LE.DI.CA. exports Plasma Key-Hole technology for tube welding

LE.DI.CA., a company specializing in the design and production of custom systems for tube welding, has recently expanded its presence in international markets with a new supply to the United Arab Emirates (Dubai). The system was developed for welding thick-walled tubes in ASTM A358 classes CL-1, CL-2, and CL-5, with diameters ranging from 160 to 505 mm.
Plasma Key-Hole technology for external welding
The system features a triple-cathode PLASMA-PLASMA-TIG torch with cold wire feed, based on Plasma Key-Hole technology. This setup enables single-pass external welding on thicknesses of up to 12 mm, ensuring a high-quality, homogeneous joint free from inclusions.
Quality control with internal TIG torch and integrated camera
To guarantee the internal quality of the weld, the system is also equipped with an internal TIG torch featuring a camera and cold wire feed. This tool allows for inspection of the welded joint and correction of defects such as porosity or inclusions.
The integrated camera enables real-time monitoring of the process by the operator, while the magnetic arc oscillator further improves bead distribution, enhancing both continuity and weld precision.
Innovation and safety in the welding sector
The integration of Plasma Key-Hole technology with TIG torch video monitoring marks a significant advancement in productivity and quality for the tube welding industry.
You can meet CEO Maurizio Catalano in person during the first two days of Stainless Steel World in Maastricht (November 18–20, 2025), a valuable opportunity to explore the full potential of LE.DI.CA.’s innovative systems.
