tig welding 6061 aluminum filler rod

Name: tig welding 6061 aluminum filler rod
 
ER4043 aluminum silicon welding wire can be used as tig welding 6061 aluminum filler rod
Standard: GB/T10858 SAI4043 AWS A5.1 ER4043
Composition: Si=4.5-6.0%; Fe≤0.8%; Al balance.
 
Description:
ER4043 is a 5% silicon aluminum-silicon alloy welding wire, with a melting point of 573-625°C, good fluidity, strong thermal crack resistance, but insufficient ductility. Due to the high silicon content, when used for welding of high-magnesium alloys, brittle Mg2Si is easily formed in the weld, which reduces the plasticity and corrosion resistance of the joint. In addition, the color of the weld surface is dark, and the color of the base material is different after anodization.
 
Uses: Used as a filler for argon arc welding and gas welding of aluminum alloy workpieces and castings other than aluminum-magnesium alloys.
ER4043 aluminum silicon welding wire can be used as tig welding 6061 aluminum filler rod
Commonly used for welding 600 series aluminum alloys such as 6061, 3000 series and 2000 series aluminum alloys and cast aluminum. It is widely used in railway locomotive, chemical, food and other industries.
