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.
