NIHONWELD N-CuSn-A
AWS Specification: ECuSn-A
JIS Specification:

NONE

Other Specification:

 I. APPLICATIONS:

For joining and surfacing of copper-alloys, phosphor and tin bronzes. Deposit is sea water resistant. Current AC or DC+.

II. DESCRIPTION:

Deposit is sea water resistance. Good weldability and arc stability guarantee a porosity-free deposit.

III. NOTES ON USAGE:

  • Preheating and interpass temperature are required.

     For phosphor bronze and gun metal  150~200ºC

     For brass 250~300ºC

  • Don’t use too much weaving. The bead width should be kept within 3 times of rod diameter.

  • Apply hot peening on every bead because the structure of deposited metal is rough at as welded condition. Hot peening is effective to improvement of mechanical properties.

Typical data and Test results for mechanical properties, deposit or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards, and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.
