ER5556 aluminum MIG welding wire
Author: Time:2023-05-17
ER5556 aluminum magnesium welding wire with higher than 5% mg and high manganese content, has high strength, good corrosion resistance and thermal cracking resistance. After the welding of the welding seam is still white, it can provide a good color for the welded joint.
Purpose: for high magnesium (3%Mg) aluminum alloy argon arc welding of filling material.

Note:
1. The welding wire is not used in the structure of aluminum alloy, which is more than 65 degrees, because in
the above mentioned temperature, the stress corrosion cracking of the welded joints.
the above mentioned temperature, the stress corrosion cracking of the welded joints.
2. Welding should be strict and clear the edge of the welding of the oxide film and oil, otherwise it will cause
welding seam welding and cause the hole, slag and other defects.
welding seam welding and cause the hole, slag and other defects.
3. Welding can be used for holding molten metal plate, in order to ensure the weld forming, and avoid hot crack.
