Specific embodiment
Fig. 1 is referred to, is the flow chart of the gas shielded arc welding striking control method of one embodiment of the invention.As shown in the figure,
A kind of gas shielded arc welding striking control method, including step S100 settings preset time t, initial wire feed rate VeWith target wire feed
Speed Vs。
Step S200, according to preset time t, initial wire feed rate Ve, target wire feed rate VsAnd wire types, it calculates
The interior filler wire energy Q risen to wire feed rate from initial wire feed rate Ve needed for target wire feed rate Vs of preset time t.
Step S300 determines the default duty ratio W of pulse signal according to required energy Q and welding machine type.Due to difference
Welding machine characteristic it is different, such as output power, output voltage, electric current etc., therefore preset duty ratio is also different.
Step S400 starts arc welding gun switch, and output pulse signal driving IGBT, the duty ratio of the wherein pulse signal is pre-
If duty ratio W.
Step S500 after welding wire touches workpiece, keeps the default duty ratio W in preset time t.Namely in wire feed speed
Degree is increased to target wire feed rate VsBefore, preset duty ratio is all maintained to export.
Step S600, after welding output current is detected, control wire feed rate is in preset time t from initial wire feed speed
Spend VeRise to target wire feed rate Vs.Namely since detect welding output current after start after just adjustment wire feed rate,
Wire feed rate is improved to avoid too early, causes wire feed too fast.
Such gas shielded arc welding striking control method, according to the required energy of welding wire in fusing preset time, meter
The duty ratio of pulse needed for calculation rises to target wire feed rate so as to finely control wire feed rate from initial wire feed rate, obtains
Metastable arc shape during the starting the arc, it is ensured that electric arc can once ignite, and effectively increase starting the arc efficiency.
It is the time diagram of the gas shielded arc welding striking control method of one embodiment of the invention incorporated by reference to Fig. 2.As schemed
Show, in t1Time starts arc welding gun switch, starting switch signal (a), and starts output pulse signal (b), which accounts for
Sky is than to preset duty ratio W.Then in t2Time welding wire touches workpiece, and the duty of pulse signal is kept in preset time t
Than for W.Simultaneously in t2After time detects welding output current (c), start to control wire feed rate (d) from initial wire feed rate Ve
Rise, until t3Reach target wire feed rate V during the times.In the present embodiment, when welding wire touches workpiece, that is, welding is detected
Output current namely t2When detect welding output current.It is understood that in other examples, due to welding machine
With the contact condition of workpiece, current detecting is it is possible that delay.So detecting the time of electric current can also be prolonged accordingly
Afterwards.Equally in the present embodiment, preset time t is equal to and reaches target wire feed rate VsTime t3With start to detect that welding is defeated
Go out the time t of electric current2Between time difference.In other examples, due in order to ensure the wire feed rate in preset time t
It can complete from initial wire feed rate VeIt is increased to target wire feed rate Vs, some times, therefore the preset time t can be reserved
It can be slightly longer than and reach target wire feed rate VsTime and starting detect time difference between the time of welding output current.
That is, preset time t is more than the wire feed rate rise time, the wherein wire feed rate rise time is fast from initial wire feed for wire feed rate
Spend VeRise to target wire feed rate VsTime.It is more than pulse letter after preset time to maintain default duty ratio in pulse signal
Number it is restored to duty ratio during normal weld, it is generally the case that can in due course be adjusted according to feedback current, generally have a standing wave
It is dynamic.
Further, Fig. 3 is referred to, is the sub-step stream of the gas shielded arc welding striking control method of one embodiment of the invention
Cheng Tu.As shown in the figure, step S210 is further included in step s 200 according to preset time t, initial wire feed rate Ve, target wire feed
Speed VsAnd wire types, calculate the wire feed length L in preset time t.Wherein, initial wire feed rate VeIt can be even with straight line
Speed is increased to target wire feed rate Vs.Can also be that (PID adjustings) mode is adjusted from initial wire feed speed by proportional integral differential
Spend VeRise to target wire feed rate Vs.In the present embodiment, Fig. 2 is referred to, is exactly normal with certain wire feed rate adjusting ratio
Number KpIntegral constant K is adjusted with wire feed rateiBy PID regulative modes from initial wire feed rate VeRise to target wire feed rate
Vs.Wherein proportionality constant KpWith integral constant KiIt is determined according to the characteristic of wire-feed motor.To simplify the calculation, in the present embodiment, it is micro-
Divide constant KdWith saturation constant KcCan be zero.Such wire feed rate control, it is more stable and smooth, it can effectively ensure that
Arc efficiency and quality.
Step S220 is further included in step S200 according to needed for the welding wire that wire feed length L calculates fusing wire feed length L
Energy Q.Preferably, Q=Hm×L×πr2(1), wherein HmFor the proportionality coefficient set according to wire types, r is the half of welding wire
Diameter.Wherein, proportionality coefficient Hm, it is to be set according to the fusing point of welding wire, it is however generally that proportionality coefficient HmIt is directly proportional with the fusing point of welding wire
Example relationship.That is, the fusing point of welding wire is higher, proportionality coefficient HmBigger, the fusing point of welding wire is lower, proportionality coefficient HmIt is smaller.
Further, further included in step S300 the efficiency eta according to welding machine, welding machine DC bus-bar voltage UiAnd weldering
The output current I of machineaDefault duty ratio W is calculated.Since the energy Q needed for fusing wire feed length L divided by efficiency eta are equal to
The energy namely U that preset time t internal welding machine is exportedi×Ia× W/100 × t=Q/ η (2), so as to calculate default account for
Empty ratio：
With reference to formula (1) and (3), default duty ratio can be obtained：
Wherein, HmFor the proportionality coefficient set according to wire types, t is preset time, and L is that the wire feed in preset time is long
Degree, radiuses of the r for welding wire, UiFor the DC bus-bar voltage of welding machine, IaFor the output current of welding machine, η is the efficiency of welding machine.
In this way, according to the type of welding wire and the type of welding machine, default duty ratio W can be accurately calculated, so as to
It is precisely controlled wire feed rate.
