Description
Aluminum and aluminum alloy welding wire is selected according to
the base material type, mechanical properties, and corrosion resistance requirements of the welded joint.
Typically, for welding aluminum and aluminum alloys, thin sheets
with similar chemical compositions to the base metal are cut into
strips and used as welding wires.
For heat-treated aluminum alloys with a high tendency to hot cracking, welding wires with excellent crack resistance are preferred to ensure weld integrity and mechanical performance.
