Example Embodiment

[0098] [Embodiment 2]

[0099]Next, a second embodiment of the invention will be described. In the second embodiment, the welding start point or the welding end point of each welding pass is indicated as point information on a plane orthogonal to the welding advancing direction, and displayed on the display unit 43 of the teaching pendant TP (see Figure 5 )superior. Then, the welding pass of the moving destination can be selected using this display. Hereinafter, the details will be described.

[0100] image 3 It is a figure which shows the welding start point in each welding pass by point information on the plane orthogonal to the welding advancing direction. This illustration shows how it is displayed on the display unit 43 of the teaching pendant TP. As shown in the figure, the workpiece W and the welding torch T are displayed imaginatively, and the welding start points (including figure 2 All welding start points of P2-1, P2-2, and P2-3 exemplified in ). The curve...

Abstract

When the motion of weld pass is determined in a multi-layer welding robot, the weld pass only can be selected by successively reaching to a teaching point, thereby greatly wasting a lot of time. The multi-layer welding device, based on a pre-teaching basic welding line (Ws) including a welding beginning point (P2-1) and a welding ending point (P3-1) and a displacement amount set relative to the basic welding line (Ws), generates all of N layers of welding passes, and performs the welding by moving a welding torch (T) based on the generated welding passes. When any one of the all of N layers of welding passes is selected by a demonstrator as a motion is determined, a robot control device calculates moving target positions (P2-2, P2-3 etc.) on the welding passes. Next, when moving signals are input, the welding torch (T) moves toward the calculated moving target positions. Because the welding passes to be determined to move can be selected immediately without the need for rewinding, the determination time of position gesture can be greatly reduced.

Description

technical field [0001] The present invention relates to a multilayer welding device that generates a desired number of welding passes by reflecting a predetermined offset on a taught basic welding line. Background technique [0002] Multi-layer welding refers to a welding construction method that repeatedly welds the joints of thick plate workpieces through multiple welding passes, and fills the grooves with weld passes, thereby performing the welding construction method. When the multilayer welding is realized by a teaching reproduction type robot, it is necessary to teach the teaching points to the robot, but the amount of work required to teach the teaching points for all the welding passes is enormous. Therefore, as shown in, for example, Patent Document 1, only the basic welding line of the first pass is taught, and after the second pass, a predetermined offset is added to each teaching point of the first pass. Automatically generate multiple weld passes, reducing teac...
