VOLTAWELD V-9016-G
AWS Specification: E9016-G
JIS Specification: D5816
Other Specification: KS E5816

Applications

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

Characteristics

N-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.

Notes on usage

(1)   Dry the electrodes at 350°C-400°C for about one hour before use.]

(2)   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.

(3)   Keep the arc as short as possible.

(4)   Preheat at 50-150°C before use.

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