Description

Technical Field

[0001] This invention relates to the field of dual-wire gas metal arc welding technology, and in particular to a method, actuator, terminal and medium for controlling dual-wire welding in phase. Background Technology

[0002] Twin-wire welding in gas metal arc welding (GMAW) consists of two MIG / MAG welding power sources, one for the front wire and one for the rear wire, two wire feeders, and one welding torch. The two power sources communicate and coordinate with each other. Twin-wire welding is increasingly widely used due to its higher deposition efficiency, higher welding speed, stable welding process, and good welding performance, especially in welding long straight seams on medium-thick plates. Using twin-wire welding can increase efficiency by more than twice compared to ordinary single-wire welding. In twin-wire welding control modes, based on the phase matching relationship between current and voltage, there are in-phase mode, out-of-phase mode, and random mode. In-phase mode, because the front and rear wires simultaneously output peak current, the heat input is increased by superposition, effectively achieving a deeper penetration depth. It is widely used in welding scenarios involving medium-thick plates where a large penetration depth is required but the cut is small. However, when using the same-phase mode welding, the interference between the two arcs is very strong because the front and rear wire arcs output peak currents at the same time. In order to reduce the interference between the arcs, a dual-wire welding gun with a larger contact tip spacing is usually used. To ensure a faster welding speed for dual-wire welding, the distance between the two contact tips should not exceed 20mm.

[0003] Dual-wire welding torches are only available in two fixed-pitch specifications: 10mm and 15mm. This often fails to achieve optimal results for different welding needs. Increasing the contact tip pitch to 12mm or 14mm results in a large number of torch models, making selection, use, and maintenance very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method, execution device, terminal and medium for controlling in-phase twin-wire welding, which calculates and adjusts the distance between the conductive nozzles in real time, solves the welding quality problem caused by improper twin-wire distance, and improves the adaptability of twin-wire welding process and the consistency of welding quality.

[0010] Combining the first adjustment amount and the second adjustment amount, the final adjustment amount of the conductive nozzle spacing is calculated and transmitted to the actuator for adjusting the conductive nozzle spacing.

[0011] Furthermore, after entering the main welding stage, within the first 500ms, the standard values ​​of the peak voltage and the base voltage are calculated based on the current change data. Specifically, the following methods are used:

[0023] Where: TrchDis Adj Indicates the final adjustment amount for the contact tip spacing; TrchDis std Indicates the initial spacing between the contact tips; KP Adj This represents the adjustment factor used when calculating the final spacing.

[0024] Secondly, the present invention provides an execution device for a co-phase dual-wire welding control method, comprising a welding power source, at least two servo motors, at least two welding torch tubes, a welding torch sliding support, a rotating locking block, a locking sleeve, and a conductive nozzle; the welding torch sliding support has a sliding groove, the servo motors are fixedly connected to the welding torch tubes, and the angle between the welding torch tubes changes in real time according to the movement of the servo motors; the other side of the welding torch tube is connected by a rotating locking block, the axial position of the welding torch tube is locked by a locking sleeve, and the conductive nozzle is connected to the welding torch tube; the welding power source is electrically connected to the servo motors, and the welding power source includes a processor for implementing the method described in any one of the first aspects.

[0028] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0029] (1) In view of the problem of arc interference in the dual-wire in-phase welding mode, this invention proposes a control method that calculates and automatically adjusts the distance between the conductive nozzles by software control algorithm. It can dynamically adjust the distance between the conductive nozzles in the welding torch structure in real time according to the changes in current and voltage during the welding process. By accurately calculating the standard values ​​of peak voltage and base voltage, and combining the deviation between the actual feedback value and the standard value, the adjustment amount of the conductive nozzle distance is determined, thereby realizing the fine control of the dual-wire welding process parameters, thus effectively reducing the mutual influence between the front and rear wire arcs, and overcoming the problem that traditional fixed-gap welding torches are difficult to adapt to different welding conditions.

[0030] (2) This invention reduces the need for multiple models of twin-wire welding guns due to different welding requirements. Users only need to use one twin-wire welding gun with automatic spacing adjustment function to cope with welding operations under various working conditions, which reduces the equipment purchase cost of enterprises, simplifies the selection difficulty of on-site operators and the subsequent maintenance work, and improves the versatility and flexibility of welding equipment.

[0038] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical solution of the present invention, rather than limitations thereof. In the absence of conflict, the embodiments of the present invention and the technical features in the embodiments can be combined with each other.

For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0040] Example 1

[0041] Figure 1 This is a flowchart of a method for controlling in-phase twin-wire welding according to Embodiment 1 of the present invention. This flowchart only illustrates the logical sequence of the method described in this embodiment. Provided there are no conflicts, different methods may be used in other possible embodiments of the present invention. Figure 1 Complete the steps shown or described in the order indicated.

[0042] This embodiment is a typical implementation of the present invention, providing a method for controlling in-phase twin-wire welding. This method can be applied to a terminal and executed by an electronic terminal. The electronic terminal can be implemented in software and / or hardware and can be integrated into a terminal, such as any smartphone, tablet, or computer device with communication capabilities. Figure 1 As shown, the method in this embodiment specifically includes the following steps:

[0043] Acquire current change data within a preset time period after the in-phase twin-wire welding enters the main welding stage, and calculate the standard value of peak voltage and the standard value of base voltage based on the current change data.

[0044] The peak voltage change is calculated based on the actual feedback values ​​of the peak voltages of the front and rear wires monitored in real time and the standard value of the peak voltage, and the first adjustment amount of the contact tip spacing caused by the peak voltage change is calculated.

[0045] The base voltage change is calculated based on the actual feedback values ​​of the base voltage of the front and rear wires monitored in real time and the standard value of the base voltage, and the second adjustment amount of the contact tip spacing caused by the base voltage change is also calculated.

[0046] By combining the first adjustment amount and the second adjustment amount, the final adjustment amount of the conductive nozzle spacing is calculated and transmitted to the actuator for adjusting the conductive nozzle spacing.

[0047] Specifically, such as Figure 3As shown, the pulse waveform consists of a rising phase, a peak phase, a falling phase, and a base phase. Different parameters correspond to different phases, such as peak voltage and peak current in the peak phase, and base voltage and base current in the base phase.

[0048] Relevant expert data, such as peak voltage IPV, is stored in the welding power source as initial values. ini Base voltage IBV ini Peak current IPA ini Base current IBA ini wait.

[0049] Furthermore, calculate the standard values ​​of the peak-base voltages of the front and rear wires:

[0050] like Figure 4 As shown, since dual-wire pulse welding is current-controlled, the feedback voltage changes with the current. Therefore, the standard values ​​of the peak voltage and the base voltage are calculated based on the change of current. This calculation process uses the time within 500ms of entering the main welding stage.

[0051] Welding is divided into three stages: arc initiation, main welding, and arc termination. The parameters during the arc initiation stage are constantly updated as the wire feed speed changes. Once the main welding stage is reached, the wire feed speed reaches the set value, and the corresponding welding parameters no longer change. After entering the arc termination stage, the wire feed speed continuously decreases until it reaches zero, and the welding parameters also change during this stage.

[0052] Specifically, after entering the main welding phase, within the first 500ms, the standard values ​​of the peak voltage and base voltage are calculated:

[0053]

[0054]

[0056] Further, calculate the adjustment amount for the contact tip spacing:

[0057] During the welding process, the feedback values ​​of peak voltage and base voltage are detected in real time, and the adjustment amount of the contact tip spacing is calculated based on the changes in the peak voltage of the front wire and the back wire and the changes in the base voltage.

[0058] Based on the deviation between the actual feedback values ​​of the peak voltages of the front and rear wires and the standard values, calculate the first adjustment amount for the contact tip spacing:

[0059]

[0060] In the formula, TrchDis IPV This indicates the first adjustment amount of the contact tip spacing due to changes in peak voltage; KP IPV This represents the contact tip adjustment spacing coefficient caused by changes in peak voltage; IPV Lfed Indicates the actual feedback value of the peak voltage of the front wire; IPV Lstd Indicates the standard value of the peak voltage of the front wire; IPV Tfed Indicates the actual feedback value of the peak voltage at the back wire; IPV Tstd This indicates the standard value of the peak voltage of the back wire.

[0061] Based on the deviation between the actual feedback values ​​of the base voltage of the front and rear wires and the standard values, calculate the second adjustment amount of the contact tip spacing:

[0062]

[0063] In the formula, TrchDis IBV This indicates the second adjustment amount of the contact tip spacing due to changes in the base voltage; KP IBV This represents the contact tip adjustment spacing coefficient caused by changes in the base voltage; IBV Lfed Indicates the actual feedback value of the base voltage of the front wire; IBV Lstd Indicates the standard value of the base voltage of the front wire; IBV Tfed Indicates the actual feedback value of the back wire base voltage; IBV Tstd This indicates the standard value of the back wire base voltage.

[0064] Finally, the final adjustment amount of the contact tip spacing is calculated and sent to the actuator:

[0065]

[0066] Where: TrchDis Adj Indicates the final adjustment amount for the contact tip spacing; TrchDis std Indicates the initial spacing between the conductive tips; KP Adj This represents the adjustment factor used when calculating the final spacing.
