FIG. 1 shows a CO provided in accordance with an embodiment of the present application2The implementation flow diagram of the welding control method is detailed as follows:
and step S101, detecting the working state of the welding machine.
Optionally, the method for detecting the working state of the welder comprises the following steps:
step a, obtaining the output current and the output voltage of the welding machine.
Optionally, the output current and the output voltage of the welding machine can be obtained through a current and voltage detection unit of the welding machine, when the welding machine is in short circuit transition, the short circuit state and the arc state are mutually alternated, and in the alternation process, the output current and the output voltage of the welding machine can be changed, so that the identification of the working state of the welding machine can be realized by monitoring the output current and the output voltage.
And b, if the output current of the welding machine is within a first preset current range and the output voltage of the welding machine is within a first preset voltage range, the working state of the welding machine is an arcing state.
Specifically, when the welder is switched from a short-circuit state to an arc state, the molten drop is separated from the end of the welding wire, the output current of the welder is reduced, the output voltage of the welder is increased, so that enough energy is released to melt the welding wire, the output current of the welder is in a first preset current range, and the output voltage of the welder is in a second preset voltage range.
And c, if the output current of the welding machine is within a second preset current range and the output voltage of the welding machine is within a second preset voltage range, the working state of the welding machine is in a short-circuit state.
Specifically, when the welding machine is switched from an arc state to a short-circuit state, the molten drop is in contact with the molten pool, the output current of the welding machine is increased, the output voltage of the welding machine is reduced, the output current is within a second preset current range, and the output voltage is within a second preset voltage range. For example, when the output current of the welder is detected to be larger than zero and the output voltage is detected to be smaller than 12V, the welder is determined to be in a short-circuit state.
Step S102, when the working state of the welding machine is detected to be converted into the arc state, the duration time of the arc state of the working state of the welding machine is obtained.
In the embodiment of the application, a timer can be selected for timing the welding machine in the arc state to obtain the duration, the starting point of the timer for timing the welding machine in the arc state is the moment when the molten drop is separated from the end of the welding wire, and the welding machine is switched from the short circuit state to the arc state at the moment. The timer keeps timing as long as the welding machine is always in an arc state.
Alternatively, the timer timing may be implemented by hardware circuitry or computer software.
And step S103, controlling the welding machine to reduce the output voltage and/or the output current under the condition that the duration time reaches the preset standard time and the working state of the welding machine is in an arc state.
In the embodiment of the application, the standard time is the time for forming the optimal volume of the molten drop, the molten drop can be stably transited to a molten pool at the moment, and splashing cannot be caused, namely the standard time is the optimal time for the transition of the molten drop, parameters of a welding wire used by a welding machine are different from parameters of shielding gas, and the standard time is also different, the corresponding relation among the parameters of the welding wire, the parameters of the shielding gas and the standard time can be obtained through experience or experiments, and after the parameters of the welding wire used by the welding machine and the parameters of the shielding gas are determined, the corresponding standard time can be determined.
The method for acquiring the standard time comprises the following steps:
and step A, acquiring current welding wire parameters and current shielding gas parameters of the welding machine.
Alternatively, the same welder can use welding wire with different parameters, which can include diameter, material composition, and stiffness, wherein both the diameter and the material composition of the welding wire can affect the formation of droplets during welding. The same welder can also use shielding gas with different parameters, and the shielding gas can be 100% CO2Or 80% Ar and 20% CO2The gas mixture, the shielding gas, can affect the formation of molten droplets during welding.
And step B, determining preset time corresponding to the current welding wire parameters and the current shielding gas parameters in the database as preset standard time.
Optionally, the database includes a plurality of sets of corresponding welding wire parameters, shielding gas parameters and standard time, wherein after the welding wire parameters and shielding gas parameters used by the welding machine are determined, the standard time can be determined, and when the time of the welding machine in an arc state is the standard time, the volume of the molten drop melted by the welding wire is the optimal volume, and at this time, the molten drop can be in stable transition to the molten pool without splashing.
When the welder is in short circuit transition, two states of a short circuit state and an arc state alternately appear. When the welding machine is in an arc state, molten drops are formed, and the volume of the molten drops is gradually increased along with the increase of time; when the welding machine is in a short circuit state, the molten drop is contacted with the molten pool, and the molten drop is transited to the molten pool to finish welding. The molten drop state can be monitored by acquiring the working state of the welding machine.
In the embodiment of the application, when the time that the welding machine is in an arc state reaches the standard time, the volume of the molten drop is the optimal volume of molten drop transition, and if the molten drop is in contact with a molten pool at the moment, the molten drop can be stably transited to the molten pool without splashing. However, when the time of the arc state of the welding machine reaches the standard time, the droplet cannot contact the molten pool and cannot be converted into the short-circuit state, the welding machine is still in the arc state, the volume of the droplet is continuously increased, as shown in fig. 2, the diagram is a relation diagram of output current and output voltage of the conventional welding machine during short-circuit transition, wherein Tb1, Tb2 and Tb3 are that the welding machine is in the arc state, and therefore, the time of the welding machine in the arc state is greatly different, and the longer the time of the arc state is, the larger the droplet is. Spatter can be caused when the welder is switched to a short circuit state, i.e., an excessively large volume of molten droplets is in contact with the weld puddle. And controlling the welder to reduce the output voltage and/or current, as shown in FIG. 3, for the welder at CO2The relation diagram of output current and output voltage during short circuit transition under the welding control method, wherein Ts is the arc state of the welding machine, and the diagram shows that the arc state time of each stage is basically the same, the volume of molten droplets is controlled, and the phenomenon of large droplet exclusion transition is prevented. The machine reduces the output voltage and/or current, reduces the speed of molten drop increase on the one hand, reduces the electric arc repulsion force of molten drop on the other hand, is favorable to the molten drop to hang down and contacts with the molten bath, prevents the splashing that the volume of molten drop too big caused.
In the short-circuit transition, the forces to which the droplet is subjected are the gravity of the molten metal, the surface tension of the liquid metal, the arc force and the plasma current force. Before the molten drop contacts with a molten pool, surface tension hinders the molten drop from being transited to the molten pool, the molten drop is favorably transited after the molten drop contacts with the molten pool, the surface tension is related to chemical components and temperature of the material, and the surface tension is reduced when the temperature is increased; the gravity of the molten drop promotes the molten drop to transit (flat welding position); the electric arc force has repulsion action on the molten drop transition, and the larger the current is, the stronger the repulsion action is; plasma flow forces are forces that promote droplet transfer. The transition of the welding droplet is thus a result of the above-mentioned four forces acting together.
In the embodiment of the application, under the condition that the duration reaches the standard time and the working state of the welding machine is in an arc state, the welding machine is controlled to increase the wire feeding speed.
When the duration time of the arc state of the welding machine reaches the preset standard time and the welding machine is still in the arc state, the welding machine can be controlled to increase the wire feeding speed in addition to the control of reducing the output voltage and/or current of the welding machine in the step S103. The feeding speed of the molten drop to the molten pool can be increased by increasing the wire feeding speed instantly when the melting speed is basically unchanged, and the short circuit transition of the molten drop can be accelerated.
CO as described above2Welding control method, CO2When the welding machine is used for welding at medium and high current, when the duration time of the welding machine in an arc state reaches the standard time, the volume of the molten drop is the optimal volume, the molten drop can be stably transited to a molten pool, and splashing cannot be caused. When the duration reaches the standard time, the welding machine is still in an arcing state, the volume of the molten drop can be continuously increased, and the large drop rejection transition is easily caused during the molten drop transition. At the moment, the welding machine is controlled to reduce the output voltage and/or the output current, so that on one hand, the speed of increasing the molten drop is reduced, on the other hand, the electric arc repulsive force of the molten drop is reduced, the molten drop is favorably hung and contacted with a molten pool, and the splashing caused by overlarge volume of the molten drop is prevented.
In an embodiment of the present application, prior to step S101, a database may be established, the database including a plurality of sets of corresponding wire parameters, shielding gas parameters, and standard times.
As shown in fig. 4, an implementation flow diagram of the database establishment method provided in an embodiment of the present application is detailed as follows:
step S401, obtaining a plurality of groups of corresponding welding wire parameters, shielding gas parameters and preset time.
Alternatively, the parameters of the welding wire may include diameter, material composition, and stiffness, among others, wherein both the diameter and the material composition of the welding wire can affect the formation of droplets during welding. The shielding gas parameters include composition, and shielding gases of different composition can affect the speed of droplet formation.
And S402, storing all groups of welding wire parameters, shielding gas parameters and preset time into a database.
Alternatively, the standard time may be obtained through a long welding experience, or through multiple tests.
For example, the standard times obtained by the test method are: the method comprises the steps of using a welding wire with a certain parameter and a protective gas with a certain parameter to carry out actual welding, observing the state of molten drops in the welding process (the observation of the state of the molten drops can be observed through an instrument or a manual work), timing when a welding machine is in an arc state, and observing the time when the molten drops form the optimal volume through multiple tests, namely standard time. When the volume of the molten drop is the optimal volume, the molten drop can be stably transited to a molten pool and does not splash, the optimal volume of the molten drop is not the determined volume and is a rough range, and the optimal volume of the molten drop can be determined according to experience. The standard time corresponding to a certain parameter of welding wire and a certain parameter of protective gas is obtained through the experimental method.
Through the steps S401 and S402, a database of corresponding relations among welding wire parameters, shielding gas parameters and standard time can be established, and after the parameters of the welding wire and the parameters of the shielding gas used by the welding machine are determined, the standard time can be determined, so that the control of the molten drop forming process in the welding process is realized.
In the embodiment of the present application, between step S102 and step S103 and after step S103, the method further includes:
and step M, controlling the welding machine to enter a short circuit control mode and resetting the timer under the condition that the working state of the welding machine is converted from an arc state to a short circuit state.
The short circuit control mode is a control mode of the traditional welding machine, and is not described in detail herein. When the welder is switched from the arc state to the short circuit state, the timer is controlled to be reset, so that the timer can count time again when the welder is switched from the short circuit state to the arc state.
CO as described above2Welding control method, during medium and large current welding, acquiring the work of welding machineAnd when the welder is switched to the arc state, controlling a timer to start timing to obtain the duration, and when the duration of the welder in the arc state reaches the standard time, the volume of the molten drop is the optimal volume, so that the molten drop can be stably transited to a molten pool and splashing can not be caused. However, if the welding machine is still in an arc state, the volume of the molten drop can be continuously increased, large drops are easy to reject and transition when the molten drop is in transition, and splashing is easy to generate. At the moment, the welding machine is controlled to reduce the output voltage and/or the output current, and the welding machine can also be controlled to increase the wire feeding speed of the welding wire. The feeding speed of the molten drop to the molten pool can be increased by increasing the wire feeding speed instantly when the melting speed is basically unchanged, and the short circuit transition of the molten drop can be accelerated. The reduction of the output current can reduce the melting speed of the welding wire, the reduction of the output voltage and the output current can also reduce the anode spot pressure on the molten metal at the end of the welding wire, which is beneficial to the molten metal at the end of the welding wire to form a drooping molten drop, and the reduction of the electric arc repulsive force and the drooping of the molten drop create favorable conditions for forming a short circuit.

and the detection module 51 is used for detecting the working state of the welding machine.
And the timing control module 52 is configured to, when detecting that the working state of the welding machine is converted into an arc state, obtain a duration that the working state of the welding machine is in the arc state.
And the welding machine control module 53 is used for controlling the welding machine to reduce the output voltage and/or the output current under the condition that the duration time reaches the preset standard time and the working state of the welding machine is in an arc state.
When the welder is used for welding with medium and large currents, the detection module 51 detects the working state of the welder, when the welder is switched to the arc state, the timing control module 52 obtains the duration time of the welder in the arc state, and when the duration time of the welder in the arc state reaches the standard time, the volume of molten drops is the optimal volume, so that stable transition can be carried out to a molten pool, and splashing cannot be caused. However, if the welding machine is still in an arc state, the volume of the molten drop can be continuously increased, large drops are easy to reject and transition when the molten drop is in transition, and splashing is easy to generate. At this time, the welding machine control module 53 controls the welding machine to reduce the output voltage and/or the output current, so that on one hand, the speed of increasing the molten drop is reduced, on the other hand, the electric arc repulsive force of the molten drop is reduced, the molten drop is favorably sagged to be contacted with a molten pool, and the splashing caused by overlarge volume of the molten drop is prevented.
