Description
DESCRIPTION
NK-59 is a solid wire which has been designed to get good usability and are intended for both single and multipass welding. Copper coating ensures problem free wire feeding, smooth current pick-up and minimal contant tip wire. They are especially suited for sheet metal applications, where smooth weld beads are desired and structural and plate steels with high deposition recovery yp to 95%.
APPLICATIONS
For butt and fillet welding of structural steels, and general fabrication such as pressure vessel plates, carbon steel, for intermediate and higher temperature service, or for moderate and lower temperature service.
