PA-8016-B2

AWS Specification: AWS A5.5 E8016-B2

JIS Specification: DT2316

Other Specification: DIN ECrMo1B26

I. APPLICATIONS:

Welding of 1.25% Cr-0.5% Mo steel used for super heater tube, steam pipes and headers of boilers for electric power plant and equipment for oil refining industry.

II. DESCRIPTIONS:

PA-8016-B2 is a low hydrogen type electrode for all-position welding, which provides the weld metal 1.25% Cr-0.5% Mo.

III. NOTES ON USAGE:

• Dry the electrodes at 325-375ºC for about one hour before use.

• Preheat at 150-300ºC and postheat at 670-730ºC.

1. 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.
