Description
Technical Field
The invention relates to the technical field of welding control, in particular to a welding control method, a welding control system, welding control equipment and a storage medium of a double-wire welding system.
Background
With the development of welding technology, gas metal arc welding is more and more applied to actual welding operation, and the technology is more and more mature. In recent years, the demand for high speed and high efficiency of gas metal arc welding has increased, and many high efficiency welding techniques such as high current gas metal arc welding, twin wire welding, hybrid welding, and the like have been derived. The twin-wire welding system comprises two welding power supplies and is mainly applied to high-speed and high-fusion-rate welding occasions. Because two welding power supplies are used, the front wire and the rear wire are distinguished according to the welding direction, the front wire power supply sends a phase signal, and the rear wire power supply outputs a pulse waveform after receiving the phase signal.
The twin-wire welding system uses two welding wires for welding, and a front-wire or rear-wire single-wire welding mode or a front-wire and rear-wire twin-wire welding mode may be used at the initial stage of welding. In the dual-wire welding mode, the front wire and the rear wire can be welded simultaneously or the front wire is welded before the rear wire or the front wire is welded after the rear wire. The modes can be switched mutually. In actual use, the front and rear wires have 6 welding switching modes as shown in table 1 below. At the 6-mode switching between the wire welding period and the welding process before and after the start, a welding defect due to poor welding may occur.
TABLE 1 welding switching modes
Specifically, in the welding stage, poor welding seams and unstable arcs in the early welding stage can be caused by the difference of welding timings of front and rear wires. When the mode is switched in the welding process, the quality defects of the welding seam, such as insufficient penetration, air holes and the like, can be caused due to the change of the mode.

Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.
As shown in fig. 1, an embodiment of the present invention provides a welding control method for a twin-wire welding system, including the following steps:
s100: acquiring a welding mode of the twin-wire welding system, wherein the welding mode is divided into two types: a single wire welding mode and a double wire welding mode;
s200: judging whether the welding mode is a double-wire welding mode or not;
if the welding mode is the monofilament welding mode, S300: the front wire or the rear wire adopts a variable frequency arc striking mode;
if the welding mode is a twin wire welding mode, S400: the method comprises the following steps that a front wire and a rear wire both adopt a variable frequency arc striking mode, the phase mode of the rear wire in an arc striking stage is determined according to a welding stage where the front wire is located, and the welding stage is divided into two types: an arc striking phase and a main welding phase.
In this embodiment, in step S400, determining the phase mode of the rear wire in the arc striking phase according to the welding phase in which the front wire is located includes the following steps:
judging whether the welding stage of the front wire is an arc striking stage;
if the front wire is in an arc striking stage, the rear wire and the front wire keep the same phase mode in the arc striking stage;
if the front wire is in the main welding stage, the rear wire maintains a different phase pattern than the front wire during the arc initiation stage.
The welding failure caused by mode switching in the welding process is essentially caused by arc striking or welding stopping of the welding power supply, and the problems caused by arc striking welding are consistent in source, so that the same solution can be adopted.
In this embodiment, in order to solve the technical problem in the prior art, if the welding mode is a single wire welding mode, both the front wire and the rear wire use a variable frequency arc striking mode. If the welding mode is a double-wire welding mode, the front wire uses a variable-frequency arc striking mode, and is switched into a constant-frequency welding mode after a period of time delay after entering a main welding stage. And if the welding mode is a double-wire welding mode, the rear wire and the front wire are simultaneously subjected to arc striking, the rear wire and the front wire are subjected to arc striking in the same phase, and after the rear wire enters the main welding stage, the mode is switched to a mode different from the phase of the front wire for welding. If the welding mode is the double-wire welding mode, the rear wire is later than the front wire to initiate arc, the front wire does not enter the main welding stage, the rear wire and the front wire are initiated with arc in the same phase, and after the front wire enters the main welding stage, the rear wire is switched to be welded in a mode different from the phase of the front wire. If the welding mode is a double-wire welding mode, the rear wire is later than the front wire to initiate arc, the front wire enters a main welding stage, and the rear wire is welded by using a mode different from the phase mode of the front wire until welding is finished.
In this embodiment, in the single-wire welding mode, since the arc length needs to be adjusted quickly, a variable frequency control mode is generally adopted, and in the double-wire welding mode, in order to stabilize the arc of the front wire and the rear wire, in the main welding stage, the front wire and the rear wire need to be phase-matched, a constant frequency control mode is generally adopted, and the rear wire and the front wire keep the same frequency.
The following describes an implementation of the welding control method of the twin wire welding system in an embodiment with reference to fig. 2 to 5.
In this embodiment, the step S100: obtaining a welding mode for a twin wire welding system, comprising: firstly, setting a welding mode of the twin-wire welding system, wherein the welding mode corresponds to the power supply use modes of two welding machines, and setting the use mode of a welding power supply according to use requirements before welding.
In this embodiment, if the welding mode is a monofilament welding mode, the current welding stage is determined;
if the current welding stage is an arc striking stage, the method continues to step S300: the front wire or the rear wire adopts a variable frequency arc striking mode, and the frequency change mode can be set as required;
if the current welding stage is the main welding stage, the welding mode of the arc striking stage is still kept, namely the front wire or the rear wire continues to adopt the variable frequency welding mode until the welding is finished, and the frequency change mode at the moment can be kept consistent with the arc striking stage.
In this embodiment, if the welding mode is the twin wire welding mode, the arc striking process and the welding process for the front wire include the steps of:
the front wire adopts a variable frequency arc striking mode, and the frequency change mode can be set as required;
after the front wire enters the main welding stage from the arc striking stage, delaying for a preset time, switching the front wire into a fixed-frequency welding mode, wherein the time length of the preset time can be set according to needs, and the frequency value of the fixed frequency can be set according to needs.
In this embodiment, if the welding mode is a monofilament welding mode, it is determined whether the front wire and the rear wire are simultaneously arc-striking;
if the front wire and the rear wire are simultaneously used for arc striking, the rear wire and the front wire simultaneously adopt a variable frequency arc striking mode, and the rear wire and the front wire keep the same phase mode in an arc striking stage. And delaying preset time after the rear wire and the front wire enter a main welding stage, switching the rear wire and the front wire into a constant-frequency welding mode, and keeping different phase modes of the rear wire and the front wire in the main welding stage.
And if the front wire is prior to the rear wire for arc striking, the rear wire adopts a variable frequency arc striking mode, and the phase mode of the rear wire in the arc striking stage is determined according to the welding stage of the front wire. Namely, if the front wire is in an arc striking stage, the rear wire and the front wire keep the same phase mode in the arc striking stage; if the front wire is in the main welding stage, the rear wire maintains a different phase pattern than the front wire during the arc initiation stage. And delaying the preset time after the rear wire enters the main welding stage from the arc striking stage, switching the rear wire into a constant-frequency welding mode, and keeping the rear wire and the front wire in different phase modes in the main welding stage.
In this embodiment, in the dual-wire welding mode, the front wire is ignited before or simultaneously with the rear wire, if the rear wire is ignited first, the front wire is immediately ignited to perform welding, and the front wire and the rear wire are in different phase welding modes. Therefore, if the welding mode is a twin wire welding mode, the method further comprises the following steps:
judging whether the rear wire is prior to the front wire to initiate arc;
if yes, immediately triggering a front wire to enter an arc striking stage, wherein the front wire and the rear wire both adopt a variable frequency arc striking mode, and the rear wire and the front wire keep the same phase mode during arc striking.
By adopting the welding control method of the novel double-wire welding system in the embodiment, when arc striking time of front and rear wires is different and the mode is switched in the welding process, the electric arc can be quickly adjusted, welding defects are avoided, and welding quality is improved.
As shown in fig. 6, an embodiment of the present invention further provides a welding control system of a twin-wire welding system, for implementing a welding control method of the twin-wire welding system, where the welding control system includes:
a welding mode obtaining module M100, configured to obtain a welding mode of the twin-wire welding system;
the monofilament welding control module M200 is used for enabling the front wire or the rear wire to adopt a variable-frequency arc striking mode if the welding mode is the monofilament welding mode;
and the dual-wire welding control module M300 is used for determining the phase mode of the rear wire in the arc striking stage according to the welding stage of the front wire if the welding mode is the dual-wire welding mode, wherein the front wire and the rear wire both adopt the variable-frequency arc striking mode.
In the welding control system of the twin-wire welding system according to the present invention, the functions of the modules may be implemented by using the specific implementation manner of the welding control method of the twin-wire welding system, which is not described herein again.
