Short circuiting transfer refers to welding rod (or welding wire), and molten drop and the molten bath shorted contacts of end, due to strong overheated and magnetic
Contraction, makes molten drop quick-fried disconnected, directly to the mode of metal transfer of molten bath transition.This form is used primarily in-melt pole electrical arc
In weldering.
In short circuit transition, after arc burning, heat, filler wire are separated out by electric arc, and is gathered in welding wire termination few
Amount droplet metal.Arc space is formed as welding wire melts rapidly, and its length is decided by arc voltage.Subsequently, droplet volume
Gradually increase, and arc length slightly shortens.As molten drop is constantly grown up, electric arc subtracts to the incoming heat in unfused welding wire direction
Few, then welding wire melting rate is also reduced.As welding wire is still sent into certain speed, so it is molten that molten drop certainly will be caused to move closer to
Pond, arc length are shortened.Molten drop and molten bath all in constantly undulatory motion simultaneously, this adds increased the machine that molten drop is contacted with molten bath
Meeting.Every just to make arc space short circuit, then arc extinction when contacting, arc voltage drastically declines, close to zero, and it is short-circuit
Electric current starts increase, forms liquid metals post between welding wire and molten bath.The fluid column of this state can not be voluntarily disrumpent feelings.With short circuit
Exponentially rule constantly increases electric current, and the electromagnetic contractile force caused by it consumingly compresses fluid column, while in surface tension
Under effect so that fluid column metal flows to molten bath, and necking down is formed, the necking down is referred to as " foot bridge ".This foot bridge is connected to welding wire
With molten bath, while by larger short circuit current, and foot bridge is made due to excessively thermal evaporation and explode rapidly.At this moment arc voltage is quickly
More than floating voltage is returned to, electric arc is ignited again.Subsequently constantly repeat said process.
In short circuit transition, arc stage is replaced with short-circuit stage and is changed.At the end of short-circuit stage, it is always accompanied by light
Light explosion sound and a small amount of splatter.During arc stage, arc length is shorter, and during short-circuit stage between welding wire and molten bath always
It is connected to by liquid metal.
During short circuit, because the effect of return cable resistance and inductance, as long as the rate of change of electric current is sufficiently large, measure
Voltage will be very high, if judging whether to be possible to send out into arcing state by the weldingvoltage of measurement welding terminal
Raw erroneous judgement.The disclosure passes through the resistance in measuring system return cable before welding and inductance value, then in welding process,
The weldingvoltage and welding current of collection welding terminal, the weldingvoltage contain the electric resistance partial pressure on cable and inductance pressure
Drop, can be calculated arc voltage by resistance and inductance value, and with this judging the generation moment of arcing.
A kind of arcing condition judgement method is provide firstly in this example embodiment, be can apply to electric arc welding and is set
Standby, such as Fig. 1, the arcing condition judgement method can include：
In step slo, obtain the resistance value and inductance value in return cable.

Pressure value.
In step s 30, according to the resistance value, the inductance value, the welding current value and the welding voltage value
Obtain arc voltage.
In step s 40, judge the arc voltage whether more than predetermined threshold.
Wherein, when the arc voltage is more than the predetermined threshold, decision-making system enters arcing state.
The arcing condition judgement method of the disclosure, device and arc-welding equipment, are returned by measuring system before welding
Resistance and inductance value on the cable of road, then in welding process, gathers the voltage and current value of welding terminal, the voltage bag
Contain the electric resistance partial pressure and inductive drop in return cable, arc voltage can be calculated by aforesaid resistance and inductance value,
And with this judging the generation moment of arcing such that it is able to it is inherently eliminated the welding terminal that electric current acute variation is brought
Impact of the voltage glitch to arcing condition adjudgement, makes the judgement of arcing state more accurate.

Road electric current I ', and short-circuit voltage U ' now is detected according to the voltage detection unit, according to the short circuit current I ' and institute
Resistance value R that short-circuit voltage U ' is calculated return cable is stated, specific formula for calculation is as follows：
R=U '/I '
In one embodiment, according to welding machine output fixing rate of change dI " the electric current I that is changed ", voltage U " calculate
Inductance, according to U "=I " * R+L*dI " it is calculated L.Wherein dI " is unit time current rate of change, shown in equation below：
L=(U "-I " * R)/dI "
In disclosure example embodiment, as shown in Fig. 2 resistance value R and inductance value L that obtain in return cable can be with

Wherein, current changing rate dI can ask first order derivative to obtain time t for current value I.
In step s 320, inductive drop value Ul is determined according to the current changing rate dI and inductance value L.
For example, it is as follows according to inductive drop value Ul computing formula：
Ul=L dI
Resistive voltage value Ur is determined in step S330, according to welding current value I and resistance value R.
For example, the computing formula of resistive voltage value Ur is as follows：
Ur=I R
It should be noted that the execution of above-mentioned steps S320 and step S330 does not have sequencing, both can be simultaneously
Perform, or first carry out step S330, then execution step S320, the disclosure is not construed as limiting to this.
In step S340, according to the welding voltage value U0, resistive voltage value Ur and inductive drop value Ul
Determine the arc voltage Ua.
For example, the circuit connection diagram with reference to shown in Fig. 4, is said so that the arc-welding equipment is as welding machine as an example
Bright, the computing formula of arc voltage Ua is as follows：
Ua=U0-Ur-Ul=U0- (I R+L dI)
In step s 40, judge the arc voltage Ua whether more than predetermined threshold.
When the arc voltage Ua is more than the predetermined threshold, decision-making system enters arcing state.The predetermined threshold
Can specifically be set according to system requirements, the disclosure is not construed as limiting to this.
In disclosure example embodiment, methods described also includes：When the arc voltage Ua is less than or equal to described pre-
When determining threshold value, decision-making system is in short-circuit condition.
Shown in the weldingvoltage U0 of the outfan of one exemplary welding machine of the detection with reference to shown in Fig. 5, fire in prior art
Arc decision method is susceptible to erroneous judgement at the A moment, although the weldingvoltage U0 at A moment is likely larger than predetermined threshold, but in fact
And it is introduced into arcing state.According to the arcing decision method of the disclosure, the resistance and electricity on measuring system loop before welding
Inductance value, then in welding process, gathers weldingvoltage U0 and welding current I, and the weldingvoltage contains the resistance on cable
Partial pressure and inductive drop, can be calculated arc voltage Ua by resistance and inductance value, and with this judging during the generation of arcing
Carve.As seen from Figure 5, arc voltage Ua can be inherently eliminated the hair of the weldingvoltage U0 that electric current acute variation is brought
Thorn, makes the judgement of arcing more accurate.
