The Cutting-Edge Solution for Automated Circumferential Welding
The Valentek CP 2.0 range represents the gold standard for the automated circumferential welding of cylindrical components, piping, and hollow bodies. Engineered to meet the demands of the most rigorous industrial sectors, the CP series delivers high-integrity structural joints, an impeccable aesthetic finish, and process continuity that roots out defects and inconsistencies typical of manual welding.
Through native integration with MIG/MAG, TIG, PLASMA, and SAW processes, CP 2.0 positioners guarantee superior mechanical strength and millimeter-level repeatability, significantly optimizing cycle times even across high-volume production runs.
Applications:
1. Tanks, Dished Heads & Pressure Vessels: Automated circumferential welding of storage tanks, cylindrical shells, dished ends (domed heads), and industrial pressure vessels.
Technical Advantage: The heavy-duty frame and synchronized rotation control deliver a continuous, uniform, and structurally flawless weld bead along the entire 360° perimeter. Perfectly suited for MIG/MAG, TIG, PLASMA, and SAW processes..
2. Industrial Piping, Flanges & Manifolds: Automated joining of pipes, flanges, couplings/sleeves, and tubular assemblies.
Technical Advantage: Featuring an axially movable tailstock and an optional 3-jaw self-centering chuck, the system ensures rapid clamping and millimeter-accurate alignment-completely eliminating concentricity errors and dramatically reducing setup times..
3. Food, Pharmaceutical & Chemical Sectors: High-precision welding of stainless steel hollow bodies, ducts, sanitary piping, and process tanks.
Technical Advantage: Guarantees aesthetically flawless, highly functional joints with a uniform surface finish and zero porosity, fully meeting the most stringent hygienic and sanitary standards required for process fluid handling.
4. Heavy Fabrication & High-Stress Structural Components: Processing of thick-walled structural joints and heavy mechanical components subject to intense vibration and severe operational loads.
Technical Advantage: With an integrated payload capacity ranging from 300 kg up to 800 kg (on CP DH models), the positioner maintains smooth, vibration-free rotation even under maximum weight capacity.
Advanced Control Panel: Millimeter-Accurate Control & Real-Time Vision
The human-machine interface (HMI) of the CP 2.0 series merges the digital intuitiveness of touch controls with the tactile reliability of rapid-action industrial switches, ensuring total and secure management across every phase of the welding cycle:
- Dual-Monitor & HD Vision System: A dedicated upper monitor connects to the process camera for live visual inspection of weld fusion and bead formation, paired with a central Industrial PLC/CNC Touchscreen for complete program and parameter management (speed in mm/min, position offsets, and timing).
- Rapid & Millimeter-Accurate Positioning: Directional pads and dedicated controls allow for micrometric fine-tuning and rapid multi-axis movement (Carriage/Rotation and Horizontal/Vertical), ensuring flawless torch alignment over the joint.
- Workpiece & Torch Rotation Management: Direct selector switches provide immediate control over the rotation of the workpiece cylinder and the 90° swiveling/rotation of the torch axis.
- Best-in-Class Ergonomics & Safety: An industrial control station equipped with high-response physical switches (two-hand safety start, emergency stop button, tailstock actuation, lifter/elevator, and cold wire feed) alongside an integrated USB interface for program storage and data tracking.
| Panel Component | Technical Function | Operational Benefit for the Workshop |

| 7″ CNC Touchscreen | Configuration of position offsets, welding speed (mm/min), jobs, and welding recipes. | Zero setup time, rapid production changeover, and complete lot repeatability. |
| Dual Directional Pads | Micrometric manual positioning for Horizontal/Vertical and Carriage/Rotation axes. | Millimeter-accurate torch alignment prior to initiating the automated cycle. |
| DEDICATED Physical Selectors | Direct control over Cold Wire, Torch Rotation (90°), Tailstock, and Lifter. | Instant actuation without navigating through touchscreen sub-menus. |
| Front USB Port | Import/Export of welding programs, job recipes, and weld logging reports. | Ready for Industry 4.0 / 5.0 data tracking and factory interconnectivity. |
Testing in Action: CP 2.0 Field-Verified Precision
From millimetric calibration to a flawless weld bead: direct technical supervision for zero-defect results.
In cutting-edge industrial welding, specifications on paper only matter when proven in practice. In this video, we take you inside our workshop during the final stages of setup, fine calibration, and live testing of the CP 2.0 circular positioner.
Direct oversight by our founder during machine fine-tuning embodies the Valentek philosophy: over 25 years of engineering heritage rigorously applied to every single machine. From millimetric torch axis adjustment to precise rotational speed control, every detail is tested to guarantee maximum stability and absolute joint repeatability.
