repair times and costs.

It is intended to save valuable time for transport, and plant operators are ideally equipped to deal with any possible findings or planned downtimes in their plants.


Key intended benefits

Our technological edge begins where we leave standard solutions behind. We began working on On-Site Machining decades ago and have used a succession of proprietary developments. This approach is crucial if we are to meet the ever-increasing precision requirements.

For us, reliability begins with precision. And with the sense of responsibility that comes with offering you the best possible service wherever you may need us. And we believe reliability also means working with verified, clearly structured processes and checking our improvements at regular milestones – all with the objective of getting your plant up and running again faster than ever.

By capturing and analyzing large amounts of data and applying new measurement techniques or innovative 3D models, our On-Site Machining services can be even more efficient and valuable for our customers.

Additive Manufacturing Onsite Repair is suitable for various applications. 

The process is particularly suitable for power plant components but also for many other industries. When spare parts are not available or it is crucial to restore the original condition of a component, the onsite repair solution is beneficial.

Restoring the original journal diameters without a bearing shell exchange. 

Saving the replacement of a component and thus a significant amount of crucial uptime.

Potential to restore gas turbine, steam turbine or generator rotors to their original geometries and usability onsite.

Precisely to the point

Since laser metal deposition is designed to allow the amount of energy to be precisely metered and applied to precisely defined areas of the substrate, only a small amount of heat is generated. This is designed to allow components to be refurbished without altering them.

Application examples

Onsite Journal Repair helps enable the rectification of scoring marks or damages without a journal exchange. The repair is intended to restore the original journal diameters to promote optimal operation. For a successful repair, it’s crucial to precisely meet the tolerances for diameters, all other geometric dimensions and all welding requirements for surface and material quality. Structural properties, such as hardness, are retained. The Additive Manufacturing Onsite Repair technology is tailored to meet these demands and can help save the customer both time and money.

Restoring the original state in five steps:

  1. Fact finding and evaluation /determination
  2. Pre-machining of affected rotor area by turning
  3. Laser Cladding Process
  4. Final machining to the original diameter
  5. Non-destructive Testing (NDT)

The individual components of rotating equipment are crucial for their reliable and efficient operation. Onsite Component Repair is an excellent solution to refurbish critical components, like gas turbine parts, that are designed to ensure the correct flow of air streams. Wear on these components can affect the safety and efficiency of operation since misdirected cooling air can cause inadequate cooling of the rotating blades and a loss of power. Onsite Component Repair is intended to save the exchange of the component and a significant amount of crucial uptime. Our team of service specialists addresses the entire process, from disassemble to assemble and recommissioning.

Faster and more cost effective:

  • Use of mobile additive manufacturing systems is intended to enable the optimization of mechanical properties of weld material in relation to base material, and is expected to offer better resistance against wear (depending on the processes and additives used)
  • Total duration of entire process expected to be within the outage schedule
  • Total repair costs are estimated to be beneficial compared to a replacement

Onsite Rotor Refurbishment is considered the ideal solution when a rectification is to be carried out without exchanging the entire rotor. For gas turbine, steam turbine, or generator rotors, the original diameters can potentially be restored. The exact tolerances for diameter and all other geometric dimensions are met and all welding requirements for surface and material quality may be fulfilled. In addition, structural properties, such as hardness, are retained. Customers thus intended to save valuable time and money. Our team of service specialists addresses the entire process, from disassemble to assemble and recommissioning.

Restoring the original state in four steps:

  1. Pre-machining of affected rotor area by turning
  2. Laser Cladding Process
  3. Final machining to the original diameter
  4. Non-destructive Testing (NDT)
