PA-12016-G

AWS Specification: AWS A5.5 E12016-G

JIS Specification :  Z3211 E8316-G

Other Spcification:

 

I.  APPLICATIONS;:;;::: 

For heat treatable low alloy steels, such as SCM21/4 chrome-molybdenum steel, SNCM8 Ni-Cr-Mo steel, high tensile steels such as WEL-TEN80/80C/80P/80E, ASTM A486 Gr120/A508 Gr5a.4a/A543 GrB3.C, etc.

II. DESCRIPTIONS:

PA-12016-G is a low hydrogen electrode for the welding of 830N/mm2 grade high tensile steel in all positions. Good crack resistance and mechanical properties, and good X-ray soundness can be secured because of the low hydrogen content of weld metal.

III. NOTES ON USAGE:

  • Dry the electrodes at 300-350°C for 30-60 minutes before use.

  • Take the backstep method or strike the arc on a small steel plate prepared to prevent blowholes at the arc starting.

  • Keep the arc as short as possible.
