Електроди зварювальні Monolith E 4047

ISO 18273: Al 4047 (AlSi12)
AWS/ASME A5.3: E4047
CONDITIONS OF USE
  • Clean the welding area from dirt and oxide film. Preheat heavy parts. When connecting a thick metal with a thin part, preheat the heavier part. Welding should be carried out with high current on a short arc, ensuring rapid advance of the electrode. Reduce the amperage during the welding process and as the base metal absorbs heat.
SPECIAL PROPERTIES
  • The coating, formed by the pressing method, ensures a long service life and increased resistance to moisture.
Aluminium-silicon electrodes with a silicon content of 12%. Universal electrodes for welding cast, rolled and stamped aluminum and aluminum alloys. Designed for welding aluminum and alloys based on the type: Al-Si, Al-Mg-Si, Al-Cu-Mg, Al-Zn-Mg. Typical uses: loading ramps and loading platforms, window and door frames, gearbox housings, engine cylinder blocks, electrical busbars, electrical switch boxes and mounting supports.
