Mechanical Engineering RDI Services

We help you assess whether your products are suitable for robotic welding, whether modifications are required, or whether a completely new, robot-friendly design is needed. As part of the assessment, we typically also evaluate what type of robotic system would best suit your company’s needs.

We act as your partner and support you when considering welding automation. Our experts assess, evaluate, and guide you in identifying the most suitable solutions from your company’s perspective, particularly in terms of equipment capabilities. We can support you throughout the entire procurement process, including feasibility assessment, planning, investment evaluation, and implementation, either comprehensively or to the extent you require.

Savonia’s versatile equipment enables testing and validation of different process alternatives, as well as the execution of welding procedure trials. Our materials laboratory supports the testing required for welding procedure qualification, along with advanced imaging, metallurgical analysis, and, for example, corrosion testing.

“

Using our simulation and offline programming tools, we can test and evaluate planned automation solutions already before implementation. With our flexible and reconfigurable robotic system, we validate applications and processes and ensure that the selected equipment meets your company’s requirements. Our key areas of expertise include arc and laser welding.

We have extensive knowledge and expertise in programming robotic systems. We work with you to define the required programming solutions. We provide training for a wide range of robot brands and welding equipment. In terms of offline programming solutions, we offer practical, production-oriented training and, when needed, support you during implementation.

We have a comprehensive understanding of the requirements that robotics places on welding fixtures as well as other stages of production. We provide training, support, and guidance in the development of welding production processes, ranging from individual products to large-scale concepts.

Tensile testing is used to determine the strength properties of materials and their behaviour under load. The determination of material properties is essential for defining application-specific requirements and for quality control.

• Static tensile testing at room temperature is performed using a load frame in accordance with the SFS-EN ISO 6892 standard.
• Fatigue testing (cyclic tensile loading)
• Tensile tests to determine mechanical properties are conducted using standard test specimens. In addition, the strength properties of finished structures or products can also be evaluated.
• Our equipment includes:
  • Matertest FMT – MEC 100, static tensile testing 1–100 kN
  • Walter & Bai LFV 500, static tensile testing 10–500 kN and fatigue testing 10–400 kN

a) Matertest 100 kN and b) W+B 500 kN

Hardness testing enables us to perform the following standard-compliant hardness tests for metals using our equipment:

• Rockwell hardness testing (HRB and HRC) in accordance with SFS-EN ISO 6508-1, suitable for routine testing of hard materials.
• Brinell hardness testing in accordance with SFS-EN ISO 6506-1, suitable for wear-resistant steels and non-homogeneous materials due to the large indentation size.
• Vickers hardness testing in accordance with SFS-EN ISO 6507-1, suitable for both soft and hard materials.
• Reporting according to agreement.
• Our equipment includes:
  • ERNST AT 130 DRN, Brinell hardness HB 30
  • Mitutoyo HR-300, Rockwell hardness HRC
  • Struers Duran Scan-20, Vickers hardness

Vickers hardness tester

• Impact testing is carried out using a Charpy impact tester in accordance with the SFS–EN ISO 148-1 standard.
• For impact testing, a standard V-notch test specimen is prepared from the material.
• The Charpy impact test provides the absorbed impact energy in Joules, indicating the material’s toughness.
• Testing range of the impact tester: 0–150 J
• Reporting according to agreement.

Neutral salt spray testing (NSS) in accordance with the SFS–EN ISO 9227 standard, using a 5% salt solution.

The corrosion resistance of metallic materials, whether coated or uncoated, can be tested under controlled artificial conditions using salt spray testing. Salt spray tests are commonly used for rapid corrosion evaluation, particularly when analyzing discontinuities, pores, or defects in organic and inorganic coatings.

• Testing for samples provided by the customer.
• Imaging of test specimens before and after testing.
• At the end of the test, the extent of corrosion is determined in accordance with the standard, providing a measure of corrosion resistance.
• Reporting according to agreement.

Our modern and versatile 3D printing environment provides excellent capabilities for 3D printing of polymers and composite materials, both at small and large scales. Our equipment includes 3D printing technologies based on material jetting, powder bed processes, photopolymerization, and extrusion.

For large-scale printing, our robotic printing cell also enables hybrid manufacturing, combining printing and post-processing by milling within the same production cell.

We utilize modern metal additive manufacturing systems based on both powder bed technologies and directed energy deposition. Typical materials in powder bed fusion include stainless steel, tool steel, and aluminum.

In wire-based directed energy deposition (WAAM), our expertise is among the leading in Finland.

We provide 3D modeling as well as product and mechanical design services for companies’ R&D needs. As a result of the design process, the customer receives 3D models and/or technical drawings, or even a ready-made product.

We provide 3D scanning and related services, including on-site measurements at the customer’s premises when needed.

Savonia offers materials testing services for 3D-printed components in collaboration with the Material Research Centre Materia.
