PHiLARC - The No. 1 Choice of Welders

PA-10016-G

AWS Specification: AWS A5.5 E10016-G

JIS Specification : Z3212 D8016

Other Spcification: NONE

 

I. APPLICATIONS:

Welding of 80kgf/mm2 class high tensile steel for pressure vessels, penstocks, bridges, offshore constructions, and industrial machinery and construction machinery.

II. DESCRIPTIONS:

PA-10016G is a low hydrogen type electrode for all-position welding and provide good X-ray soundness, notch toughness and crack resistibility.

III. NOTES ON USAGE:

  • Dry the electrodes at 350ºC-400ºC for about one hour before use. Store the electrodes at 100-150ºC after drying, keeping them 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 120-180ºC. 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.

  • Immediate post heating at 150-200ºC after welding is effective to prevent cracking.
