Characteristics and Application

AWS A5.17 F7A6 EC1 Flux Cored Arc Welding Wire is a metal cored wire for submerged arc welding designed for welding 490N/mm2 grade high tensile steel and low temperature steel, the application is similar to solid wire classification EM 13K. It provides high deposition rates as compared to the solid wires of equal size, with the same amperage, electrical stick out and flux. Welded with SAW flux that provides smooth bead appearance, high porosity resistance and excellent low temperature impact toughness at -500C. Typical applications include structure steel, bridges, tank fabrication, shipbuilding and offshore fabrication.

Notes on usage:

1. To keep the toughness, the plates should not be welded with excessive heat input.
2. If the flux is affected by moisture pickup, it must be re dried at temperature between 300 and 350 0C for 1 hour.

3. Keep the product dry, while it is stored or delivered.
