P-9016-G

AWS Specification: AWS A5.5 E9016-G

JIS Specification : NONE

Other Spcification: NONE

 

I. APPLICATIONS:

Welding of 60kgf/mm² class high tensile strength steel for pressure vessels, penstocks, bridges, offshore constructions vehicle and machinery.

II. DESCRIPTIONS:

P-9016G is an extra low hydrogen type electrode for all-position welding, which provides good notch toughness of weld metal at low temperature. The usability and X-ray soundness of weld metal are good in all-position welding.As the hydrogen content of the weld metals is especially low, the crack resistability is 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 particular purpose because arc striking on the base metal is in danger of initiating cracking.

• Keep the arc as short as possible.

• Preheat at 50-150°C before use.

• Pay attention not to exceed proper heat-input because excessive heat-input causes deterioration of impact values and yield strength of weld metal.
