PA-8016-C3

AWS Specification: AWS A5.5 E8016-C3

JIS Specification: NONE

Other Specification: NONE

 

I. APPLICATIONS:

Low hydrogen for low temperature welding of line pipes in the field.

II. DESCRIPTIONS:

PA-8016-C3 is a nickel-alloyed electrode designed for the welding of 1%Ni steel or high tensile steel with impact requirements down to -45°C. In addition to its good welding performance in all position, this electrode contains 1%Ni in the weld metal to obtain the qualified impact value and good X-ray performance and usability.

III. NOTES ON USAGE:

• Pay attention not to exceed proper heat-input because excessive heat-input causes deterioration of impact values and yield strength of weld metal.

• Preheat at  50-100°C at the postheat at 600-620°C. The preheat temperature varies in accordance with the plate thickness and kind of steels.

• Dry the electrodes at 350-400°C for about one hour before use

• 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.
