Controlled environment chamber for use in cladding a nonaluminum core with aluminum

A method of cladding a nonaluminum core with at least one aluminum cladding strip by preheating both the core rod and the strip with the former being preheated to about 1000 DEG F. to 1300 DEG F. and the latter being heated to about 600 DEG F. to 1000 DEG F. Cleaning the core rod and the strip and p...

Zusammenfassung:	A method of cladding a nonaluminum core with at least one aluminum cladding strip by preheating both the core rod and the strip with the former being preheated to about 1000 DEG F. to 1300 DEG F. and the latter being heated to about 600 DEG F. to 1000 DEG F. Cleaning the core rod and the strip and passing them through a controlled environment chamber containing a reducing or neutral gas. Lubricating the bonding roll grooves to provide a substantially continuous coating of lubricant thereon. Galling of the aluminum strip or strips to the bonding rolls is resisted as a result of this process.
