Embodiment 1

[0051] refer to figure 1 , in an embodiment of the present invention, the welding control method includes the following steps:

[0052] S100, obtaining parameter information of the welding groove;

[0053] S200. Invoking corresponding welding control parameters according to the parameter information;

[0054] S300. Control the welding robot to weld the welding groove according to the welding control parameters.

[0055]In step S100 of the embodiment of the present invention, the parameter information of the welding groove includes the starting position information of the welding groove, the end position information of the welding groove and the characteristic inflection point of the welding groove. In the embodiment of the present invention, the welding groove is detected by the welding groove detection module composed of the laser triangulation detection device and the detection acquisition processing module, wherein the laser triangulation detection device scans the weldin...

Embodiment 2

[0059] refer to figure 2 , a welding control method in the embodiment of the present invention, which is based on the welding control method in the first embodiment, and before welding the welding groove, the steps are added:

[0060] S210, obtaining temperature information of the welding groove;

[0061] S220. Determine whether the temperature information reaches a preset threshold;

[0062] Wherein, if the acquired temperature information does not reach the preset threshold, continue to acquire the temperature information of the welding groove until the acquired temperature information reaches the preset threshold.

[0063] If the acquired temperature information reaches the preset threshold, the welding control module controls the welding motion module and the welding module to weld the welding groove according to the welding control parameters and the welding control program.

[0064] In some embodiments, the temperature information of the welding groove is obtained by ...

Embodiment 3

[0066] refer to image 3 , a welding control method in the embodiment of the present invention, on the basis of the welding control method in the second embodiment, when welding the welding groove, the steps are added:

[0067] S400. Monitoring the distance information between the welding robot and the obstacle;

[0068] S410. Determine whether the distance information is smaller than a preset distance;

[0069] S510, if the distance information is less than the preset distance, stop the welding work;

[0070] S520. If the distance information is greater than the preset distance, continue to control the welding robot to weld the welding groove according to the welding control parameters and the welding control program.

[0071] In some embodiments, the distance information between the welding robot and the obstacle is acquired by being provided with an anti-collision sensor. Specifically, the anti-collision sensor is arranged in the above-mentioned welding robot body, and al...
