PA-9018-B3
AWS Specification : AWS A5.5 E 9018-B3
JIS Specification : JIS Z3223 DT 2418
Other Specification: DIN 8575 ECrMo 2 B 26
I. APPLICATIONS:
PA-9018-B3 is used in piping steels (A335-P22), boiler and heat excharger steel tubes (A199-T22, A200-T22, A213-T22), rolled steels (A387-D), cast steels (A217-WC) and forged steels (A182-F22, 336-F22).
II. DESCRIPTIONS:
PA-9018-B3 is an all position, iron powder-low hydrogen electrode developed for welding 2.25% Cr-1% Mo steel which is subjected to elevated temperatures such as those found in the power piping and boiler industries. This electrode has extremely high deposition efficiency, producing X-ray quality weld deposits with mechanical properties that meet or exceed AWS-ASTM requirements. PA-9018-B3 electrodes yield a stable arc with low spatter. AC or DC (reverse polarity) may be used.
III. NOTES ON USAGE:
-
Dry the electrodes at 325-375ºC for about one hour before use.
-
Preheat at 200-350ºC and postheat at 680-730ºC.
-
Adopt back step method or strike the arc on a small steel plate prepared for this particular purpose to prevent blowholes at the arc starting.
-
Keep the arc as short as possible.
