AWS Specification: E7016-A1
JIS Specification:

DT1216

Other Specification:

BS MoBH

 I. APPLICATIONS:

Welding of 0.5% Mo steel used for high temperature and high pressure boilers, chemical and oil refining industries.

 II. DESCRIPTIONS:

N-7016-A1 is a low hydrogen type electrode for all-position welding which provides the weld metal containing 0.5% Mo.

III. NOTES ON USAGE:

  • Dry the electrodes at 325-375ºC for about one hour before use.

  • Preheat at 100-200ºC and postheat at 620-680ºC.

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

  • Keep the arc as short as possible.
