1)Profile welded combination
Different specifications of several profiles are designed by welded through the friction stir welding, and machined block body structure for carriage.


2)Friction stir welding
Using a special type of stirring head to move with rotating , to generate heat by the friction between the stirring head and the workpiece. The friction heat makes this part of metal in the thermoplastic state, and the welding part is connected to a whole by the pressure of the agitator.

Chalco Aluminum has the Aluminium alloy profile and welded combination profile for heavy-duty freight train,with the alloy 6005 ,6005A,6061,6082 and temper T4,T5,T6.
