Combustion chamber throat carry out argon arc welding re melting process and formed, aditus laryngis metallographic structure is obtained the mechanical property that refinement improves aluminium alloy
Can, meet engine calls；Cooling velocity reaches the several of casting conventional chilling speed during combustion chamber throat argon arc welding re melting process
Ten times, aluminium alloy micostructure is changed into very tiny block primary silicon, point-like Eutectic Silicon in Al-Si Cast Alloys and tiny metallographic structure, uniform point
Dissipate in the matrix of AL, the mechanical property of aluminium alloy is greatly improved；Argon arc welding aditus laryngis remelting region carries out finishing after being formed
Work treatment.
Operation principle of the present utility model is：The utility model provides a kind of argon arc welding remelting piston, and structure is novel；Set
Argon arc welding aditus laryngis remelting region；Remelting is carried out to piston aditus laryngis using argon arc welding, combustion chamber throat is obtained local strengthening, remelting
Process stabilization, changes small to the piston technological process of production, and cost is more economical.
The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, in the ken that one skilled in the relevant art possesses, can also be on the premise of this patent objective not be departed from
Make a variety of changes.
