Problems solved by technology

[0013] However, since the anti-stick treatment has an impact on the cycle time, it is better to have a short processing time
However, if the time required for the anti-adhesion treatment is forcibly shortened, problems such as contact tip or base metal deposition may occur, or the welding wire protruding from the contact tip may become an inappropriate length, causing trouble in the next welding process. The time required for arc processing becomes longer, and the cycle time becomes longer due to failure of arc start
In addition, when the time required for anti-adhesive treatment is forcibly shortened, it may adversely affect weldability

Embodiment approach 1

[0075] figure 1 It is a schematic diagram showing the arc welding system according to Embodiment 1. The arc welding system according to this embodiment is a consumable electrode type gas shielded arc welding machine, and includes a welding robot 1 , a welding power source 2 , a control device 3 , an imaging device 4 , and an arc crater adjustment device 5 . The arc crater adjustment device 5 is provided on the control device 3 . In addition, for the convenience of drawing and description, it is described that the components of the arc crater adjustment device 5 are included in the control device 3, but the control device 3 and the arc crater adjustment device 5 can also be a seamless structure, and it can also be seen that they are controlled by the control device. The hardware and software of the device 3 realize the function of the arc crater adjustment device 5 . In addition, the arc crater adjustment device 5 may be provided in the welding power source 2, or may be provi...

Embodiment approach 2

[0133] The arc crater adjustment device 205, the welding system, the arc crater adjustment method, and the computer program 50d according to the second embodiment are different from those of the first embodiment in that the process adjustment unit 55 and the shortest process storage unit 57 of the first embodiment are composed of a deep neural network. Therefore, the above-mentioned differences will be mainly explained below. Since other structures and effects are the same as those in the embodiment, corresponding parts are assigned the same reference numerals and detailed descriptions are omitted.

[0134] Figure 6 It is a functional block diagram showing the arc crater adjustment device 205 according to the second embodiment. The arc crater adjustment device 205 according to Embodiment 2 is the same as Embodiment 1, and includes a welding monitoring data acquisition unit 51a, an image data acquisition unit 51b, a first good / failure judging unit 52a, a second good / failure jud...

Embodiment approach 3

[0164] Figure 8It is a functional block diagram showing the arc crater adjustment device 305 according to the third embodiment. The arc crater adjustment device 305 , the welding system, the arc crater adjustment method, and the computer program 50d according to the third embodiment are different from those of the second embodiment in terms of data input to the process adjustment unit 355 , so the differences will be mainly described below. Since other structures and effects are the same as those in the embodiment, corresponding parts are assigned the same reference numerals and detailed descriptions are omitted.

[0165] The arc crater adjustment device 305 according to Embodiment 3 further includes a welding condition data acquisition unit 51c. The welding condition data acquisition part 51c acquires welding condition data. The welding condition data includes, for example, information such as the material of the base material A, the groove shape, the welding current setti...

Abstract

The arc crater adjustment device (5) adjusts the arc crater process in repeated welding processes, and includes: an acquisition unit that acquires welding data indicating a welding state involved in the next welding process; and a process adjustment unit based on the The welding data obtained by the acquisition unit is used to adjust the arc crater process, so that the cycle time of the welding process is shortened.

Description

technical field [0001] The present invention relates to an arc end adjustment device, a welding system, an arc end adjustment method and a computer program for adjusting an arc end process in a welding process. Background technique [0002] As one of the welding methods, there is a consumable electrode type gas shielded arc welding method. The gas shielded arc welding method is a technique in which an arc is generated between the welding wire fed to the welded part of the base material and the base material, and the base material is welded with the heat of the arc. Welding is performed by spraying shielding gas to the periphery of the welded part. [0003] In continuous production, in the case of arc welding using a welding robot, after the welding torch is moved to the welding start position, the welding wire is decelerated, and the arc start process of supplying the welding current at the timing when the welding wire contacts the base metal is used. Arcing occurs. In ad...
