AWS A5.10: ER4043 EN ISO 18273: S AL 4043 (ALSi5)

The aluminum welding rods ER4043 are used for argon-arc welding of casting aluminum-silicon Al-Si alloys of AD31, AD33, AD35 types (ICE blocks, support plates, frames, etc.) with direct current in the argon environment as an adding material. They are used in all the industrial processing fields such as automobile industry, automotive equipment production, shipbuilding, etc.

 

APPLICATION CONDITIONS

Welding should be done on AC, or on devices that support pulse-arc mode. Protective gas: Ar (argon), Ar / He mixture (argon / helium). Weld surfaces should be cleaned of oxide film and degreased. The products, welded with ER4043 filler rods, are not subject to further anodization, since the resulting color of the base and the weld metal is different. 

SPECIAL PROPERTIES

The filler rods ER4043 are used for welding Al-Si-Cu cast alloys with other aluminum alloys. The high silicon content provides good weldability of the edges, allowing to get a smooth transition from the weld to the base metal and a smooth shiny surface. At the same time, the deposited metal has excellent corrosion resistance and is not prone to hot cracking and stress corrosion cracking under operating temperatures above 65 °C.
