At Addit, we perform welding of components, structures, and assemblies used in projects where the quality of welded joints has a direct impact on the strength, safety, and reliability of the finished product.
Depending on the specific requirements of the project, we use TIG, MIG/MAG, robotic welding with collaborative robots, and laser welding technologies. Our broad range of welding capabilities allows us to select the method best suited to the requirements of each specific product, rather than limiting the project to the capabilities of a single process.
We have developed extensive expertise in welding carbon steel, stainless steel, and aluminum. Our team includes specialists with expertise in specific material groups and types of welded joints. At Addit, we ensure strict separation between these material groups. Dedicated welding workstations, tools, fixtures, and grinding booths are used for each type of material to prevent cross-contamination.
Support in Selecting the Best Welding Technology
We consider welding an integral part of the complete manufacturing process. From the project preparation stage, we analyze the material, component geometry, strength requirements, expected surface quality, and intended operating conditions of the product. This enables us to select a welding technology that ensures a stable, repeatable, and economically efficient manufacturing process.
The appropriate selection of welding technology and process sequence helps minimize material distortion, improve manufacturing repeatability, and reduce the need for subsequent finishing operations.
Quality Assurance and Welding Supervision
We have our own welding supervision team with IWE/IWT/IWS competencies in accordance with EN ISO 14731, as well as personnel qualified to perform industrial non-destructive testing in accordance with EN ISO 9712. This enables us to manufacture products subject to stringent quality and safety requirements.
In addition, our team includes more than 80 certified welders qualified in accordance with EN ISO 9606-1 and EN ISO 9606-2, providing high production flexibility and ensuring reliable execution of railway industry projects.

Addit's Technological Capabilities
We perform welding processes using technologies individually selected according to the requirements of each project.
TIG Welding
TIG welding is used wherever the highest level of manufacturing precision and excellent visual weld quality are required. The process is particularly suitable for stainless steel, aluminum, and thin-walled components where minimizing heat input into the material is essential.
MIG/MAG Welding
MIG/MAG welding is used to produce durable joints in steel components. The technology provides high productivity and enables the manufacture of both simple and complex structures while maintaining the required quality standards.
Robotic Welding
For projects requiring a high level of repeatability, we use welding cells equipped with collaborative robots (cobots). Process automation enables stable welding parameters, reduces the influence of human factors, and increases production efficiency.
Manual and Robotic Laser Welding
For selected applications, we also use laser welding, which enables the production of very narrow welds with a minimal heat-affected zone and limited material distortion. This technology is particularly suitable for projects requiring high precision and reduced subsequent mechanical finishing. Laser welding is a key area in the continued development of Addit’s technological capabilities.
How Does the Process Work?
The process begins with an analysis of technical documentation, specifications, and project requirements. Our engineering team evaluates the functional requirements of the product and, based on this analysis, determines the most appropriate welding technology, parameters, and welding sequence for the specific application. Our engineers also advise the customer whenever a process change compared with the original documentation is necessary or recommended. Depending on the project requirements, components are joined using TIG, MIG/MAG, collaborative robotic welding, or laser welding technology.
After welding, finishing operations are performed, including manual or machine grinding of welds and surfaces. The finishing method is selected according to the component geometry and requirements concerning visual quality and surface roughness. For products with particularly stringent visual requirements, we use equipment capable of producing a uniform directional finish with a high level of repeatability.
To restore the required material properties after welding, heat discoloration generated during the welding process is removed. This operation improves the corrosion resistance of the components and prepares their surfaces for subsequent manufacturing stages.
We also perform abrasive blasting in-house to clean and homogenize component surfaces. This process is used wherever high visual quality and low surface roughness are required.
