N-CuSnC (DC)

Specification

AWS Specification: AWS A5.6 ECuSn-C
JIS Specification: N/A
Other Specification: DIN 1733: S-Cu Sn 7

Description

Application

Remarks

  • Clean parent metal of rust, paint, seals, oil, grease, and moisture to ensure porosity free welds
  • Because copper has high heat conductivity, preheating and interpass temperature are required for heavy sections (5mm & more)
  • For phosphor bronze and gun metal: 150 ? 200ºC
  • For brass: 250 ? 300ºC
  • No preheating is required sections that are less than 5.0mm on ferrous based materials
  • 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 for 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.
