What Is Orbital Welding
Orbital welding is a highly precise and reliable technique, essential for manufacturing critical equipment that requires exceptional weld quality. Using advanced equipment and specialized techniques, Celli’s Group ensures the structural integrity and durability of welded joints in its projects.
History of Orbital Welding
Orbital welding is an automated GTAW (Gas Tungsten Arc Welding) system, in which a microprocessor controls all parameters during the welding process, ensuring proper material fusion, with the correct and consistent penetration level throughout the tube perimeter. The system also controls the internal purge with inert gas (pure Argon), providing an excellent internal finish and preventing protrusions.
This technology was developed by the aerospace industry for use in rockets and aircraft, primarily in hydraulic controls and fuel piping, due to its reliability and leak-proof properties. Over time, it began to be used in nuclear power plants, semiconductor factories, and, starting in the 1980s, was adopted in pharmaceutical industries, especially in purified water and injectable water lines (PW and WFI), as well as in beverage, food, and cosmetics industries.
Advantages of Orbital Welding
Ensures homogeneous weld quality throughout the system.
Leak-proof sealing.
Smooth internal finish, reducing the likelihood of bacterial colony formation.
Facilitates pipeline cleaning.
Allows the use of various products in the same line.
Reduces system downtime for line sanitization.
Since it is executed in stainless steel 316L, the system can be sanitized with clean steam.
Applications
Orbital welding is widely used in industries where weld quality and integrity are critical. It is currently applied in sectors such as:
Pharmaceutical industry.
Petrochemical sector.
Nuclear power plants.
Automotive manufacturers (paint booths).
Chemical industries.
Types of Orbital Welding
Orbital welding can be applied in different ways, depending on the type of piping and project requirements:
Orbital Welding with Filler Material
Uses a welding wire automatically fed for greater strength and penetration.
Ideal for thicker pipes and structural applications.
Orbital Welding Without Filler Material (Autogenous)
Fuses materials without adding wire, ensuring a homogeneous weld.
Commonly used in small-diameter piping for pharmaceutical and food industries.
Orbital Welding for Thin-Walled Tubes
Developed to prevent deformation in very thin-walled tubing.
Applied in sectors such as aeronautics and semiconductors.
Orbital Welding for High-Pressure Piping
Designed to withstand high temperatures and extreme pressures.
Used in nuclear plants, petrochemicals, and chemical industries.
How to Choose the Right Type?
The choice of orbital welding type and equipment depends on factors such as tube diameter, wall thickness, material type, and quality requirements. Celli’s Group relies on cutting-edge technology to ensure excellence in all orbital welding processes.
Equipment Used in Orbital Welding
The execution of orbital welding requires high-precision equipment, such as:
Orbital Welding Head – Rotates the electrode around the joint to be welded.
Orbital Welding Power Source – Controls current, arc time, and inert gas flow.
Cooling Unit – Prevents overheating during long processes.
Control and Programming System – Adjusts parameters according to material and application.
Inert Gas (Pure Argon or Special Mixtures) – Protects against contamination and oxidation.
