Detailed Description
The present application is described in further detail below with reference to the figures and examples. The features and advantages of the present application will become more apparent from the description.
The word "exemplary" is used exclusively 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. While the various aspects of the embodiments are presented in 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 conflict with each other.
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 energy has a certain relation with the surface temperature of the welding wire, and the higher the surface temperature of the welding wire is, the lower the required arc striking energy is; the lower the wire surface temperature, the higher the arc initiation energy required.
The inventor further finds that the surface temperature of the welding wire at the arc striking time is related to the time interval between the last welding end time and the 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 arc striking moment is; the shorter the time interval, the shorter the cooling time of the welding wire, and the higher the surface temperature of the welding wire at the arc striking moment. Therefore, the amount of arc ignition energy required per arc ignition is related to the length of time the wire is cooled.
With the above findings, an embodiment of the present invention provides a welding arc initiation energy control method for improving welding strength and ensuring a flat weld, as shown in fig. 1, including:
step 101: determining standard cold arc ignition energy;
step 102: determining a first time interval between each arc striking moment and the last welding end moment and the surface temperature of the welding wire at the last welding end moment;
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 surface temperature of the welding wire;
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 initiation energy is arc initiation energy output after the welding equipment is started for the first time, namely, arc initiation energy given inside the welding equipment, and the arc initiation energy is current multiplied by voltage multiplied by time, namely, current and voltage output in a period of time. In particular implementations, the welding equipment is typically a standard welding power supply.
After the standard cold arc ignition energy is determined, a first time interval between each arc ignition 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 initiation energy corresponding to each arc initiation time according to the standard cold arc initiation energy, the first time interval and the surface temperature of the welding wire, and as shown in fig. 2, the specific process includes:
step 201: determining a second time interval which is required for cooling the surface temperature of the welding wire to the room temperature after the last welding corresponding to each arc striking time 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, a plurality of welding tests may be performed, the time required for cooling the surface temperature of different welding wires to room temperature after each welding is completed is determined, each time and the corresponding surface temperature of the welding wires are plotted to form an association relationship curve or data analysis is performed by using software, so as to determine the association relationship between the two. After the incidence 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 arc striking time and the last welding finishing time exceeds the second time interval, cold arc striking is performed; if the arc ignition energy does not exceed or equal to the preset value, the arc ignition is hot, and different arc ignition energies can be determined according to the arc ignition energy.
Accordingly, step 202, as shown in fig. 3, includes the following steps:
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 ignition energy as the welding arc ignition energy corresponding to the arc ignition 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 the welding arc initiation energy corresponding to the arc initiation moment according to the standard cold arc initiation energy, the first time interval, the second time interval and the arc initiation energy adjustment coefficient.
According to the following formula, determining welding arc initiation energy corresponding to the arc initiation time according to standard cold arc initiation energy, a first time interval, a second time interval and an arc initiation energy adjustment coefficient:
En＝E1+k×E1×(t1,n-t2,n)，n>1
wherein, t1,n≤t2,n；EnRepresenting welding arc striking energy J corresponding to the nth arc striking moment; n represents the serial number of the arc striking moment, counting is started after the welding equipment is started, and the number of striking the arc for the second time is counted as n; e1Represents the standard cold ignition energy, J; k represents an arc striking energy adjustment coefficient and a constant term; t is t1,nRepresenting a first time interval, s, between the nth arc striking moment and the last welding end moment; t is t2,nAnd a second time interval s corresponding to the nth arc striking moment and required for cooling the surface temperature of the welding wire to the room temperature after the last welding is finished is shown.
In a specific embodiment, k is a constant term between 0 and 1, and a specific value can be obtained through a plurality of welding arc starting tests. And subjected to a plurality of tests by the inventor, t2,nThe value of (A) is stabilized at about 7s, and in the specific embodiment, an approximate value t can be taken2And the calculation is carried out without solving according to the determined incidence relation, so that the calculation speed can be further accelerated, the calculation amount is reduced, and the influence on the precision of the calculation result is small. As will be understood by those skilled in the art, t is2The value of (A) may be not only 7s, t2The value of (b) is obtained according to actual multiple welding arc starting tests, and is not limited herein.
In specific implementation, t is2,nDetermined as a fixed approximation t2Then E isnAnd E1The correlation of (2) can be seen in fig. 4, which shows the arc striking energy and t required to be given each time arc striking is performed1,nIn connection with, when embodied, t1,nCalculated by a timer inside the welding equipment.
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, that is, the output of the arc striking energy of the first arc striking after the welding equipment is started does not need to be controlled.
