Working with special materials such as titanium, aluminium and high-hardness coatings requires advanced technical knowledge, specialised equipment and qualified welding procedures. At METALBRAGA Group, we master the specific techniques for each material, ensuring structural joints that preserve the mechanical, chemical and thermal properties inherent to these high-performance materials used in critical applications.
Our experience ranges from aerospace titanium components requiring millimetric tolerances, to aluminium structures for the transport industry, as well as protective coating applications that extend the service life of equipment exposed to harsh environments. Each material presents unique challenges that require specific protocols for preparation, welding and quality control.
Technical expertise in high-performance materials that combines certified procedures, rigorous atmospheric control and non-destructive testing to guarantee structural integrity in critical applications where failure is not an option.
Titanium offers an exceptional strength-to-weight ratio with excellent corrosion resistance, aluminium provides lightness and superior thermal conductivity, while special coatings protect against wear, corrosion and high temperatures. The correct selection and application of these materials determines the performance and durability of critical components in demanding sectors.
Technical Capabilities in Special Materials
Our specialised team works with qualified welding procedures (WPS/PQR) specific to each material, using controlled atmospheres when necessary and applying post-weld heat treatments according to technical specifications. Each project is individually assessed to determine the optimal process that ensures the required properties.
- Titanium Welding: Commercial Grades and Aerospace Alloys with Inert Atmosphere
- Aluminium Welding: Series 5xxx, 6xxx and 7xxx with TIG and MIG Processes
- High Hardness Coatings: Application by Arc Welding and Thermal Processes
- Pollution Control: Controlled Atmosphere Chambers and High Purity Gases
- Non-Destructive Testing: Radiography, Ultrasonics and Penetrant Liquids
We implement comprehensive quality controls that include visual inspection, non-destructive testing and mechanical testing when required. All our procedures are documented and traceable, complying with aerospace, automotive and other critical sector regulations. Our commitment is to deliver components that meet or exceed the most demanding market specifications.
