Specification

AWS Specification: AWS A5.1 E6013
JIS Specification: D4313
Other Specification: N/A

Description

Application

Remarks

  • Pay attention not to exceed the range of proper currents
  • Welding with excessive current not only lowers X-ray soundness, but also results in spatter, under-cut, and insufficient slag covering
  • Dry the electrodes at 70-100 degrees C for 30-60 minutes before use
  • Excessive moisture absorption lowers usability and may result in porosity
  • Excessive drying before use causes less penetration and overheating of the electrode
  • For Philippine market only

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.
