PA-10018-M

AWS Speicification : A5.5 E10018-M

JIS Specification : NONE

Other Specification: DIN 8529 EY 7976 Mn2Ni1.5CrMoBH5

 

I. APPLICATIONS:

Welding of 70kgf/mm² class high tensile strength steel for pressure vessels, penstocks, bridges, offshore constructions and industrial machinery.

II. DESCRIPTIONS:

PA-10018-M is an iron powder low hydrogen type electrode for all-position welding. Its ustability and X-ray soundness are very good. It provides weld metal of good metal notch toughness and of high crack resistability.

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 100-150°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.

IV. TYPICAL CHEMICAL COMPOSITION OF DEPOSITED METAL (%):

C	Si	Mn	Cr	Ni	Mo
