Automatic systems for the assembly and welding of dished heads on ferrules represent a high-tech solution for the industrial production of tanks, pressure vessels and cylindrical components for sectors such as the chemical, food, pharmaceutical, HVAC and water treatment industries. These systems are designed to ensure high productivity, consistent weld seam quality and process repeatability, even over long cycles and high-throughput batches.
Thanks to advanced numerical control, the systems automatically manage all the operating phases: from the assisted loading of the dished heads, to the insertion of the ferrule, up to the automated assembly and simultaneous circumferential welding of the two heads. The final phase involves automatic unloading onto the roller conveyor, optimizing the entire production cycle and drastically reducing downtime.
The plant is equipped with a precision hydraulic handling system, which guarantees fluid and controlled positioning during each phase, increasing the accuracy of the union between the heads and the ferrule. The integration of a high-precision automatic centering system allows for perfect alignment of components, which is especially critical for butt-to-head joints.
One of the most innovative features is the dual-torch system, which allows simultaneous welding on both ends of the tank, halving time and increasing efficiency. The system can work both on edgebanded and non-edged joints, adapting to the customer's design specifications. The automatic spot welding function is also integrated, which ensures the stability of the workpiece before complete welding.
All process parameters – speed, intensity, torch position – can be controlled via an intuitive touch-screen interface, allowing quick setup and centralized management of the work cycle. These systems can be perfectly integrated from an Industry 4.0 perspective, with the possibility of interconnection to ERP and MES systems for real-time monitoring of production data.
Sitec automatic systems for the assembly and welding of primers on ferrules are tailor-made solutions, designed to ensure high performance, low operating costs and excellent welding quality, in line with the needs of modern industrial productions.
