A pressure vessel doesn’t get a second chance at its weld seams. That is why pressure vessel welding automation matters for every fabricator working to ASME, IBR or PED codes. Drupe Engineering builds the turning rolls, nozzle welding SPMs, long seam welders and internal-access column-and-boom systems that hold a vessel shell steady and give the weld head consistent access, seam after seam.
Approved supplier to L&T, Godrej, ESAB and ABB Robotics. Every system engineered and fabricated at our 300-ton MIDC Taloja floor.
1. Circumferential Seam Welding Turning rolls and column-and-boom systems for circ seam welding on shells, heads and tanks. Submerged arc and TIG processes with stable travel speed and heat input across the full circumference.
2. Longitudinal Seam Welding Column-and-boom manipulators and seam welders for long straight welds on vessel shells and heat exchangers. Internal and external weld heads run in a single setup.
3. Nozzle Welding SPMs Special purpose machines for nozzle-to-shell and nozzle-to-head welds. Rotary axis and linear column position the torch around the nozzle intersection, holding arc parameters through the full contour.
4. CNC Bevel Cutting for Weld Prep Gantry and table-type CNC plasma and oxy-fuel machines for plate profiling and bevel prep. Drupe’s Gen-3 bevel head cuts the weld groove in the same pass as the profile.
5. Turning Rolls and Positioners Self-aligning and adjustable turning rolls for vessels up to heavy tonnage. Rotary positioners and tail stocks hold the workpiece on centre for consistent weld access.
From your first drawing to lifetime service, every project runs the same disciplined path.
A vessel shell that shifts mid-weld or a nozzle joint that drifts out of tolerance doesn’t just cost rework, it costs a failed hydro test. Drupe’s turning rolls hold the shell steady, our nozzle SPMs handle the curved geometry that off-the-shelf robots struggle with and our long seam systems hold arc distance from the first pass to the last. Approved supplier standing with L&T, Godrej, ESAB and ABB Robotics means the same engineering discipline that passes their audit trail is built into every vessel-fabrication system we ship.
Yes. Our turning rolls and rotary positioners are sized to your vessel diameter and shell weight, engineered to hold position steady through full circumferential welds without drift.
Yes. Nozzle welder and head welder SPMs are a significant part of what we build. If your vessel geometry needs a custom fixture or weld head positioning system, we design it around your drawing.
Every system ships with mechanical drawings, electrical schematics, PLC programs, calibration reports and weld process documentation, built to support your quality audit trail.
