NIHONWELD N-7016-G
AWS Specification: AWS A5.5 E7016-G
JIS Specification:

D5016

Other Specification:

DIN E5155B(R) 10

 I. APPLICATIONS: 

Welding of LPG tankers, LPG storage tanks, nuclear power plants, bridges and pipe lines in cold regions.

 II. DESCRIPTIONS:

N-7016G is a low hydrogen type electrode for 50kg/mm2 class high tensile steel and Al-killed steel used in temperature up to -45ºC

  • Excellent mechanical properties.

  • Good notch toughness in low temperature.

  • X-ray performance and mechanical usability are good.

III. NOTES ON USAGE:

  • Dry the electrodes at 300-350ºC for one hour before use.

  • Adopt back step method or strike the arc on a small steel plate prepared for this purpose to prevent blowholes at the arc starting.

  • As excessive heat-input deteriorates impact values, weld with proper heat-input selected according to the impact values required.
