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

The aluminum welding wire 4043 (AK5) is used for argon-arc welding of casting aluminum-silicon alloys of AD31, AD33, AD35 types (ICE blocks, support plates, frames, etc.) with direct current in the argon environment as an adding material. It is used in all the industrial processing fields such as automobile industry, automotive equipment production, shipbuilding, etc.

APPLICATION CONDITIONS

The goods for which the welding wire ER4043 has been used are not subject to further anodizing due to the difference of the received colors on the main and weld metal. It is not recommended for welding goods of aluminum alloys with a thickness of more than 20 mm. If the thickness is 10 mm and more the heating of up to 150-200 C is required to reduce the possibility of porosity. Protective gas: 11 (Ar 100%), 13 (Ar+5…95% He).

Precision layers winding provides uniformity and stability during the feeding.

 

SPECIAL PROPERTIES

The welding wire ER4043 is used for welding of Al-Si-Cu casting alloys with other aluminum alloys. The high content of silicon provides good edge welding, forming a smooth transition from the joint to the main metal and smooth shiny surface. Besides, the weld material has an excellent corrosion resistance, not apt to formation of hot cracks and corrosion cracking under voltage at the operating temperature over 65°С. 

Precision layers winding essentially increases the operation period of semi-automatic welders.
