PA-9018-M
WS Speicification : A5.5 E9018-M
JIS Specification : NONE
Other Specification: NONE
I. APPLICATIONS:
Welding of 60kgf/mm2 class high tensile strength steel for pressure vessels, bridges, penstocks, vehicles, offshore constructions vehicles and machinery. Fillet tack welding of T1, HY80, HY90 steels.
II. DESCRIPTIONS:
PA-9018-M is an iron powder 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.
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 80-100°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.
