Lincoln Electric Designs New Submerged Arc Flux Specifically for Wind Tower Welding

Cleveland Recognizing the unique demands faced by wind tower manufacturers, Lincoln Electric has introduced Lincolnweld® WTX – a submerged arc flux designed to meet the strict requirements of wind tower welding applications. 

Created for submerged arc welding on wind tower bases and door frames, Lincolnweld WTX provides a number of industry leading features, including:

– Excellent twin and multi-arc AC and DC operations, affording increased productivity when combined with Lincoln™s Power Wave® AC/DC 1000®

– Low temperature impact properties, making Lincolnweld WTX capable of producing Charpy V-Notch test results exceeding 20 ft-lbf (27J) at -80 Û«F (-62Û«C)

– Outstanding performance when welding circumferential and longitudinal butt and fillet welds, providing a multi-purpose flux capable of achieving optimal results on a variety of wind tower seam welding applications

– Smooth bead profile, allowing for the achievement of excellent toe angles, tie-in and bead appearance on interior and exterior applications alike

For maximum performance, Lincoln Electric recommends Lincolnweld WTX be used with the Lincolnweld L-61 electrode on both longitudinal and circumferential seam welds. The combination of Lincolnweld WTX flux and L-61 wire meets the F7A8-EM12K-H8 AWS classification and allows welds to exceed the demanding mechanical property requirements specified for cold weather wind tower applications.

Lincoln also offers another flux/wire combination with Lincolnweld WTX flux with Lincolnweld L-70 wire, which is capable of producing a higher tensile strength, meeting the F8A4-EA1-A3-H8 AWS classification.
