The orbital welding machine provided by KEPUNI, it can cut off the contact between the human body and light radiation, to reduce the use requirements of welders through the automatic parameters of the expert database so that novices can quickly weld high-quality welding seam and the post-processing of welded pipes is extremely simple to reduce the pollution caused by more than 80% of the environment.
The KEPUNI XD-20W orbital welding machine is engineered to enhance operator safety and weld quality through automated parameter control and a sealed design.
Key Specifications:
Pipe Diameter Range: 3.175 mm – 168 mm
Wall Thickness: 0.5 mm – 3 mm
Welding Intervals: 12 precision-tuned segments ensure consistent bead quality across diverse joint geometries.
Optional Welding Heads: 5H, 10H, 40, 80, 120, 170 (customizable for specific applications).
Advanced Features:
Expert Database AutomationPre-loaded welding parameters adjust voltage, current, and speed in real time, eliminating manual calibration and reducing training time by 70%.
Real-Time Data LoggingRecords welding parameters (voltage, current, travel speed) for each interval, enabling post-weld analysis and process optimization.
Low-Residue WeldingMinimizes spatter and oxidation, streamlining cleaning and reducing hazardous waste.
Applications:
Pharmaceutical: Welds sanitary stainless steel tubing for bioreactors.
Semiconductor: Joins high-purity gas delivery lines in cleanrooms.
Chemical Processing: Repairs corrosion-resistant alloy piping in reactor vessels.
