[0068] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0069] Figure 1 A flow chart of a layer plate wrapping annealing weld control method of the present invention is shown.

[0070] like Figure 1 As shown, the present invention discloses a layer plate wrapping annealing weld control method, comprising:

[0071] S101, obtaining layer welding information;

[0072] S102, obtaining the characteristics of the layer plate welding and the corresponding characteristic values ​​according to the layer plate welding information;

[0073] S103, determining the parameters of the corresponding annealing weld according to the characteristics of the layer welding and the corresponding characteristic values;

[0074] S104, controlling the annealing weld based on the parameters.

[0075] According to an embodiment of the present invention, the features in the layer plate welding information include layer plate features and weld seam features, for example, the layer plate features include the thickness of the layer plate, and the weld seam features include the temperature value of the weld seam and the width of the weld seam, etc.; the parameters of the annealing weld include the position, implementation time, length and width of the annealing weld seam, etc. The annealing weld seam is precisely controlled by the parameters, thereby improving the toughness of the weld seam.

[0076] According to an embodiment of the present invention, the step of obtaining the characteristics of the layer plate welding and the corresponding characteristic values ​​includes:

[0077] Extract thickness features and corresponding thickness values ​​from the layer welding information;

[0078] Determine whether the thickness value is greater than a preset thickness threshold, if so, the corresponding layer plate welding is a multi-layer welding method; if not, the corresponding layer plate welding is a thick plate welding method;

[0079] Based on the welding method, query in the preset annealing weld bead position table to obtain the position of the annealing weld bead corresponding to the welding method;

[0080] The welding method includes a multi-layer welding method and a thick plate welding method.

[0081] It should be noted that the thickness feature in the layer plate welding information is the layer plate thickness, and the preset annealing weld bead position table stores various welding methods and the positions of the annealing weld bead corresponding to the welding methods. For example, the position of the annealing weld bead corresponding to multi-layer welding is the surface of the weld, and the position of the annealing weld bead corresponding to thick plate welding is the root of the weld, etc.

[0082] According to an embodiment of the present invention, the step of obtaining the characteristics of the layer plate welding and the corresponding characteristic values ​​further includes:

[0083] Extract the temperature characteristics and corresponding temperature values ​​in the layer welding information;

[0084] Based on the time sensor, the time node is obtained, and the temperature value is marked according to the time node to obtain the temperature value of different time nodes;

[0085] Sort the temperature values ​​at different time nodes in chronological order and construct a time-temperature curve;

[0086] Based on the time-temperature curve, predict the theoretical time node where the preset first temperature threshold is located;

[0087] The theoretical time node is set as the implementation time of the corresponding annealing weld and sent to a preset management terminal for prompting.

[0088] According to an embodiment of the present invention, the preset first temperature threshold is the temperature value at which the annealing weld is started. The preset first temperature threshold is input into the constructed time-temperature curve to obtain a time node, and the time node is set to the theoretical time node where the preset first temperature threshold is located.

[0089] According to an embodiment of the present invention, the step of extracting temperature characteristics and corresponding temperature values ​​in the layer plate welding information further includes:

[0090] Based on the preset temperature sensor, obtain the temperature detection value;

[0091] Extract any two values ​​from the temperature detection values ​​and perform difference calculation to obtain the temperature detection difference;

[0092] If the temperature detection difference is greater than a preset temperature detection difference threshold, extracting the farthest point where the large value of the temperature detection value corresponding to the temperature detection difference is located;

[0093] Taking the farthest point where the maximum value of the temperature detection value corresponding to the temperature detection difference is located as the reference, the welding seam is cooled down;

[0094] If the temperature detection difference is less than or equal to a preset temperature detection difference threshold and the smaller value among the temperature detection values ​​corresponding to the temperature detection difference is less than or equal to a preset second temperature threshold, extracting the minimum value among the temperature detection values;

[0095] The minimum value among the temperature detection values ​​is set as the temperature value in the layer plate welding information.

[0096] It should be noted that the cooling treatment includes at least one of air cooling, solidification cooling, etc. When air cooling is used, the direction of air movement in the air cooling is from the farthest point where the large value of the temperature detection value corresponding to the temperature detection difference is located to the other end of the weld.

[0097] According to an embodiment of the present invention, it also includes:

[0098] Extract weld positions from plate welding information;

[0099] According to the weld position in the layer plate welding information, the shape of the weld is obtained;

[0100] Based on the shape of the weld, determine the center position corresponding to the weld position;

[0101] If the center position of the weld position is within the shape of the corresponding weld, then the center position is used as the reference point, and at least one temperature sensor is set at the farthest points on both sides of the weld, and at least one temperature sensor is set at the reference point;

[0102] If the center position of the weld is not within the corresponding weld shape, find the point closest to the outer edge of the weld shape as the reference point, set at least one temperature sensor at the farthest points on both sides of the weld, and set at least one temperature sensor at the reference point.

[0103] It should be noted that temperature sensors are respectively arranged at both ends and in the middle of the weld, with at least one being arranged at each position to reduce detection errors.

[0104] According to an embodiment of the present invention, it also includes:

[0105] Obtain the historical theoretical time node and the historical actual time node where the preset first temperature threshold is located;

[0106] Subtract the historical theoretical practice node from the historical actual time node to obtain the first time difference;

[0107] If the absolute value of the first time difference is less than or equal to the preset first time difference threshold, the corresponding first time difference is retained;

[0108] Calculate the average value of the retained first time difference to obtain a time revision value;

[0109] The time revision value is added to the theoretical time node where the preset first temperature threshold is located to obtain the revised theoretical time node.

[0110] It should be noted that the theoretical time node where the preset first temperature threshold is located is revised through historical data to improve the accuracy of the implementation time of the annealing weld.

[0111] According to an embodiment of the present invention, the step of obtaining the characteristics of the layer plate welding and the corresponding characteristic values ​​further includes:

[0112] Extract the weld width and weld length when welding the layer plates;

[0113] According to the preset weld width range and the preset weld length range of the weld width during the layer plate welding, the preset annealing weld bead width and length list is searched to obtain the width and length of the corresponding annealing weld bead;

[0114] Obtain image information after the layer welding is completed;

[0115] Extract the features and corresponding feature values ​​in the image after the layer welding is completed;

[0116] When the feature value in the image after the layer plate welding is completed is greater than or equal to the corresponding preset feature value, the ratio of the corresponding feature in the image after the layer plate welding is completed is set to 1;

[0117] When the characteristic value in the image after the layer plate welding is completed is less than the corresponding preset characteristic value, the characteristic value in the image after the layer plate welding is completed is divided by the corresponding preset characteristic value to obtain a ratio of the corresponding characteristic;

[0118] Multiply the feature ratio by the preset influence weight coefficient of the corresponding feature, and then add them up to obtain a first revision coefficient;

[0119] The width and length of the annealing weld bead are divided by the first revision coefficient respectively to obtain the revised width and length of the annealing weld bead.

[0120] It should be noted that the width and length of the annealing weld are determined by the width and length of the weld of the layer plate welding and the effect of the welding completion. The better the welding completion effect, the greater the ratio of the features in the image after the layer plate welding is completed, and the greater the corresponding first revision coefficient. The width and length of the annealing weld are directly proportional to the width and length of the weld, and inversely proportional to the effect of the welding completion. The preset annealing weld width and length list is divided into an annealing weld width subtable and an annealing weld length subtable. The annealing weld width subtable stores Weld widths of various width ranges and multiple annealing bead widths, and each weld width range corresponds to an annealing bead width. For example, if the weld width during layer welding falls into weld width range a, then the corresponding annealing bead width is found according to weld width range a; the annealing bead length subtable stores weld lengths of various length ranges and multiple annealing bead lengths, and each weld length range corresponds to an annealing bead length. For example, if the weld length during layer welding falls into weld length range b, then the corresponding annealing bead length is found according to weld length range b.

[0121] According to an embodiment of the present invention, the step of constructing a time-temperature curve specifically includes:

[0122] With the time node as the horizontal coordinate and the temperature value as the vertical coordinate, a two-dimensional coordinate of time-temperature is constructed;

[0123] Based on a preset first time range, different time nodes and corresponding temperature values ​​are divided into multiple intervals;

[0124] Use the preset algorithm to construct a linear equation using the coordinates in the same interval;

[0125] Extract the distance from the coordinates in the same interval to the linear equation of the corresponding interval, and calculate the mean to obtain the average distance value;

[0126] If the average distance value is greater than a preset first average distance threshold, the corresponding interval is evenly divided into two sub-intervals with the same number of coordinates, and the linear equation is reconstructed using the coordinates in the sub-intervals.

[0127] It should be noted that, for example, if the preset algorithm is the least squares method, when the average distance value is greater than the preset first average distance threshold, it means that the error of the current time-temperature curve is relatively large. Therefore, the linear equation is divided into two linear equations to improve the accuracy of predicting the theoretical time node where the preset first temperature threshold is located. If the average distance value from the coordinates in the sub-interval to the corresponding linear equation is greater than the preset first average distance threshold, the corresponding sub-interval will continue to be divided until the average distance value from the coordinates in the corresponding sub-interval to the corresponding linear equation is less than or equal to the preset first average distance value or there are only two coordinates in the corresponding sub-interval; when the coordinates in the interval or sub-interval are even numbers, the corresponding interval or sub-interval is evenly divided from the middle; if the interval or sub-interval When the coordinate in the interval is odd, the interval or sub-interval is divided based on the middle coordinate in the interval or sub-interval, and the middle coordinate is placed in the corresponding two sub-intervals to construct the linear equation. The middle coordinate in the linear equation with the larger average distance value corresponding to the coordinate in the corresponding sub-interval is deleted, and the linear equation is reconstructed. For example, both sub-intervals a and b contain corresponding middle coordinates. The linear equation of sub-interval a containing the middle coordinate and the linear equation of sub-interval b containing the middle coordinate are constructed respectively, where the average distance value from the coordinate in sub-interval a to the linear equation is A, and the average distance value from the coordinate in sub-interval b to the linear equation is B. If A is greater than or equal to B, the middle coordinate in sub-interval b is deleted, and the linear equation of sub-interval b is reconstructed.
