Application overview
Built for seam integrity, sealing reliability, and repeatable inspection performance.
In pressure vessels, storage tanks, and heavy manufacturing, longitudinal seam welding and internal or external circumferential seam welding place strict demands on weld strength, leak-tightness, consistency, and non-destructive testing acceptance. MISA's automated welding systems are engineered to help manufacturers handle vessel seam welding challenges across different vessel diameters, lengths, wall thicknesses, and production volumes.
Longitudinal Seam Welding
Automated torch positioning and controlled travel support straight, stable welds along vessel shell seams and large cylindrical assemblies.
Circumferential Seam Welding
Welding rotators and manipulators work together to deliver uniform rotation and precise torch alignment for internal and external girth welds.
Heavy Fabrication Fit
Suitable for pressure vessel production, storage tank manufacturing, heavy equipment fabrication, and precision engineering workshops.
Core equipment & solutions
Advanced welding manipulators at the center of the vessel seam welding station.
MISA applies advanced welding manipulators to provide accurate, stable, and repeatable automated welding performance. The column and boom structure moves the welding head into position for large vessels, long longitudinal seams, and demanding circumferential welds.
Movement
Precise column and boom extension
Integration
Manipulator and rotator coordination
How the automated station works
Precision movement and enhanced reach
The manipulator's column and boom extension system delivers the torch to internal or external welding positions, covering long seams and complex circular weld paths.
Stable trajectory tracking
Smooth motion and reliable positioning help maintain consistent weld quality for different vessel sizes, materials, and production requirements.
Seamless coordination with welding rotators
Rotators turn the vessel at a steady speed while the manipulator positions the welding torch, forming a complete automatic vessel seam welding workstation.
