PA-8018-G

AWS Specification: AWS A5.5 E8018G

JIS Specification : Z3241 DL5016-6AP1

Other Spcification: NONE

 

I. APPLICATIONS:

Welding of 55kgf/mm² class high tensile strength steel for ships, bridges, buildings, and boilers.

II. DESCRIPTIONS:

PA-8018-G is an iron powder low hydrogen type electrode, and provides good usability with direct current applications in all-positions. The weld metal has good crack resistability and X-ray soundness. Also it is suitable for multi-layer fillet welding in large leg length.

III. NOTES ON USAGE:

• Dry the electrodes at 300-350ºC for one hour before use.

• Take the backstep method or strike the arc on a small steel plate prepared to prevent blowholes at the arc starting.

• Keep the arc as short as possible.

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

C	Si	Mn	P	S	Ni
0.06	0.54	1.35	0.012	0.010	0.70

V. TYPICAL MECHANICAL PROPERTIES OF DEPOSITED METAL:
