With reference to Fig. 2, in the first moment T1, wire feed rate uniform descent by initial wire feed rate V0, until second
Moment T2 drops to brake speed Vz.By wire feed rate function it can be concluded that be normal function the first acceleration function, and by with
Lower formula indicates wire feed rate function V and the first acceleration function f:
V (T)=f*T+b (1)
F=a (2)
Wherein, a, b are constant, and those skilled in the art can self-setting according to the actual situation.

For exemplary, when gage of wire is greater than preset value, it can be controlled by virtual wire feed rate function and virtually be sent
Silk speed changes from slow to fast.Bigger energy, matching are exported in the welding current of control for the previous period that wire feed rate starts variation
Relative virtual wire feed rate can avoid electricity compared with slow practical wire feed rate (heat input is big, wire feed is slow) with the thick welding wire of rapid melting
The problems such as arc is short, splashing increases, appearance of weld is bad avoids crin haircuts, effectively promotes the welding efficiency of thick welding wire.
Opposite, when gage of wire is less than preset value, it can control virtual wire feed rate and change from fast to slow.In wire feed
The welding current of control for the previous period that speed starts variation exports smaller energy, and matching relative virtual wire feed rate is practical faster
Wire feed rate (heat input is small, wire feed is fast), effectively avoiding flashing back, stage electric arc is too long, caused electric arc is unstable, flashes back length too
Long the problems such as even burner influences striking again in turn.
The above-mentioned preset value for judging welding wire thickness can self-setting according to the actual situation, the disclosure not as
Limit.
Fig. 3 is a kind of method for determining virtual wire feed function in the embodiment of the present disclosure.

The functional value of function increases over time, and absolute value reduces.
In order to determine the expression formula of virtual wire feed rate function W, in addition to the enlightenment of the virtual wire feed rate function process of determination
Except the form of speed point A (T1, V0), stopping speed point B (T2, Vz) and the second acceleration function g, it is also necessary to determine virtual
The vertex position C (T3, V3) of wire feed rate function W.
Parameter or system recommendation parameter can be specified to determine the abscissa T3 of vertex position C according to user first, i.e., second
At the time of the functional value of acceleration function is equal with the functional value of the first acceleration function.Then, it is determined according to gage of wire D
The length of d line segment in T3 time chart 4C and Fig. 4 D is with the difference of the functional value of determination virtual wire feed rate function W and wire feed function V
Absolute value m, and then determine vertex C ordinate V3.In the process, h can be true according to default monotonically increasing function h (D)
It is fixed, i.e. m=h (D).Those skilled in the art can voluntarily Tuning function h (D) form and parameter, the disclosure do not make this
Particular determination.
In this way, meeting following formula when the second acceleration function is linear function:
W '=g=α T+ β (3)
G (T3)=a (4)
W (T1)=V (T1)=V0 (5)
W (T2)=V (T2)=Vz (6)
W (T3)=V (T3)+h (D) (7)
Wherein, α, β are constant, and a, V (T), T1, V0, T2, Vz can be obtained according to wire feed rate function V, T3, D, h
(D) it is manually entered, selected or system detects automatically, recommends by user.COMPREHENSIVE CALCULATING formula (3)~(7), it is available virtually to send
The expression formula of silk velocity function W.
It is the calculating process in an embodiment of the present disclosure above, when the second acceleration function is not linear function, this
Field technical staff can also determine virtual wire feed rate according to the form and parameter of the second acceleration function of self-setting
The expression formula of function W.
In another embodiment of the disclosure, virtual wire feed rate may be following formula:
Wherein, W is virtual wire feed rate, Vz、V0Respectively according to the determining brake speed of the wire feed rate function and just
Beginning wire feed rate, n are control parameter update times, and k (d) is adjustment parameter related with the gage of wire d, the adjustment parameter
Including but not limited to continuous function, discrete function.Such as adjustment parameter be discrete function, k (d1)=k1, k (d2)=k2 etc.,
Middle d1, d2 are default gage of wire, and k1, k2 are the corresponding k values of above-mentioned default gage of wire.It can receive user a variety of default
The setting signal of selection is carried out in gage of wire, and then k value is determined according to corresponding relationship.
Fig. 5 A and Fig. 5 B are the schematic diagrames of virtual wire feed function in another embodiment of the disclosure.
With reference to Fig. 5 A and Fig. 5 B, value of the slope of virtual wire feed function in addition to can be consecutive variations can also be discrete
Value.At this point it is possible to obtain the preset of the virtual wire feed rate function process (in Fig. 5 A and Fig. 5 B according to the gage of wire
D, E point), the virtual wire feed rate function is determined according to the preset.
Preset can also both be pushed away by system according to gage of wire generation by user setting or by system default
It recommends value and user is allowed to modify recommendation.In addition, the embodiment of the present disclosure does not limit the quantity and coordinate of preset.
It in step S106, responds arc welding gun switch and unclamps signal, the wire feed rate is controlled according to the wire feed rate function,
Simultaneously according to the welding parameter of the virtual wire feed rate function control welding current.
When gage of wire is greater than preset value, virtual wire feed rate is greater than practical wire feed rate, according to virtual wire feed rate
The welding current energy of output can burn-off rate slower thick welding wire in time, avoid that electric arc is too short, the problems such as increasing of splashing, can
To adjust for crin to height of preferably flashing back.
When gage of wire is less than preset value, virtual wire feed rate is less than practical wire feed rate, according to virtual wire feed rate
When the faster thin welding wire of the welding current energy burn-off rate of output, the problems such as can too long to avoid electric arc, even burning ignition tip,
It can be adjusted for thin diameter wire to height of preferably flashing back.
By above method, can effectively solve crin flash back stage energy it is too low caused by the stage electric arc that flashes back it is too short,
Caused spatter increases even haircuts, and the filament electric arc caused by energy height that flashes back is too long, causes stomata, incomplete fusion, undercut,
Etc. the bad problem of welding qualities, effectively improve welding quality and welding efficiency.
