Description
Technical field
The present invention relates to diesel pressure booster repair welding technical field, especially a kind of diesel engine of locomotive booster nozzle ring swashs
Light repair welding device and its repair welding method.
Background technique
HXn5 type diesel engine of locomotive booster critical component whole import, price is high, the period is long, nozzle ring therein according to
Domestic locomotive pressure device inspection code, allow crack number must not exceed 2, length must not exceed 5mm, and actual conditions are
With extending with the time, the crackle that root of blade occurs also is greatly increased, it is specified that repairing the nozzle ring almost all crackle in journey
It transfinites, such as all replacement is all great cost pressure to our company and client, while being also the great wasting of resources, it is therefore desirable to
Restorative procedure appropriate is selected, realizes nozzle ring repairing and reusing.
The nozzle ring is whole centrifugal casting molding, and blade windward side is thick and solid and air outlet is frivolous, and central transition section is
The curved surface of gradient thickness, to realize wind-guiding and release effect, while both ends of the blade connects thick and solid inside and outside wall again to ensure entirety
Intensity, cause the variation of blade air outlet root thickness greatly, pressure-bearing greatly, be easy to appear crackle, and crackle can outside pars intramuralis prolong
It stretches.The material composition of the nozzle ring has iron, manganese, cobalt, tungsten, niobium, chromium, nickel, belongs to high temperature resistant iron-nickel alloy, and when reparation needs higher
Temperature could melt, and blade air outlet less than the thickness of 1.5mm require repair when calorific value must it is small, otherwise will appear heat
Crackle, in this regard, common argon arc welding even micro- arc welding cannot all be met the requirements.
And it is domestic at present many using the patent and report of laser melting and coating process progress part reparation, such as: Publication No.

Weld seam checks that no crackle then repairs completion through penetrant inspection.
By taking blade air outlet root crack at one as an example, the repair welding method of this repair welding device is as follows: the process first step is out
Welding groove: checking nozzle ring 4, finds out all blade air outlet root cracks, is carried out with standard caliper to crackle
Label, then cut, polish, all crackles are made into the groove of unified specification, blade stays bevel edge, outer wall to stay straight flange；Process second
Step is light beam positioning: the scroll chuck 3 of nozzle ring 4 being fixed on two-way deflection machine 2, adjusting two-way 2 angle of deflection machine makes to spray
The tilting suitable position of mouth ring 4, then the position of laser melting coating head 5 is adjusted, guiding light beam is located in 4 blade openings of nozzle ring
On, so that it is determined that the X of laser melting coating head 5, Y-axis orientation, the Z axis orientation of laser melting coating head 5 are determined by height block, at this time laser
Cladding head 5 goes out light orientation straight down, angled with blade openings, and weld seam can be made sufficiently to merge with outer wall；Process
Three steps are laser melting coatings: padding upper profile-followed copper billet in blade openings bottom, it is ensured that copper billet is firm, which presses between blade
Shape is prepared, and powder can both have been reduced below opening by, which padding, is lost the shape it is also ensured that weld seam bottom, starts welding procedure,
Laser melting coating head 5 first go out protection gas, again powder feeding, finally go out light, linear robot 6 simultaneously by preset program move, make metal powder
End merges with the material of blade, outer wall in the molten bath that blade, outer wall and copper billet are formed, solidifies one layer of weld seam of formation, passes through conjunction
Suitable powder feed rate, laser power, robot movement speed, it can be ensured that weld seam has enough thickness that blade openings are welded completely
Full, after molten bath is filled up, program ends automatically out light, powder feeding, supplies gas, and laser melting coating head 5 returns in situ standby；The 4th step of process is
Repeat soldering: two-way deflection machine 2 turns an angle, and next place's blade openings is made to be moved to current location, repeats process third
Step completes soldering, and then repetitive operation is until the opening soldering of all blade cracks is completed；The 5th step of process is weld seam correction of the flank shape and inspection
It looks into: polishing weld seam, comply with blade original shape but slightly protrude, local fillet is more bigger than original, better to guarantee
Bonding strength.Weld seam after correction of the flank shape checks that no crackle then repairs completion through penetrant inspection.If blade air outlet crack growth
Into outer wall, the polishing of circular shape is carried out to outer wall in the process first step, forming one completely removes crackle root,
On the basis of four steps, according to third step in one layer of weld seam of angle heap of weld seam and outer wall, the part of outer wall missing is filled up,
It repeats the 4th step trimming weld seam and detects a flaw.Program Solidification is convenient for operation, it may be necessary to the entire nozzle ring of continuous automatic welding
All blades, and the thermal deformation welded is small, weld seam is secured, intensity increases, and the nozzle ring after reparation meets the use of booster
It is required that.
Described above to be merely exemplary for the purpose of the present invention, and not restrictive, those of ordinary skill in the art understand,
In the case where not departing from spirit and scope as defined in the appended claims, many modifications, variation or equivalent can be made, but all
It will fall within the scope of protection of the present invention.
