What is TIG welding?
TIG welding (Tungsten Inert Gas) is an advanced technology that provides clean and precise welds, making it ideal for industrial applications where quality and structural integrity are essential.
At Asimer Group, a respected company in the field of engineering and machining, we utilize TIG welding to ensure maximum precision in the manufacturing of components for pumps, compressors, and industrial valves.
TIG welding uses a non-consumable tungsten electrode and an inert gas, typically argon, to shield the welding area from contamination. This process allows for precise, high-quality welds, especially for sensitive and delicate materials.
This advanced technique has become an indispensable part of our manufacturing process, ensuring the structural integrity and durability of our projects from the outset. Whether we are designing blueprints or finalizing production, TIG welding is our choice to meet and exceed the industry’s stringent standards.
Our firm commitment to excellence has driven us to efficiently incorporate TIG welding into all our operations. With this advanced technique, we achieve unmatched precision and control in every weld joint. This not only allows us to meet but exceed customer expectations in terms of strength, reliability, and performance.
TIG welding provides us with the flexibility to join a variety of materials with exceptional consistency and quality. From stainless steel to aluminum and specialized alloys, our expertise in TIG welding enables us to work with diverse materials, adapting our approach to meet the unique needs of each project.
Furthermore, TIG welding allows us to meticulously control the temperature and filler material feed rate, resulting in flawless welds that are both clean and highly resistant to corrosion. This meticulous attention ensures the quality and durability of every piece we produce.
TIG welding is not just a technique at Asimer Group; it is a cornerstone that drives our ability to deliver top-quality products to our clients.
TIG welding process and quality certified at Asimer Group
At Asimer Group, we approach each TIG welding project by strictly following the welding specifications provided by the client in the corresponding project, as well as the Inspection Test Plan (ITP), which outlines the WPS (Welding Procedure Specification) and PQR (Procedure Qualification Record) to be followed. This ensures that our projects meet the highest standards of quality and durability.
Our experienced team of welders, highly skilled in TIG welding and backed by ISO 3834-2 certification, plays two fundamental roles: repairing cast parts (correcting porosities or defects from machining processes) and performing special overlays (using nickel and cobalt-based materials). These solutions are renowned for their high surface resistance and certified quality.
Each TIG weld begins with a thorough preparation of the materials and the welding area. Our welders rely on specialized cleaning equipment to remove any surface contaminants that could compromise the quality of the weld. In addition, preheating techniques are used to maintain optimal temperatures in the welding area, mitigating the risk of cracks and defects.
Once the welding area and filler materials are prepared, the key moment arrives: the TIG welding process itself. Our skilled welders use non-consumable tungsten electrodes to create the welding arc, ensuring precise control over weld penetration and bead shape while managing passes and corresponding temperatures.
To protect the weld area from atmospheric contamination, we use high-quality inert gases such as argon or helium. These gases create an oxygen-free environment around the welding arc, preventing the formation of oxides and ensuring clean, high-quality welds.
Throughout the welding process, we meticulously monitor the temperature and filler material feed rate to ensure proper fusion and uniform heat distribution. The final result is a robust joint that complies with industry standards.
After welding, each joint undergoes a rigorous inspection process to ensure its quality and integrity. We employ non-destructive testing methods such as VT (Visual Testing) and PT (Liquid Penetrant Testing), and for more demanding requirements, volumetric tests such as radiographic inspections (Rx) to detect any defects. This ensures that each component meets our stringent quality standards and complies with customer requirements, typically based on ASME or UNE-ISO standards.
