N-CuSn-A

Specification

AWS Specification: AWS A5.6 ECuSn-A
JIS Specification: N/A
Other Specification: N/A

Description

Application

Remarks

  • Preheating and interpass temperature are required; for phosphor bronze and gun metal: 150 - 200ºC; for brass: 250 - 300ºC
  • Do not use too much weaving
  • The bead width should be kept within 3x 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 improving 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.
