Specialised welding is a critical process in modern industrial manufacturing, where the precision and quality of joints determine the structural integrity and performance of essential components. At METALBRAGA Group, we master three fundamental welding processes: TIG (GTAW), MIG (GMAW) and Manual Electric Arc, each strategically selected according to the technical demands of the project, the base material, and the applicable certification requirements.
Our experience of over 20 years enables us to work with high-performance materials such as carbon steel, stainless steel, aluminium, magnesium, titanium, copper, and brass, ensuring certified joints that comply with the most stringent regulations in sectors such as aerospace, automotive, plastics, and glass.
Certified welding processes that ensure critical joints in noble materials, combining technical precision, high productivity and operational versatility for the most demanding industrial projects.
Each welding process offers specific advantages: TIG provides millimetre-precision welds on noble materials, MIG ensures high productivity with consistent quality in serial productions, and Manual Electric Arc offers unparalleled versatility both in the workshop and in the field, adapting to challenging conditions.
Specialised Welding Processes
The selection of the appropriate welding process is essential to ensure structural integrity, operational efficiency, and compliance with technical specifications. Our team of certified welders evaluates each project considering the base material, thickness, welding position, finishing requirements, and applicable regulations.
- TIG Welding (GTAW): Extreme Precision for Critical Joints in Noble Materials
- MIG Welding (GMAW): High productivity with consistent quality in series production
- Manual Electric Arc: Complete Versatility in Workshop and Field
- AWS certifications, ISO 9606 and specific sector regulations
- Quality control through non-destructive testing (NDT)
All our processes are supported by international certifications and qualified welding procedures (WPS/PQR), ensuring complete traceability from material preparation to final inspection. We implement rigorous quality controls through non-destructive testing, ensuring that each weld meets or exceeds the standards required by our clients and applicable regulations.
