Uhlig Wel-Cor GmbH
About
Uhlig Wel-Cor GmbH, based in Langelsheim, Germany, is a specialist manufacturer focused on weld overlay cladding and boiler pressure part fabrication for waste-to-energy and industrial thermal plants. Operating under the tagline "The Cladding Experts," Uhlig applies advanced welding technology to produce corrosion- and erosion-resistant cladding on tube-web-tube walls, individual tubes, and flanges, with plating lengths reaching up to 10 meters. Their cladding process achieves low dilution and uniform layer thickness, protecting critical boiler surfaces exposed to aggressive flue gases and thermal cycling. Beyond cladding, Uhlig manufactures complete boiler pressure parts to customer specification, including steam drums with internals, headers and distributors, convective heating surfaces such as evaporators and superheaters, access doors with tube bending and sealing boxes, grate edge tubes, and custom-shaped parts with welded flanges and measurement nozzles. Since 1997 the company has accumulated over 100,000 square meters of completed weld cladding surface area, serving waste-to-energy operators, boiler OEMs, and plant engineering firms primarily across Europe. Uhlig also maintains an active apprenticeship program, reflecting ongoing investment in skilled welding trades.
