ALUMINUM METAL-CORE WELD WIRE AND METHOD FOR FORMING THE SAME

摘要

Disclosed is an aluminum metal-core weld wire for producing aluminum we ld deposits, the weld wire comprising a sheath and a core, the sheath being aluminum or aluminum alloy and the core containing a composition which includes metal or metal alloy powders. The method for manufacturing the aluminum metal-core wire includes depositing a core composition onto a strip of aluminum, forming the strip of aluminum into a tube which contains the core composition, applying an inorganic lubricant to the surface of the tube, and drawing the tube through a plurality of reducing dies. The invention also comprehends the aluminum tube useful in forming an aluminum metal-core wire.
