Description
Technical field
The present invention relates to be used to carry out the arc-welding apparatus after the improvement that gas shielded arc welding connects.
Background technology
In the gas shielded arc welding of consumable electrode formula or non-melt electric pole type connects, need shield atmosphere to protective gas such as electric arc and molten bath ejection carbon dioxide, argon gas, prevent in the atmosphere intrusion welding atmosphere.The flow-control of protective gas is very important in certain permissible range.Under the less situation of gas flow, thereby become unstable, therefore produce bubble, or produce sputter in a large number because atmosphere is invaded the state of electric arc in the welding atmosphere.Otherwise under the too much situation of gas flow,,, or produce insufficient (incomplete) penetration etc. so the protection that becomes sometimes is bad because produce turbulent flow.Its result, the outward appearance of weld seam worsens sometimes, and failure welding becomes.
In the general arc-welding apparatus that comes the opening/closing protective gas with magnetic valve, when opening magnetic valve, in the needed processing of supplying gas in advance, the protective gas of excessive flow is ejected when promptly beginning to weld.This phenomenon is expressed as prominent stream below.Prominent stream is according to piping length, pressure, since elapsed time that gas is closed last time etc., and its peak flow is different with the duration, therefore sprays after the protective gas, and the time till flow-control is in permissible range is also different.An example below is described.In addition, above-mentioned since elapsed time that gas is closed last time be to be illustrated under the situation about existing continuously between a plurality of weld zones, the elapsed time that the output of the protective gas since between the last time weld zone stops.
Fig. 5 is the figure of sample attitude that is used to illustrate the prominent stream of protective gas.The figure shows making that to set flow be under 15 liters/minute the situation, according to the elapsed time that gas was closed since last time be several seconds, and gas flow along with the time through how to change.Changes in flow rate when this figure (a) expression was 4 seconds since elapsed time that gas is closed last time.Equally, this figure (b) expression 3 seconds, this figure (c) expression 2 seconds, this figure (d) expression 1 second, the changes in flow rate of this figure (e) expression in the time of 0.5 second.As shown in the drawing, the time soon after opening magnetic valve, thereby owing to the gas of the superfluous flow of prominent stream is ejected, along with the process of time, near the setting flow of stipulating with the gas flow setting apparatus (being 15 liters/minute in the figure).If hypothesis in advance the time of supplying gas be configured to 0.5 second, then for example in this figure (a), under the state of having exported about 42 liters/minute protective gas, carry out striking and handle, therefore might produce above-mentioned this failure welding.
Be used to suppress to weld the technology of beginning prominent stream partly, in patent documentation 1 and 2, be disclosed.In patent documentation 1, disclosing series connection two magnetic valves and the arc-welding apparatus of opening/closing (below, be called conventional art 1) simultaneously have been set.In addition, in patent documentation 2, the welder (below, be called conventional art 2) of the gas flow control module that possesses machinery such as throttle orifice is disclosed.According to conventional art 1 and 2, suppress prominent stream by using mechanical means, played the generation that can prevent failure welding, and the effect that also can save the consumption of protective gas.
On the other hand, not only need to suppress to weld the prominent stream of beginning part, and the gas flow in the arc welding need be maintained only flow.As illustrated in fig. 5, gas flow is after the prominent stream convergence of welding beginning part, near the setting flow of stipulating with the gas flow adjuster and become fixing.If on the gas flow of appropriateness, become fixing, then can not cause failure welding.Yet for example, under the situation that arc-welding apparatus such as using arc welding robot welds, a general workpiece has a plurality of welding positions, and according to the welding position difference, and different situation such as groove shape, welding, thickness of slab is also a lot.In this case, preferably change the setting flow of protective gas according to each welding position.For example, generally compare, under the situation of fillet weld in the flat position, even it is also no problem to reduce the setting flow of protective gas mostly with the situation that groove is shaped as the angle overlap weld seam.Yet, because gas flow is the fixed amount with gas flow adjuster regulation, so the situation that exists the gas flow in the arc welding under the more state of former state maintenance, to be used.In the case, the possibility that has protective gas to be wasted.
The technology that is used for solving this problem is disclosed at patent documentation 3.In patent documentation 3, disclose a kind of service property (quality) flow (mass flow) controller and dynamically controlled the gas processing plant of gas flow (below, be called conventional art 3).In general, mass flow controller can change the setting of gas flow from the outside, control by built-in gas flow detector and gas flow regulator, so that actual gas flow becomes the gas flow of setting, and also can carry out the output of gas and stop with the mass flow controller monomer.According to conventional art 3, by dynamically controlling gas flow, can keep optimum flow, and can save the consumption of protective gas.
As mentioned above, in conventional art 1 and 2,, can't dynamically change gas flow, therefore the gas flow in the arc welding can't be adjusted into optimum value though can suppress to weld the prominent stream of beginning part.On the other hand, in conventional art 3,, can either suppress to weld the prominent stream of beginning part, the gas flow in the arc welding can be adjusted into optimum value again by the service property (quality) flow controller.But, but have problem described later.

Fig. 6 is the figure of the changes in flow rate of the protective gas in the expression conventional art.This figure (a) is the sequential chart of gas control signal, opens from closing to become on moment t1.This figure (b) is with the result behind the gas control signal opening/closing, is the figure how the expression gas flow changes along with the process of time.In this figure (b), the waveform when waveform Ha represents only to carry out the control of protective gas with a magnetic valve, waveform Hb represents the mass flow controller by above-mentioned conventional art 3, the waveform when gas flow is under control.
In conventional art 3, shown in waveform Hb, moment t1 during the t2 (about about 1 second.Below, be called and set flow time of advent.) in, gas flow is increased gradually and reach the setting flow.Mass flow controller before the gas flow that makes reality reaches the setting flow, has suppressed prominent stream by the cost certain hour.
If begun welding in the time of advent, then because of the gas flow of need not guaranteeing, so might be owing to the bad weld defect that produces of protection at above-mentioned setting flow.There is following problem: needed gas flow during in order to ensure the welding beginning, need to wait for that gas flow reaches the setting flow, therefore become the delay reason of cycle time.Though also having above-mentioned setting flow is high performance mass flow controller about 0.3 second the time of advent, so exist because the unusual high price problem that is difficult to import.
