AWS A5.10 ER4043 Solid wire
TEMO ER4043, GB/T 10858 SAl 4043
Description:
ER4043 is an Al-Si alloy welding wire can use where base metal require thermal treatment, mainly 6xxx series alloys. Higher silicon improve fluidity, make it become preferred choices of welders. This product is not sensitive to weld crack, it also can be used on weld forge and casting materials.
Diameters: Packaging:
0.8mm-4.0mm 0.5kg, 1kg, 2kg 5kg 7kg
Applications:
Mainly used for welding 6XXX alloys, and most casting alloys, automotive components such as frame and drive shafts.

Notes:
1. Before welding, impurities such as rust, oil stains, and moisture must be removed from the welded parts.
2. Shielded gas: 100%Ar or 75%Ar+25%He or 50%Ar+50%He.
3. In order to get good welding bead, weld on thick plate should be preheat 100-200℃ before welding.
