AWS Specification: AWS A5.1 E7016-1
JIS Specification:

NA

Other Specification:

NA

I. APPLICATIONS:

Welding of aluminum-killed steels for low temperature service (N-TUF 33) for tructures to be used in frigid area, offshore structures and cryogenic storage tanks.

II. DESCRIPTIONS:

N-7016-1 is a low hydrogen type electrode for all positions. Deposited metal contains titanium and boron and shows high toughness at -60 deg C and excellent CTOD (crack tip opening displacement) value.

III. NOTES ON USAGE:

  • Electrodes should be redried at 350-400 deg C for60 minutes

  • Optimum heat input in accordance with service conditions and plate thickness of structure should be applied in order to obtain desired toughness and CTOD value. Arc length should be kept as short as possible.

  • Overlap method should be applied at the joining part of the bead.
