Equipment and spare partsBrowse manufacturers Search by manufacturerFounded in 1984 in Germany, ORBITEC GmbH is a world-renowned manufacturer of specialized equipment for automated orbital TIG/GTAW pipe welding. We deliver comprehensive turnkey systems comprising OSK enclosed weld heads, OSW open heads, Tigtronic power sources, RBK tubesheet tools, Planfix squaring machines, and Oxy residual oxygen monitors worldwide.
The OSK series enclosed weld heads are engineered for automated autogenous orbital TIG welding of thin-walled stainless steel, titanium, and nickel alloy tubing in semiconductor cleanrooms, pharmaceutical processing facilities, and aerospace hydraulic assemblies. The ultra-narrow physical envelope, symmetrical housing, and optimized internal shielding gas flow deliver hermetic gas protection across the entire weld pool, guaranteeing complete absence of heat tint and discoloration.
OSW series open-frame orbital weld heads are designed for multi-pass TIG welding of medium to heavy-wall process piping, elbows, tees, and heavy flanges in thermal power generation, petrochemical complexes, and pipeline construction. The high-rigidity gear-ring drive ensures ripple-free circular torch movement, multi-axis micrometer arc length and inclination adjustment, and fully synchronized cold wire delivery directly into the molten puddle.
Tigtronic digital microprocessor controllers and EVO 200 WP all-in-one power units combine multi-axis CNC welding automation, state-of-the-art inverter power sources, and integrated closed-loop liquid cooling into a rugged transportable enclosure. The architecture features automatic weld schedule generation based on tube dimensions and metallurgy, independent sector programming, and complete Industry 4.0 quality documentation via USB.
RBK series specialized orbital weld heads are engineered for rapid, highly repeatable automated tube-to-tubesheet joint welding in shell-and-tube heat exchangers, condensers, evaporators, and boiler steam drums. An expanding pneumatic or mechanical centering mandrel locks the welding head firmly inside the inner tube diameter, maintaining rigid coaxial rotation and arc stability throughout every orbit.
Planfix series portable tube squaring and facing machines produce flawless end-face perpendicularity and 100% burr-free joint preparation, essential for gap-free autogenous orbital TIG welding. Equipped with quick-clamping concentric collets, micrometer-calibrated tool feeding, and TiN-coated indexable carbide cutting inserts engineered specifically for tough stainless and nickel alloys.
Oxy series residual oxygen analyzers provide real-time digital monitoring of backing purge gas purity prior to arc ignition and throughout the entire orbital welding sequence. Measuring residual oxygen levels down to 1 ppm prevents weld root oxidation, heat tint formation, and chromium depletion, preserving the corrosion resistance of high-purity alloy pipelines.
Orbifeed cold wire feeding units deliver synchronized, pulse-modulated filler wire delivery when operating alongside OSW open-frame weld heads, RBK tubesheet systems, and welding turntables. The robust four-roll wire drive system with integrated digital servo control prevents wire slippage, buckling, and cross-section distortion across all wire alloys.
ORBITEC pipe preparation machinery features S-LT orbital circular saws for cold, chip-free pipe cutoffs without heat-affected zones, alongside TURN 230 S precision rotary welding turntables. The turntables provide smooth, backlash-free rotation and table tilting for both manual and mechanized welding of pipes, flanges, and complex branch fittings.
Our tooling and welding application engineers perform comprehensive cycle calculations based on your architectural piping blueprints and joint metallurgy. We guide you in selecting the ideal weld head configuration (OSK enclosed series for ultra-high purity thin-walled lines or OSW open-frame series for heavy-wall multi-pass joints), sizing the Tetrix 200 or 351 inverter power units, and specifying precision gas purging fixtures tailored to your alloy grades (304L, 316L, titanium, Inconel, and Hastelloy).
ORBITEC automated systems are deployed worldwide across demanding industrial sectors: biopharma process lines (WFI water for injection, clean steam, ultra-pure bio-media), semiconductor fabrication plants (ultra-high purity UHP gas delivery systems), hygienic food processing, and critical tube-to-tubesheet exchanger bundles in thermal and nuclear power plants.
Every mechanical weld head module and digital control circuit from ORBITEC is engineered and assembled in Germany adhering to rigorous runout and positioning tolerances. Tigtronic controllers feature real-time milli-second logging of arc voltage, current, and gas flow, producing verifiable validation reports compliant with GMP and ISO quality assurance mandates.
All authentic ORBITEC orbital systems and accessories are shipped directly from European manufacturing facilities in heavy-duty shock-resistant flight cases, accompanied by comprehensive factory manuals, CE conformity declarations, and metrology calibration certificates, fully supported by robust international freight logistics and customs clearance.
