NIHONWELD N-CuAl-D
AWS Specification: ECuAl-D
JIS Specification:

NONE

Other Specification:

 

I. APPLICATIONS:

Higher yield strength and hardness than NIHONWELD N-CuAl-C.

     II. NOTES ON USAGE:

  • Keep the welding current as low as possible in the case of first-layer welding.

  • Preheating is not necessary in the case of lining of mild steels. The preheating temperatures varies in accordance with quality of base metal, a preheating temperature of 150 - 250ºC is required in general.

  • Preheat at 250ºC-300ºC is necessary in the case of welding brass.

  • The preheat temperatures varies in accordance with the preheat temperatures.

  • Keep the arc length as short as possible and don’t use too much weaving.
