Technical Field

Background

The gas metal arc welding equipment uses the electric arc generated between the meltable welding wire and the weldment as the heat source, and feeds the shielding gas to the welding area through the nozzle, and can continuously feed the welding wire. The equipment ignites electric arcs generated between the welding wires and a weldment in a mode of electrifying the welding wires, so that the welding wires are melted after reaching a melting point, and the purpose of welding is achieved.

The arc striking performance of the gas metal arc welding equipment is related to the welding quality of the initial position of a welding seam, and the arc striking performance of the welding equipment is influenced by the temperature state of a welding wire during welding. The arc striking energy required by the welding wire in different temperature states in the welding process is different, for example, when the temperature of the welding wire is higher, less arc striking energy is required to reach a melting point; when the temperature of the welding wire is lower, more arc striking energy is needed to reach the melting point, wherein the arc striking energy is related to welding parameters such as arc striking current, arc striking voltage, arc striking duration and the like, and the best welding quality can be achieved only if the arc striking energy is provided to be suitable for the temperature state of the welding wire. However, the welding parameters of the conventional gas metal arc welding equipment are generally fixed values, namely, the arc striking energy provided by the equipment for the welding process is also fixed, and the temperature state of the welding wire is changed, so that the arc striking energy provided by the equipment cannot be dynamically adjusted according to the temperature state of the welding wire, and therefore the fixed welding parameters restrict the arc striking performance of the gas metal arc welding equipment, and the improvement of the welding quality is restricted.

Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.

Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.

Example one

Fig. 1 is a flowchart of a welding parameter determination method according to an embodiment of the present disclosure, which may be applied to a scenario in which a welding parameter needs to be adjusted and determined according to a temperature state of a welding wire. The method may be performed by a welding parameter determination apparatus provided in an embodiment of the present application, which may be implemented by software and/or hardware, and may be integrated in an electronic device, which may be a welding device.

As shown in fig. 1, the welding parameter determination method provided in the embodiment of the present application may include the following steps:

s110, if a welding trigger signal is detected, determining a welding wire temperature characteristic quantity according to a weighting coefficient, arc striking current at the end of last welding and a time interval from the end of last welding to the detection of the welding trigger signal; wherein the weighting coefficient is determined according to the size of the welding wire.

The execution body of the present embodiment may be a welding apparatus, such as a gas metal arc welding apparatus. In this embodiment, the detection of the welding trigger signal may be that the user presses a switch of the welding device to start the welding device, and the welding device detects a key operation of the user. The arc striking current at the last welding end refers to the current value provided by the power supply of the equipment at the last welding end, and it can be understood that the welding equipment is electrified by the power supply to the welding wire, and the welding wire is melted by utilizing the heat generated by igniting the arc between the welding wire and a weldment to achieve the purpose of welding.

The characteristic quantity of the welding wire temperature is related to the temperature state of the welding wire, and the characteristic quantity of the welding wire temperature is inversely proportional to the arc striking current at the end of the last welding and is directly proportional to the time interval from the end of the last welding to the detection of the welding trigger signal.

In this embodiment, optionally, the wire temperature characteristic quantity is determined according to the following formula:

K＝Kd*T/I；

wherein K is a welding wire temperature characterization quantity, Kd is a weighting coefficient, T is a time interval from the end of the last welding to the detection of a welding trigger signal, and I is an arc striking current at the end of the last welding.

It will be appreciated that the longer the time interval between the end of the last weld and the detection of the weld trigger signal, the greater the wire temperature indicator. Because the longer the time interval, the longer the time interval between restarting the device and using, the welding wire temperature at this time is lower, need more energy to make the welding wire reach the melting point. The greater the wire temperature indicator, the greater the value of the welding parameter, such as the arc initiation current, can be adjusted to provide more energy to the welding process. Conversely, if the time interval is shorter, the wire temperature indicator is smaller. Because the time interval is short, the equipment is restarted to weld again shortly after the last welding, and the temperature of the welding wire is high, so that much energy is not needed for enabling the welding wire to reach the melting point. The smaller the temperature characteristic quantity of the welding wire is, the smaller the value of the welding parameter such as arc striking current can be adjusted, so that less energy is provided for the welding process, and the energy consumption is saved. The same principle is used for the relation between the arc striking current and the welding temperature characterization quantity at the last welding end.

In the present embodiment, the wire size may be a wire diameter, a wire length, and the like. Fig. 2 is a schematic diagram showing the relationship between the weighting coefficient Kd and the wire diameter according to the present embodiment, and as shown in fig. 2, the weighting coefficient Kd is proportional to the wire diameter.

According to the method and the device, the temperature state of the welding wire is expressed according to the arc striking current when the last welding is finished, the time interval from the last welding to the detection of the welding trigger signal and the weighting coefficient, the welding parameters can be flexibly adjusted, equipment reasonably provides arc striking energy for the welding process, and the problems that the welding is not firm due to insufficient energy supply or resources are wasted due to excessive energy supply are avoided.

And S120, determining a target adjustment coefficient of the welding parameter according to the welding wire temperature characteristic quantity and the adjustment weight.

The welding parameters are variable quantities that affect the welding result during welding with the welding equipment.

In this embodiment, optionally, the welding parameter includes at least one of an arc initiation current parameter, an arc initiation current duration, an arc initiation voltage parameter, and an arc initiation voltage duration.

Further, in this embodiment, optionally, if the welding parameter is arc striking current and/or arc striking voltage, the adjustment weight is a first adjustment weight, and if the welding parameter is arc striking current duration and/or arc striking voltage duration, the adjustment weight is a second adjustment weight, where the first adjustment weight is greater than the second adjustment weight.

In this embodiment, the target adjustment coefficient is used to adjust the reference value of the welding parameter. It is understood that the reference value of the welding parameter is determined according to the welding equipment, and the reference value of the welding parameter is different for different welding equipment.

For example, the target adjustment coefficient may be expressed by the following formula:

K1K, or Kt 2K

Wherein Ka and Kt are both target adjustment coefficients, K is a welding wire temperature characteristic quantity, K1 is a first adjustment weight, and K2 is a second adjustment weight. When the welding parameters needing to be adjusted are arc striking current and/or arc striking voltage, the target adjustment coefficient of the welding parameters is Ka; when the welding parameter to be adjusted is the duration of arc-starting current and/or the duration of arc-starting voltage, the target adjustment coefficient of the welding parameter is Kt.

Further, K1 is greater than K2. It is understood that the magnitude of the adjustments for the arc initiation current and the arc initiation voltage in this embodiment is greater than the arc initiation current duration or the arc initiation voltage duration.

According to the technical scheme, the arc striking current parameter, the arc striking current duration, the arc striking voltage parameter and the arc striking voltage duration are used as welding parameters needing to be adjusted, reasonable arc striking energy can be directly provided for an arc striking process, and therefore a welding result can reach a more ideal state. In addition, different adjustment coefficients are set, and the adjustment coefficients of the arc striking current and the arc striking voltage are larger than the adjustment coefficients of the arc striking current duration and the arc striking voltage duration, so that the time cost can be reduced as much as possible, and more reasonable arc striking energy is provided for the arc striking process through the arc striking current and the arc striking voltage.

And S130, adjusting the reference value of the welding parameter according to the target adjustment coefficient to obtain a target welding parameter, and welding according to the target welding parameter.

The reference value of the welding parameter is adjusted according to the target coefficient to obtain the target welding parameter, and the target coefficient can be applied to the reference value of the welding parameter according to a certain rule to obtain the target welding parameter. Furthermore, the certain rule may be one of an addition, subtraction, multiplication and division algorithm or a combination of several algorithms, which is not limited in this embodiment.

The embodiment realizes the adjustment and determination of the welding parameters by the following method: if the welding trigger signal is detected, determining a welding wire temperature characteristic quantity according to the weighting coefficient, the arc striking current at the end of the last welding and the time interval from the end of the last welding to the detection of the welding trigger signal; wherein the weighting coefficient is determined according to the size of the welding wire; determining a target adjustment coefficient of a welding parameter according to the welding wire temperature characteristic quantity and the adjustment weight; and adjusting the reference value of the welding parameter according to the target adjustment coefficient to obtain a target welding parameter, and welding according to the target welding parameter. Utilize welding wire temperature token to express welding wire temperature state among the above-mentioned technical scheme to adjust welding parameter according to welding wire temperature token, and then make equipment arc striking energy and the welding wire temperature state phase-match that the welding process provided, avoided the welding wire temperature lower and the arc striking energy is less to lead to the welding wire not to reach the melting point, thereby influence welding quality, can avoid the welding wire temperature higher and the energy waste that the arc striking energy is great leads to again, can also the energy saving when guaranteeing the firm degree of welding.

Example two

Fig. 3 is a flowchart of a welding parameter determination method according to a second embodiment of the present application, which is optimized based on the second embodiment. The concrete optimization is as follows: determining an adjustment coefficient of a welding parameter according to the welding wire temperature characteristic quantity and the adjustment weight, wherein the adjustment coefficient comprises the following steps: determining an initial adjustment coefficient of welding parameters according to the welding wire temperature characterization quantity and the adjustment weight; and determining a target adjustment coefficient according to the relationship among the initial adjustment coefficient, the maximum adjustment coefficient and the minimum adjustment coefficient.

As shown in fig. 3, the welding parameter determination method provided in the embodiment of the present application may include the following steps:

s210, if the welding trigger signal is detected, determining the temperature characteristic quantity of the welding wire according to the weighting coefficient, the arc striking current at the last welding end and the time interval from the last welding end to the detection of the welding trigger signal.

And S220, determining an initial adjustment coefficient of the welding parameter according to the welding wire temperature characteristic quantity and the adjustment weight.

And S230, determining a target adjustment coefficient according to the relationship among the initial adjustment coefficient, the maximum adjustment coefficient and the minimum adjustment coefficient.

The minimum adjustment coefficient and the maximum adjustment coefficient may be determined according to experimental data, and the minimum adjustment coefficient and the maximum adjustment coefficient are related to performance of the device, and the minimum adjustment coefficient and the maximum adjustment coefficient may be different for different devices.

In this embodiment, optionally, determining the target adjustment coefficient according to the relationship between the initial adjustment coefficient and the maximum adjustment coefficient and the minimum adjustment coefficient includes: if the initial adjustment coefficient is smaller than the minimum adjustment coefficient, taking the minimum adjustment coefficient as a target adjustment coefficient; if the initial adjustment coefficient is greater than or equal to the minimum adjustment coefficient and less than the maximum adjustment coefficient, taking the initial adjustment coefficient as a target adjustment coefficient; and if the initial adjustment coefficient is greater than or equal to the maximum adjustment coefficient, taking the maximum adjustment coefficient as a target adjustment coefficient.

For example, let Kamin and Kamax be the minimum and maximum adjustment coefficients of arc striking current and arc striking voltage, Ka be the initial adjustment coefficients of arc striking current and arc striking voltage, Ktmin and Ktmax be the minimum and maximum adjustment coefficients of arc striking current duration time and arc striking voltage duration time, and Kt be the initial adjustment coefficients of arc striking current duration time and arc striking voltage duration time. If Kamin is less than Ka and less than Kamax, taking Ka as a target adjustment coefficient of arc striking current and arc striking voltage; if Ka is less than Kamin, taking Kamin as a target adjustment coefficient of arc striking current and arc striking voltage; if Ka > Kamax, then Kamax is used as the target adjustment coefficient of arc-striking current and voltage. The determination of the target adjustment coefficients of the duration time of the arc-striking current and the duration time of the arc-striking voltage is performed in the same manner as above.

In the embodiment, the initial adjustment coefficient is compared with the minimum and maximum adjustment coefficients to obtain the target adjustment coefficient, so that the target adjustment coefficient is a reasonable value, and the problem that the adjusted welding parameter is too large and the equipment cannot provide too large energy due to too large or too small target adjustment coefficient caused by errors, or the adjusted welding parameter is too small and the energy provided by the equipment is insufficient, so that the set welding effect cannot be achieved is solved.

And S240, adjusting the reference value of the welding parameter according to the target adjustment coefficient to obtain a target welding parameter, and welding according to the target welding parameter.

In this embodiment, optionally, adjusting the reference value of the welding parameter according to the target adjustment coefficient to obtain the target welding parameter includes: and taking the product of the reference value of the welding parameter and the target adjusting coefficient as a target welding parameter.

It is to be understood that in the present embodiment, the target welding parameter includes at least one of a target arc initiation current parameter, a target arc initiation current duration, a target arc initiation voltage parameter, and a target arc initiation voltage duration.

For example, the target welding parameter may be obtained by the following formula:

target arc striking current parameter is equal to arc striking current parameter reference value Ka

Target arc striking voltage parameter (arc striking voltage parameter reference value) Ka

Target arc-striking current duration (arc-striking current duration reference value) Kt

Target arc striking voltage duration (arc striking voltage duration reference value) Kt

In this embodiment, a target adjustment coefficient is determined by the following method to adjust the reference value of the welding parameter: determining an initial adjustment coefficient of welding parameters according to the welding wire temperature characterization quantity and the adjustment weight; and determining a target adjustment coefficient according to the relationship among the initial adjustment coefficient, the maximum adjustment coefficient and the minimum adjustment coefficient. The target adjustment coefficient is obtained by comparing the initial adjustment coefficient with the minimum and maximum adjustment coefficients, so that the target adjustment coefficient is a reasonable value, and the problem that the adjusted target welding parameter is too large and the equipment cannot provide too large energy due to too large or too small target adjustment coefficient caused by errors, or the set welding effect cannot be achieved due to insufficient energy provided by the equipment due to too small adjusted target welding parameter is solved.
