Industrial valves
Metal sealing, geometric precision, and reliability in critical conditions.
Solutions designed for the production of valve bodies and seats with welded coatings (cladding/overlay) intended for severe service: high pressure, high temperature, corrosion, erosion, and H₂S/sour service environments.
LEAS develops systems dedicated to automatic cladding with strict control of linear energy, dilution, and cladding geometry, ensuring uniform thickness, low dilution percentage, and metallurgical integrity of the functional coating.
Cladding processes
TIG hot-wire, PTA (Plasma Transferred Arc), pulsed MIG/MAG, laser cladding
Filler materials
Inconel 625/718, Stellite, Co-Cr, Ni-based alloys, Fe-Cr-Mo
Base materials
Carbon steels, Cr-Mo alloy steels, stainless steel, duplex, superduplex
Level of automation
Robotic cells with positioners, molten bath control, and dilution monitoring
Integration with
Seat turning, grinding, NDT (PT, UT), pressure and leak testing
Average production
6–30 components/hour (depending on DN, coating thickness, and alloy used)
