PA-8018-C3
AWS Specification: AWS A5.5 E8018-C3
JIS Specification: NONE
Other Specification: NONE
I. APPLICATIONS:
Cor-ten, Mayari R, LT75, N-A-Z High Tensile, V-55, Yoloy HS, military and commercial applications.
II. DESCRIPTIONS:
PA-8018-C3 is a 1% nickel, low hydrogen, iron powder electrode used for welding high strength steels in the 70-80,000 psi tensile strength range. This electrode offers high deposition efficiency, producing excellent quality of weld weld deposits with good impact properties even at temperatures as low as -60°C. PA-8018-C3 is also used for fillet welds on high strength quenched and tempered steels such as ASTM A514 and A517. PA-8018-C3 may be used in any position with AC or DC (reverse polarity).
III. NOTES ON USAGE:
-
Dry the electrodes at 350-400°C for about one hour before use and store the electrodes at 100-150°C after drying them with attention to keep away from moisture.
-
Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose, because arc striking on base metal is in danger of initiating cracking.
-
Keep the arc as short as possible.
-
Preheat at 100-150°C. The temperature to be applied varies in accordance with plate thickness and kind of steel to be welded.
-
Pay attention not to exceed proper heat-input because excessive heat-input causes deterioration of impact values and yield strength of weld metal.
