Description
Technical field
The invention belongs to welding technique fields, and in particular to a kind of titanium alloy welding locality protection tool and its welding
Method.
Background technique
Nuclear power plant turbine blade shroud (titanium alloy) gap is exceeded to be mainly inserted into properly in gap in the prior art
Titanium sheet, adjust gap after weld, since titanium and its alloy chemistry are active, in welding process be easy it is miscellaneous by oxygen, hydrogen, nitrogen etc.
The pollution of matter, and then Weld Performance is made to be deteriorated, welding process and postwelding are the weights for determining weldquality to the protection of welding region
Want factor.
Thickness uses argon tungsten-arc welding in 3mm titanium or titanium alloy welding below at present, is divided into open type welding and case
Weld two types.Open type welding belongs to a kind of local gas protection welding method i.e. under atmospheric environment.It is welded in case and is
Test specimen is placed in cabinet or operating room, is first vacuumized before weldering, then the protective gas such as applying argon gas, belongs to whole gas and protects
Shield.
Open type protection is suitable for structure and simply welds, and using dragging cover to carry out, implementation is more convenient, but protecting effect one
As.Cabinet protection, needs vacuum chamber, and complicated operation, and being applicable in also has certain limitation.According to the reality of titanium inserted sheet
Specification, when carrying out qualification of welding procedure work, both the above welding region protected mode is all not easy to welding procedure.Cause
This needs to set to solve the protection problem of above-mentioned welding region during steam turbine titanium alloy inserted sheet qualification of welding procedure
A kind of titanium alloy welding locality protection tool is counted, to solve the above technical problems.
Summary of the invention
Object of the present invention is to provide in view of the above shortcomings of the prior art a kind of titanium alloy welding locality protection tool and its
Welding method, for solution, auxiliary welding personnel is more in the prior art, welding is complicated for operation, and operational instrument, which is applicable in, has limitation
The technical issues of.
The technical scheme is that
A kind of titanium alloy welding locality protection tool, comprising: protective shell, hanging basket, gas averaging board and pellet；Hanging basket suspension is being protected
Inside protective case, gas averaging board is arranged between protective shell and hanging basket；Pellet is arranged inside hanging basket, pellet lower end and gas averaging board upper end
It is threadedly coupled.
Protective shell as described above is integrally in hollow cylindrical structure, and protective shell base portion is equipped with air flue, air flue and protective shell
Inside is together with protection gas enters from the air flue.
Pellet as described above is integrally in solid cylinder structure, and pellet lower end is provided with cylindrical type boss, boss outer surface
Equipped with screw thread.
Hanging basket as described above is integrally in hollow cylindrical structure, and hanging basket upper end is provided with annular convex platform, is protected for hanging on
Inside protective case；The hanging basket is uniformly distributed on peripheries with several through-holes.
Hanging basket bottom center as described above is additionally provided with tapped through hole.
Gas averaging board surface as described above is evenly equipped with several ventholes, and gas averaging board upper end is additionally provided with thread groove, and screw thread is recessed
Slot internal diameter matches with pellet lower end cylindrical type boss size；Thread groove outer diameter and hanging basket bottom thread through-hole ruler
It is very little to match.
A kind of welding method of any titanium alloy welding locality protection tool as described above, includes the following steps:
Step 1: titanium inserted sheet procedure qualification test block is placed on to the welding region of pellet upper end；
Step 2: after filling a period of time protective gas by protective shell bottom air flue, protective gas passes through hanging basket and gas
Plate is persistently covered on around entire welding piece, after having completely cut off air, then starts welding.
Step 3: it after the completion of welding, persistently fills protection gas and is dropped under specific temperature until being soldered test specimen weld seam.
The invention has the following advantages:
The present invention develops applicable specific purpose tool according to the actual size of titanium alloy inserted sheet, what the present invention designed
Tool is by special design structure and selects suitable material, and control protective gas is entirely welded with lasting current stabilization state coverage
Test specimen completely cuts off air, and reduces rapidly welding piece temperature, although guaranteeing that test specimen still can achieve satisfied guarantor in open environment
Protect effect.
If carrying out same procedure qualification, according to open type support cover guard method, outfit welder one is generally required, is born
The specific implementation of welding is blamed, is responsible for tracking for auxiliary work one and fills protective gas.The specific purpose tool designed using the present invention only needs one
Whole work can be completed in welder, and operate more simple.Compared with vacuum chamber in the prior art, present invention design is not required to
Vaccum-pumping equipment works for subsequent titanium inserted sheet qualification of welding procedure, and present invention design is more effective simple.
