🔩 Precision Orbital TIG Welding Services for High-Purity Pipe Connections

When industries demand high-precision, high-quality pipe welding solutions, orbital TIG welding stands out as the gold standard. At Dev Engineering Services (DES), we specialize in automated orbital welding services for stainless steel and alloy piping systems used in critical sectors like pharmaceuticals, food and beverage, biotech, semiconductors, and high-purity gas manufacturing.

🔧 Understanding Orbital Welding?

Orbital TIG welding (Tungsten Inert Gas welding) is a fully mechanized welding process where the torch moves in a controlled, circular path around the stationary pipe. This technique ensures precise, repeatable, and defect-free welds, especially in tight spaces or complex assemblies.

Our orbital welding systems are designed to meet the stringent hygienic and process requirements of industries that cannot afford even minor weld inconsistencies.

✅ Key Applications of Orbital Welding Technology

Butt welding of stainless steel pipes and tubes
Welding of flanges, elbows, and T-fittings
Sanitary welding of valves and inline components
Ultra-high-purity (UHP) process line welding for semiconductor and biotech industries
Skid-mounted system fabrication requiring uniform weld quality

🔍 Why Choose Orbital TIG Welding for Stainless Steel Piping?

🔹 Superior Weld Quality and Repeatability – Once a weld program is set, our orbital welding system delivers consistent, high-quality welds with virtually zero defects—ideal for cleanroom and sterile processing environments.
🔹 Increased Welding Productivity – Compared to manual welding, orbital TIG welding significantly reduces downtime and minimizes rework, especially on repetitive jobs or complex site installations.
🔹 Lower Operator Dependency – Trained operators—not certified welders—can perform automated orbital welding with precision, reducing costs and skill dependency while maintaining world-class results.
🔹 Works in Harsh or Confined Environments – Orbital TIG welding is ideal for difficult-to-access areas, environments with poor visibility, or radiation zones. Weld heads can be remotely operated and monitored via video feeds.
🔹 Real-Time Monitoring and Weld Traceability – Our orbital welding machines offer complete parameter control, weld logging, and data traceability, enabling integration with quality assurance systems and complying with audit requirements.

🛡️ Shielding and Backing Gas in Orbital Welding

Argon Gas for Shielding: High-purity Argon (99.995%) is used as the shielding gas in TIG orbital welding to ensure arc stability and protect weld quality.
Backing Gas for Weld Protection: The pipe interior is purged with high-purity backing gas to prevent oxidation and discoloration, essential for industries like biopharma and semiconductors.
UHP Standards: For UHP welds, oxygen content must be less than 10 PPM, ensuring a contamination-free environment inside the weld zone. Post-weld passivation is recommended to remove any heat tint caused by residual oxygen.
