The preset voltage that electric current matches is unified voltage.Wherein, the electric current rate of rise in pulse period T, pulse period T is
K1, descending slope K2, crest voltage U1, peak point current I1, the average voltage in a pulse period are U'.
Referring to shown in Fig. 3, before welding, need according to the suitable expert of the selections such as welding material, welding wire, used gas
Data adjust suitable Current Voltage for plate thickness on this basis.Assuming that preset current is I' in expert data, it is matching
Voltage is unified voltage U, pulse period T.As preset voltage Ur ≠ U, the arc length of electric arc is elongated, is needed at this time according to preset
Departure between voltage Ur and unified voltage U will be adjusted to T1 normal period, specifically,Its
In, K is constant.
After preset voltage and preset current determine, in the welding process, if stem elongation is elongated, then the arc length of electric arc
Also can be elongated, on the contrary it can shorten.Actual welding situation is complicated and changeable, and when some technique requires stem elongation variation, arc length can
It remains unchanged, since welding personnel can recognize arc length, and in pulse welding process, usually by crest voltage
Determine arc length, if therefore welding personnel need to remain unchanged arc length, it is constant to can control crest voltage.Crest voltage master
It to be influenced by peak point current and time to peak, the average voltage of pulse period is also the one of arc length in the whole welding process
A important references amount.
During climbing due to connecing the stage in the striking stage to main weldering, pulse parameter is being constantly updated, it will usually be generated
The problem of being fired on electric arc, propose for this problem, in the embodiment of the present invention the real-time detection pulse period average voltage U,
The average value U1 of average current I, crest voltage are calculated when the average value U1 of crest voltage U1' and crest voltage generates deviation
The change rate of crest voltageWith the deviation of electric current
Then peak point current I1, rate of rise K1, descending slope K2 and pulse period are adjusted by K_u and K_i,
It is specific as shown in figure 4, wherein each value adjusted are as follows:
Peak point current adjusted: I2=K_i × K_u × I1；
The rate of rise adjusted: K3=K_i × K_u × K1；
Descending slope adjusted: K4=K_i × K_u × K2；
Pulse period adjusted: T1=K_i × K_u × T.
During the welding process, if the preset voltage of gas metal-arc welding is also changed, to the pulse period
It is adjusted again, the pulse period adjusted: T2=K_u × T1.
Control can be adjusted to the parameters of gas metal-arc welding in the technical solution of the above embodiment of the present invention
System, improves the stability of gas metal-arc welding, it is ensured that gas metal-arc welding has good welding effect.
