Specialists in Machining Components with Added Material
At Arri, precision and innovation are present in every component we manufacture. Our machining of components with added material is a clear example of how we combine experience, technology and advanced materials expertise to deliver solutions that exceed the most demanding industrial standards.
Machining with added material
At first glance, the concept may seem straightforward: material is added to a base component and then shaped through machining. In reality, however, the process is far more complex. It requires careful planning, in-depth knowledge of materials and absolute control at every stage.
The filler material, such as Inconel, special steels or alloys resistant to corrosion and high temperatures, is carefully selected and applied only where required. It is then consolidated using advanced welding or deposition techniques and finally machined to exact tolerances.
The result is reinforced, durable and highly precise components capable of withstanding extreme temperatures, friction or mechanical stress.
Added material: more than reinforcement
One of the key benefits of added material is its ability to optimise resources and reduce costs. Instead of manufacturing an entire component from expensive materials, only the critical areas are reinforced. This not only improves strength and durability but also allows each component to be adapted to specific requirements.
For example, Inconel, known for its resistance to corrosion and high temperatures, is used in components operating in extreme environments, ensuring reliability and long service life without compromising the functionality of the original part.
Precision at every stage
Machining with added material is never improvised. For these types of components, in which Arri works closely with its customers, a rigorous process is followed:
-
Base component analysis: study of geometry, tolerances and stress points.
-
Material selection: choice of the most suitable alloy according to the component’s requirements.
-
Controlled application: precise deposition or welding of the material.
-
Final machining: the component is machined to meet exact tolerances and achieve high-quality finishes.
Each stage is carefully controlled to ensure the final result meets the highest engineering and manufacturing standards.

Benefits for the customer
Machining with added material offers clear advantages for customers, particularly for components subjected to extreme operating conditions. By reinforcing specific areas of a component, durability and resistance are significantly increased, ensuring reliable performance in high temperatures, mechanical wear or corrosive environments.
This approach also enables efficient optimisation of materials and costs. Rather than manufacturing the entire component from high-value alloys, high-performance material is applied only where necessary, maintaining the balance between technical performance and economic efficiency.
Another major strength of added material lies in its adaptability to the specific needs of each project. Every component can be customised according to its real application, adjusting reinforcements, geometries and tolerances to respond precisely to operational requirements.
The entire process is underpinned by complete confidence in the quality of the final result, supported by the team’s experience, the use of cutting-edge technology and exhaustive control at every stage of manufacture. In this way, each project is developed as a bespoke solution, designed to ensure performance and reliability from design through to final production.
