Embodiment Construction

[0035] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0036]

[0037] First, the welding robot system 1 according to the present embodiment will be described. figure 1 It is a figure which shows an example of the schematic structure of the welding robot system 1 which concerns on this embodiment.

[0038] like figure 1 As shown, the welding robot system 1 includes: a welding robot (manipulator) 10 for welding parts (workpieces) to be welded through electrodes; a control device (controller) 20 for controlling the welding robot 10; and a database selection device 30, Makes the selection of the database file used in the welding job.

[0039] Here, the database file refers to a table in which various work conditions related to welding (parameters related to welding work) are registered. In the present embodiment, the database file specifies welding conditions such as welding current and arc voltage ...

Abstract

The invention provides a welding system and a welding method. In a welding robot system (1), a welding robot (10) senses work-pieces before welding, and a database selection device (30) selects database files specifying the welding condition on the basis of the sensing result; a control device (20) controls the welding robot (10) for welding on the basis of the selected database files; in the process of selecting the database files, the database selection device (30) obtains the sizes, measured by sensing points, of root gaps along a welding line of the work-pieces and selects the database files on the basis of the sizes of the root gaps of the two ends of each sensing section. Thus, the welding condition guaranteeing appropriate depth of fusion and preventing high temperature cracks can be adopted for welding.

Description

technical field [0001] The present invention relates to welding systems and welding methods. Background technique [0002] An industrial robot such as a welding robot that performs welding is supplied with teaching data and operates so as to execute the work set by the teaching data. The teaching data is constituted as a set of, for example, a program file that describes an operation to be performed by the robot, and a data file that describes data such as various conditions. Then, by combining these files, the welding robot is made to perform a desired work. [0003] As a method of setting various conditions for causing a welding robot to perform a desired operation, for example, Patent Document 1 describes an automatic welding method in which the cross-sectional shape of the welded joint perpendicular to the welding line is measured, and the The obtained cross-sectional shape of the welded joint is used to obtain the size of the gap and the center position of the gap in ...
