Welding electrodes Monolith E4047

AWS/ASME A5.3: E4047

EN ISO 18273: Al 4047 (AlSi12)

product.uv

Clean the welding area of dirt and oxide film. Preheat heavy parts. When joining thick metal to thin part, preheat the heavier part
Weld at high current with a short arc, ensuring rapid electrode advance. Reduce current during welding and as the base metal absorbs heat

product.sv

The coating, formed by the pressing method, provides a long service life and increased resistance to moisture

Aluminum-silicon electrodes intended for welding cast, rolled and extruded aluminum and aluminum-based alloys with a flint content of up to 12%, such as Al-Si Al-Mg, Al-Mg-Si, Al-Mn-Cu.
