The longitudinal welding machines of the BSL FLAT SHEETS – INTERNAL series represent an advanced and highly specialized solution for the longitudinal welding of flat sheets and for the internal joining of large ferrules. These systems are designed to ensure maximum precision and reliability even in the most complex machining, where the geometries of the pieces and the operating conditions require customized configurations and automated welding technologies.
The distinctive feature of this series is the construction architecture that allows the installation of the main beam and the torch carriage inside the ferrule, making longitudinal welding possible from the inside. This configuration is particularly useful in the production of tanks, large diameter pipes and cylindrical structures in the energy, infrastructure, HVAC and plant engineering sectors, where external access to the welding area is limited or inefficient.
BSL FLAT SHEETS – INTERNAL machines are able to join sheets of varying thicknesses and lengths, with diameters that can be adapted according to the model and configuration chosen. This versatility makes them suitable for diversified production cycles and tailor-made welding needs.
To support the process, the machines can be equipped with a hydraulic longitudinal centering device, which ensures the perfect alignment of the edges to be welded, and with hydraulically adjustable side brackets, designed to support the sheet metal during positioning and welding, improving the quality of the seam and operational stability.
The CNC control interface allows complete management of welding parameters and mechanical movements, ensuring precise, continuous and repeatable welding. Integration with MIG/MAG, TIG, Submerged Arc and Plasma welding technologies allows you to work on a wide range of materials and thicknesses, ensuring the highest quality of the welded joint.
Thanks to their modular structure, compatibility with industrial automation and integration possibilities in digitized environments, the machines of the BSL FLAT SHEETS – INTERNAL series are an ideal choice for those looking for production efficiency, operational flexibility and welding quality in complex and large-scale applications.
