Laser titanium alloy blisk blades molding manufacturing process

The present invention pertains to a titanium alloy material and manufacturing technical field, particularly a laser disc blade integrally formed titanium alloy blade manufacturing process. The present invention, through a coaxial powder feeding laser cladding method, forming the titanium alloy is deposited directly on the blade hub bosses forging titanium alloy previously machined edge, compared to the prior art, without a mold having a small machining allowance, low cost, short cycle, highly flexible, easy to operate, forming quality advantages. A process according to the present invention proposed, in order cladding layer only in each boss to be a layer that, according to this method allows the cladding in order after all the lap end bosses Cladding depositing cladding layers have sufficient time to cool, the edge collapse effectively solve the problem, and the synchronization of each blade increases also eliminates the possibility of laser cladding head with the blade is brought into contact and collision has been formed.
