The invention relates to the technical field of welding, in particular to a welding arc striking energy control method and device.
Background
For gas metal arc welding, the whole welding process can be roughly divided into three processes, namely an arc striking process, a main welding process and a back firing process. The energy of the arc striking process is generally given in the welding machine, the arc striking energy is fixed, and the welding power supply controls the welding arc striking according to the arc striking energy given in the welding machine.
However, this approach may result in poor uniformity of the striking performance in the striking stage, for example, the striking performance of the cold striking (the temperature of the wire tip is room temperature) and the striking performance of the hot striking (the temperature of the wire tip is high and the wire tip is red and hot) are different at the same striking energy, and if the striking state of the cold striking is normal, the hot striking is easy to cause the phenomenon of burning on the striking arc at this time, i.e. the striking energy is too large. Obviously, the arc striking energy required by the cold arc striking process is higher, and the arc striking energy required by the hot arc striking process is relatively lower, so that the arc striking process obviously causes inconsistent arc striking performance of the arc striking process according to fixed energy output, thereby causing welding defects such as unstable welding or concentrated welding seam stress.

Detailed Description
The application is further described in detail below by means of the figures and examples. The features and advantages of the present application will become more apparent from the description.
The word "exemplary" is used herein to mean "serving as an example, embodiment, or illustration. Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are illustrated in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
In addition, the technical features described below in the different embodiments of the present application may be combined with each other as long as they do not collide with each other.
The higher the striking energy required by the cold striking process, and the lower the striking energy required by the hot striking process, the lower the striking energy required by the higher the welding wire surface temperature, which is in a certain relation with the welding wire surface temperature; the lower the wire surface temperature, the higher the required arc striking energy.
The inventors further found that the surface temperature of the welding wire at the current arc striking time is related to the time interval between the last welding end time and the current arc striking time: the longer the time interval is, the longer the welding wire cooling time is, and the lower the surface temperature of the welding wire at the moment of the current arc striking is; the shorter the time interval, the shorter the welding wire cooling time, and the higher the welding wire surface temperature at the current arc striking time. Therefore, the amount of arc striking energy required for each arc strike is related to the length of time the wire is cooled.
With the above findings in mind, an embodiment of the present invention provides a welding arc striking energy control method for improving welding strength and ensuring weld flatness, where the method is shown in fig. 1, and includes:
Step 101: determining standard cold striking energy;
Step 102: determining a first time interval between each arc striking time and the last welding end time and the surface temperature of the welding wire at the last welding end time;
step 103: determining welding arc striking energy corresponding to each arc striking moment according to standard cold arc striking energy, a first time interval and the welding wire surface temperature;
Step 104: and controlling the output of the welding equipment at each arc striking moment according to the welding arc striking energy corresponding to each arc striking moment.
In a specific embodiment, the standard cold arc striking energy is the arc striking energy output after the welding equipment is started for the first time, namely the arc striking energy given in the welding equipment, and the arc striking energy is the quantity of current multiplied by voltage multiplied by time, namely the current and the voltage output in a period of time. In particular, the welding equipment is typically a standard welding power supply.
After the standard cold arc striking energy is determined, a first time interval between each arc striking time and the last welding end time and the surface temperature of the welding wire at the last welding end time are determined.
Next, determining welding arc striking energy corresponding to each arc striking moment according to the standard cold arc striking energy, the first time interval and the welding wire surface temperature, and specifically, as shown in fig. 2, the method comprises the following steps:
Step 201: determining a second time interval required for cooling the surface temperature of the welding wire to the room temperature after the last welding corresponding to each arc striking moment according to the surface temperature of the welding wire;
step 202: and determining welding arc striking energy corresponding to each arc striking moment according to the standard cold arc striking energy, the first time interval and the second time interval.
In the specific implementation of step 201, multiple welding tests can be performed, the time length required for cooling the surface temperature of different welding wires to the room temperature after each welding is finished is determined, and each time length and the corresponding temperature tracing point of the surface of the welding wire are drawn into a correlation curve or data analysis is performed by using software to determine the correlation between the time length and the corresponding temperature tracing point of the surface of the welding wire. After the association relation is determined, a corresponding second time interval can be determined according to the surface temperature of the welding wire after the last welding is finished, and if the time interval between the current arc striking time and the last welding finishing time exceeds the second time interval, the arc striking is cold; if the energy of the thermal arc is not exceeded or equal to the energy of the thermal arc, the thermal arc is started, and different arc starting energies can be determined according to the thermal arc starting energy.
Accordingly, step 202 performs the process, as shown in fig. 3, including:
Step 301: comparing the values of the first time interval and the second time interval;
step 302: if the value of the first time interval is larger than that of the second time interval, determining the standard cold arc striking energy as welding arc striking energy corresponding to the arc striking moment;
Step 303: and if the value of the first time interval is smaller than or equal to the value of the second time interval, determining welding arc striking energy corresponding to the arc striking moment according to the standard cold arc striking energy, the first time interval, the second time interval and the arc striking energy adjustment coefficient.
The welding arc striking energy corresponding to the arc striking moment is determined according to the following formula according to standard cold arc striking energy, a first time interval, a second time interval and an arc striking energy adjustment coefficient:
En＝E1+k×E1×(t1,n-t2,n)，n>1
Wherein t 1,n≤t2,n;En represents welding arc striking energy corresponding to the nth arc striking moment, and J; n represents the sequence number of the arc striking moment, the number of the arc striking times is recorded as n after starting the welding equipment; e 1 represents standard cold striking energy, J; k represents an arc striking energy adjustment coefficient and a constant term; t 1,n represents a first time interval s between the nth striking moment and the last welding end moment; t 2,n represents a second time interval s required for cooling the surface temperature of the welding wire to room temperature after the last welding corresponding to the nth arc striking time is finished.
In a specific embodiment, k is a constant term between 0 and 1, and a specific value can be obtained through multiple welding arc striking tests. Through multiple tests of the inventor, the value of t 2,n is stabilized at about 7s, in a specific embodiment, the approximate value t 2 can be taken for calculation, and the calculation is not needed to be solved according to the determined association relation, so that the calculation speed can be further increased, the calculation amount is reduced, and the influence on the accuracy of a calculation result is small. It will be appreciated by those skilled in the art that the value of t 2 is not only about 7s, but that the value of t 2 is obtained from a practical number of weld initiation tests, and is not limited thereto.
In implementation, when t 2,n is determined as a fixed approximate value t 2, as shown in fig. 4, the correlation between E n and E 1 can be seen, and when each arc is started, the arc starting energy required to be given is related to t 1,n, and in implementation, t 1,n is calculated by an internal timer of the welding device.
After the welding arc striking energy corresponding to each arc striking moment is determined, the output of the welding equipment at each arc striking moment is controlled according to the welding arc striking energy corresponding to each arc striking moment. Meanwhile, it should be noted that in order to ensure the normal operation of the welding equipment, after the welding equipment is shut down and restarted, the output arc striking energy is restored to the standard cold arc striking energy, i.e. the output of the arc striking energy of the first arc striking after the welding equipment is started does not need to be controlled.
Based on the same inventive concept, the embodiment of the invention also provides a welding arc striking energy control device, and because the principle of the problem solved by the welding arc striking energy control device is similar to that of the welding arc striking energy control method, the implementation of the welding arc striking energy control device can refer to the implementation of the welding arc striking energy control method, and the repetition is omitted, and the specific structure is shown in fig. 5:
