TIG Welding Components and Process at Asimer Group

At Asimer Group, we approach each TIG weld with meticulous care to ensure that our projects are of the highest quality and durability. Our experienced team of welders, equipped with extensive TIG welding experience, adheres to the highest quality standards at every stage of the process.

Each TIG weld begins with thorough preparation of materials and the welding zone. Our welders rely on specialized cleaning equipment to remove any surface contaminants that may compromise weld quality. Additionally, preheating techniques are employed to maintain optimal temperatures in the welding zone, mitigating the risk of cracks and defects.

Once the materials are prepared, the main event 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.

To protect the welding zone 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 oxide formation 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 end result is a robust joint that meets industry standards.

After welding, we subject each joint to a rigorous inspection process to ensure its quality and integrity. We employ non-destructive testing such as liquid penetrant and radiographic inspections to detect any defects, ensuring that each component meets our strict quality standards.

Non Destructive Test
We use non-destructive tests such as liquid penetrants and radiography to identify potential faults, ensuring that each component meets our rigorous quality criteria.

Each TIG weld at Asimer Group is performed with meticulous attention to detail, ensuring the quality and durability of our products. Our commitment to TIG welding excellence allows us to deliver cutting-edge engineering solutions that meet and exceed customer expectations.
