Other Specification: DN E5121RR11160

Description

Application

Remarks

  • Adjust the welding current to keep the proper slag covering because optimum welding current is subject to the welding process and the surface condition of steel plate
  • In the case of horizontal fillet welding, keep the optimum speed ratio among 1.0 ? 1.5
  • Dry the electrodes at 70 ? 100 C for 30 ? 60 minutes before use because excessive moisture absorption causes undercut and irregular beads

Typical data and test results for mechanical properties, deposit, or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design, and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
