Based on the hardware structure, the embodiment of the corrugated web welding method is provided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the corrugated web welding method of the present invention, and the first embodiment of the corrugated web welding method of the present invention is provided.
In this embodiment, the corrugated web welding method includes the steps of:
step S10: and acquiring the total material thickness and the profile information of the corrugated web to be welded.
It is noted that the execution body of the present embodiment may be a device including a corrugated web welding system, which may be a computing device, for example: the welding device comprises a tablet personal computer, a personal computer and the like, and can be connected with devices such as an infrared sensor, a welding camera, a welding flux box, a wire feeding wheel, a welding wire disc, a control box and the like, wherein the welding camera is used for collecting welding images and positioning welding seam positions in the welding images by combining signals collected by the infrared sensor, so that welding seam coordinates can be accurately determined. The present embodiment takes a corrugated web welding apparatus as an execution body to perform the following description of the embodiment.
It will be appreciated that the total material thickness may be the total thickness of the corrugated webs to be welded, and may be determined in accordance with the thickness and number of layers of the corrugated webs to be welded. Wherein, the time required by welding and the amount of materials required by welding can be determined through the total material thickness.
It should be understood that the contour information may refer to information generated by collecting a corrugated web image through a welding camera, and performing steel plate contour and contour size recognition on the corrugated web image. The profile information comprises information such as the length, the width, the diameter of a corrugated circular arc and the like corresponding to the corrugated web to be welded.
Step S20: and searching a corresponding target welding spot diameter in a preset welding spot diameter mapping table according to the total material thickness.
It should be noted that the preset weld spot diameter mapping table may be a preset table including a corresponding relationship between the total material thickness and the weld spot diameter. When the thicknesses of the plates are different, the corresponding welding spot diameters are determined according to the thicknesses of the plates, so that welding of plates with various thicknesses can be met, and cold welding caused by insufficient welding spot diameters is avoided.
Further, the step S20 includes: determining a target welding current range according to the total material thickness and a preset welding current mapping table; determining the minimum diameter of the nugget according to the target welding current range; and searching a corresponding target welding spot diameter in a preset welding spot diameter mapping table according to the minimum diameter of the nugget.
It should be noted that, as the welding current increases, the penetration and the weld reinforcement also increase, so that the welding current needs to be controlled, a preset welding current mapping table can be a preset corresponding relation between the thickness of the steel plate and the current required by welding, and in order to improve the welding efficiency, the current required by the current for welding is determined by matching the current of the thickness of the corrugated web to be welded through the preset welding current mapping table, so that effective welding is ensured.
It can be understood that the heat generated by the electric arcs corresponding to different currents is also different, and because the nugget diameter is related to the plate thickness, in order to ensure that the later-stage weld spot diameter meets the process standard and avoid the generation of pores or cracks caused by rough weld, the minimum nugget diameter needs to be determined according to the welding current, so that the corresponding target weld spot diameter is searched in the preset weld spot diameter mapping table according to the minimum nugget diameter.
It should be understood that the preset weld spot diameter mapping table is a preset table including correspondence among nugget diameters, currents, and weld spot diameters, where the weld spot diameters include a nugget area and a thermal coverage area corresponding to current heat, and the thermal coverage area refers to an area where heat generated by the currents may affect the steel plate, and therefore, the target weld spot diameter is determined according to the minimum nugget diameter and the thermal coverage diameter corresponding to the current heat, and the welding quality can be ensured.
Step S30: and acquiring the type of the welding joint.
It should be noted that, because different welding joints are required for welding different shapes of plates and different thicknesses of plates, different welding methods are selected for different materials of steel plates, wherein the welding joint types can be determined according to different welding modes, including fusion welding, pressure welding, and brazing, the welding joint types can be divided into a fusion welding joint, a pressure welding joint, and a brazing joint, the fusion welding joint includes but is not limited to a butt joint, a fillet joint, and a terminal joint, and the pressure welding joint can be an overlap joint or a butt joint.
Step S40: determining a weld angle based on a corrugated web welding algorithm and the weld joint type, the target weld spot diameter, and the profile information.
It should be noted that the corrugated web welding algorithm may be a preset algorithm for determining a welding angle corresponding to a welding gun, and the algorithm may be constructed by a form recognition algorithm and a deep learning algorithm, where the algorithm includes a CNN image recognition algorithm and a binarization form recognition algorithm.
Step S50: and adjusting the position of the welding gun according to the welding angle and then welding the corrugated web plate to be welded.
It should be noted that, the position of the welding gun is adjusted by the welding angle, so that the problem of the welding angle that the welding seam does not reach the standard can be effectively avoided.
The method comprises the steps of obtaining the total material thickness and the profile information of the corrugated web to be welded; searching a corresponding target welding spot diameter in a preset welding spot diameter mapping table according to the total material thickness; acquiring the type of a welding joint; determining a welding angle based on a corrugated web welding algorithm and the type of the welding joint, the target welding spot diameter and the profile information; according to welding angle adjustment welder's position back is right wait to weld corrugated web and weld, this embodiment compare among the prior art the manual welding corrugated web degree of difficulty greatly lead to intensity of labour big, influence production efficiency, and this embodiment has realized automatic welding and has promoted welding quality simultaneously to promote production efficiency, shorten production cycle.
Referring to fig. 3, fig. 3 is a schematic flow chart of a second embodiment of the corrugated web welding method of the present invention, which is based on the first embodiment shown in fig. 2.
In this embodiment, the step S40 includes:
step S401: and determining welding groove information and welding seam information according to the type of the welding joint and the outline information.
The welding groove refers to a pre-processing form of a joint part or an end face of the corrugated web to be welded, wherein the welding groove information comprises a groove shape and a groove size, and the groove is divided into various groove forms such as an I-shaped groove (without a groove), a V-shaped groove, a Y-shaped groove, a double Y-shaped groove, a U-shaped groove and a double U-shaped groove according to the shape of the groove. The weld information includes information such as weld length, width, residual height, and weld angle.
Understandably, in order to ensure the welding effect, the shape and size of the welding groove and the information such as the length, width, extra height and angle of the welding seam need to be determined according to the type of the welding joint and the profile information of the steel plate to be welded, so that the welding effect is ensured.
Step S402: and predicting the position of the welding spot based on the corrugated web welding algorithm, the welding groove information and the welding spot information to obtain the predicted welding spot position.
It should be noted that, before welding the corrugated web, the weld point position needs to be predicted, so the weld point position needs to be predicted through the corrugated web welding algorithm, the welding groove information, and the weld information.
Step S403: and determining a welding angle according to the welding seam information, the predicted welding spot position and the target welding spot diameter.
It should be noted that the welding angle determines the final effect of the welding seam, and in order to avoid rework in the later period, the welding angle needs to be determined according to the welding seam information, the predicted welding spot position and the target welding spot diameter.
Further, the step S403 further includes: determining a welding wire inclination angle according to the thickness and the width of the welding seam in the welding seam information; and determining a welding angle according to the welding wire inclination angle, the predicted welding spot position and the target welding spot diameter.
It should be noted that the inclination angle of the welding wire refers to an angle between the filler and the object to be welded during welding, wherein the inclination angle of the welding wire is divided into two directions of forward inclination and backward inclination of the welding wire, and the specific angle can be adjusted according to actual conditions. The direction and the size of the inclination angle are different, and the force and the heat action of the electric arc on the molten pool are also different, so that the welding seam forming is influenced.
It will be appreciated that the welding angle determines the angle of the welding gun, and that different welding seams require different angles of the welding gun, for example: and (3) welding a flat weld, wherein the angle of a welding wire needs to be finely adjusted according to the angle of a plate, the angle of a welding gun needs to be determined according to the angle of the weld, and when the weld is the flat weld, the angle of the welding gun needs to be perpendicular to 90 degrees.
In this embodiment, the step S50 includes: acquiring weld penetration information in real time; adjusting the dip angle of the welding wire according to the welding seam penetration information, the welding seam thickness and the welding seam width; and adjusting the position of a welding gun according to the adjusted welding wire inclination angle, the predicted welding point position and the target welding point diameter, and then welding the corrugated web plate to be welded.
It should be noted that the weld penetration information refers to the distance from the surface of the weldment to the deepest portion of the molten zone in the butt weld. Because the thickness of the welding seam, the width of the welding seam and the surplus height of the welding seam can be influenced by welding current, in order to avoid unsmooth welding seam caused by excessive melting of the welding wire due to the influence of the current, the inclination angle of the welding wire needs to be adjusted according to the welding seam penetration information, the thickness of the welding seam and the width of the welding seam.
In specific implementation, the corrugated web to be welded is welded after the position of a welding gun is adjusted according to the adjusted welding wire inclination angle, the predicted welding point position and the target welding point diameter.
The method comprises the steps of obtaining the total material thickness and the profile information of the corrugated web to be welded; searching a corresponding target welding spot diameter in a preset welding spot diameter mapping table according to the total material thickness; acquiring the type of a welding joint; determining welding groove information and welding seam information according to the type of the welding joint and the outline information; predicting the position of a welding spot based on a corrugated web welding algorithm, the welding groove information and the welding information to obtain a predicted welding spot position; determining a welding angle according to the welding seam information, the predicted welding spot position and the target welding spot diameter; according to welding angle adjustment welder's position back is right wait to weld corrugated web and weld, this embodiment compare among the prior art the manual welding corrugated web degree of difficulty greatly lead to intensity of labour big, influence production efficiency, and this embodiment has realized automatic welding and has promoted welding quality simultaneously to promote production efficiency, shorten production cycle.

In this embodiment, after the step S50, the method further includes:
step S60: and acquiring an image of the welded corrugated web.
It should be noted that, the image of the welded corrugated web is collected by the camera, and the image can be used to judge whether the weld seam meets the preset index.
Step S70: and carrying out weld joint identification on the corrugated web image based on a deep learning algorithm to obtain weld joint parameter information.
It should be noted that the weld parameter information refers to information under parameters corresponding to a weld generated after welding, and the parameter information includes information such as a length, a width, and an angle of the weld. The method comprises the steps of carrying out weld joint identification on a corrugated web image based on a deep learning algorithm, denoising the corrugated web image, removing interference factors, extracting and retaining information useful for later image processing, and denoising the image through algorithms such as image graying, binaryzation, filtering and the like. The filtering algorithm comprises algorithms such as mean filtering, median filtering and the like. In practical application, firstly, the pixel gray value of an image is classified, a background and an object are separated through a global threshold value method, after a separated result is obtained, a weld object is extracted from the separated image through a background difference method, contour information of the object is extracted based on edge detection, weld parameter information is determined according to the contour information, the extracted image is segmented, interference of other welding residues is reduced, and weld characteristics are extracted to the maximum extent.
Step S80: and judging whether the weld defects exist according to the weld parameter information and preset weld indexes.
It should be noted that, whether the weld defect exists or not is comprehensively judged by comparing the weld angle, the weld length and the weld width in the weld parameter information with the preset weld index, so as to facilitate the timely repair in the later period.
The method can be understood that the preset welding seam indexes are preset and used for judging whether the welded welding seam reaches the standard or not, the indexes comprise welding seam parameter indexes, and the welding seam parameter indexes comprise welding sizes, welding leg heights and welding seam straightness parameters corresponding to the welding seam.
Further, the step S80 includes: determining external forming quality according to the welding size, the height of a welding leg and the straightness of the welding line in the welding line parameter information; determining the internal welding quality according to the cracks and the air holes in the welding seam parameter information; and judging whether welding defects exist or not according to the external forming quality, the internal welding quality and preset welding seam indexes.
It should be noted that, in order to determine whether the weld has a defect, the defect type is determined, that is, the defect source is determined by determining the defect type, so as to determine whether the defect can be remedied.
Step S90: and when the welding seam defect exists, repairing the welding seam until the preset welding seam index is met.
Further, the step S90 further includes: determining a weld defect processing strategy according to the defect type corresponding to the weld defect; carrying out coping or repair welding on the welding seam according to the welding seam defect processing strategy; acquiring a target weld image in a preset processing area in real time; and adjusting welding seam maintenance parameters according to the target welding seam image until the welding seam in the obtained target welding seam image meets the preset welding seam index.
