It should be noted that the present embodiment welding system can be used for manual, semi-automatic and robot welding operation.Cause
This, the present embodiment can be used for widely welding operation.
Fig. 2 (a) is exemplary three holes ignition tip schematic diagram in the present embodiment, and there are three independent outlets for the ignition tip
Hole, respectively first outlet hole 21, second outlet hole 22 and third outlet opening 23；Throwing of the center of circle of three outlet openings on base material
Shadow is three vertex of equilateral triangle, and the distance between two hole centers of circle are L, such as Fig. 2 (b).
Angle when welding wire leaves outlet opening, between the first welding wire, the second welding wire and third welding wire and ignition tip center line
It is all satisfied within the scope of ± 10 °.
It one in front and one in back arranges compared to mariages and the welding manner of twin wire parallel power arrangement is easy to cause weld width inconsistent,
Three outlet openings of the present embodiment form the layout of equilateral triangle, it can be ensured that in welding process, welding wire and electricity in welding direction
The variation that arc arrangement occurs is minimum, it is ensured that weld width, fusion penetration are always consistent, and three deposition efficiencies are higher, weldering
It connects more efficient.
Distance L is selected to that a molten drop and transition, also, three welding wires can be merged into after ensuring wire tip fusing
End ensures to be not attached to together.In the present embodiment, distance L is that biggish in the diameter of three welding wire A1/A2/A3 that is straight
In the range of 1.2~3.5 times of diameter.For example, distance L can be if each of welding wire is all with the diameter of 1mm
In the range of 1.2~3.5mm.In addition, distance L can be in maximum gage of wire in manual or semi-automatic welding operations
In the range of 1.2 times to 2.5 times, however in robot welding operation, distance L can be 2.4 times in maximum gage of wire
To in the range of 3.5 times.In the exemplary embodiment, distance L is in the range of 1.2mm to 2.5mm.By experimental verification,
When distance L is within the scope of 1.2-1.5mm, welding effect is very good, and as distance L is smaller, fusion penetration increases, and weld width is smaller,
The adjustable range of fusion penetration and weld width can be increased；In the embodiment of the present invention, when distance L is 1.2mm, weld penetration is reachable
1.2 times of fusion penetration when being equal to 2.5mm to L, weld width reduction 15%, meanwhile, welding arc size becomes smaller, and reduces undercut and lacks
Sunken generation.
Fig. 3 (a) depicts the current mobility direction of welding wire A1, A2 and A3 in the present embodiment and the electromagnetism distribution of generation.
Welding current passes through each corresponding welding wire by separated after ignition tip, when using identical diameter and the welding wire of type, weldering
Connecing electric current will be split evenly between by welding wire.When using different-diameter and the welding wire of type, welding wire resistance value is different, accordingly
Electric current will be assigned due to the relationship of V=I*R.Due to the flowing of electric current, magnetic field R is generated around welding wire.Fig. 3 (b) is this
Embodiment welding wire distribution of electromagnetic force generates the tightening force being pulled towards each other, resultant force suffered by A1, A2 and A3 welding wire between two welding wires
It is directed toward the central point of the equilateral triangle of three root wires formation.This magnetic force is intended to generate molten drop between three welding wires.Fig. 3
(c) be the present embodiment molten drop schematic diagram, welding wire under the action of electromagnetism tightening force, between two welding wire centers of wire tip away from
From L will be less than, but not contact with each other.As the electric current for passing through each of welding wire melts the end of welding wire, electromagnetic force
It is intended to for the molten drop of melting to be pulled towards each other until they are connected to each other, merges into transition after a molten drop.
Fig. 4 (a) is droplet transfer process schematic, and wherein molten drop bridge joint generates, and constantly grows up, finally in gravity, table
Molten bath is transitioned under face tension and electromagnetic force, wherein electromagnetic force is used to bind round disconnected molten drop on molten drop bridge joint.
Fig. 4 (b) is another embodiment droplet transfer schematic diagram, and L is sufficiently small at this time, can choose welding wire maximum gauge
1.2~1.5 times；When wire tip forms molten drop, welding wire does not contact with each other, but liquid droplets are in electromagnetic force
Under, it is extruded between three welding wires, at this point, also achievable stable transient process.Therefore, it compared to double wire welding mode, adopts
Three wire bond welding systems being laid out with the present embodiment equilateral triangle will lead to weld penetration increasing with the reduction of distance between weldingwires L
Greatly, weld width reduces, and this patent can further decrease the spacing L of welding wire, increase the adjusting model of weld width and fusion penetration
It encloses.
Fig. 5 depicts the two different example waveforms that can be used for the present embodiment.In general, electric current increase is molten to generate
Drop, molten drop are gradually grown up, then the gravity, electromagnetic force the effects of under be transitioned into molten bath.In the present embodiment, transition molten drop is average
1.2~1.5 times close to spacing L of diameter.
Fig. 5 (a) is the exemplary output current wave signal that the present embodiment pulsed sprays welds types operation, is had
Then background current 51, the background current transit to peak current level 52.During this period, molten drop is formed and is gradually grown up,
Under the action of duration of peak value, the droplet transfer to molten bath.After the transition happens, when repeating this process, then electric current declines again
To base value level.For example, peak point current can be maintained at 550A~650A by some embodiments, background current be maintained at 300A~
In the range of 400A, and time to peak is the range of 6ms-10ms.In such embodiment, welding deposition effect can be significantly improved
Rate, for example, such embodiment deposition efficiency is up to 10Kg/h~16Kg/h, and the deposition rate of single welding wire process is in 4.5Kg/h
Within the scope of~7.5Kg/h, double wire welding technique deposition rate is in 8.6Kg/h~11.79Kg/h.
Fig. 5 (b) is another exemplary welding current waveform schematic diagram in the present embodiment, and control mode is Isobarically Control,
Since welding current is big, molten drop and molten bath are without short circuit in welding process, and electric current is equally without fluctuation.Molten drop is being higher than spray transfer
Under the function of current, a molten drop was merged into before this, was then transitioned into molten bath.Under such Current Waveform Control, the droplet transfer is same
Sample is uniform.For example, some embodiments make electric current be maintained at 500A~700A, voltage is maintained within the scope of 40V~42V, is melted at this time
Drop transition frequency is 80~150Hz.
Fig. 6 (a) is using the single welding wire of tradition in exemplary cut deal weld seam and the schematic diagram of welding process, due to monofilament
Technique deposition rate is limited, causes single track welding welding bead degree of seeing not reach requirement, needs to solve by multilayer multiple tracks, welding efficiency
It is lower.And the monofilament technique under the conditions of big deposition rate is easy to appear finger-like fusion penetration (B spot size width is too small), finger-like fusion penetration
Occur, is easy to cause stomata welding defect (in welding process, gas has little time to overflow molten bath and formed), causes under weld strength
Drop.
The present embodiment can alleviate thick plates problem among the above, can improve welding while improving welding quality
Efficiency.Fig. 6 (b) is the present embodiment cut deal weld seam and welding process schematic diagram.The present embodiment may be implemented similar or improve
Weld size, make weld seam depths have broader welding bead, improve fusion penetration shape, reduce finger-like fusion penetration, reduce weld porosity lack
It falls into.And deposition efficiency is improved, multi-layer multi-pass welding is not required to.
