Problems solved by technology
Therefore, since the feeding speed of the welding wire 1 between times t3 and t4 is faster than the appropriate feeding speed corresponding to the welding current Iw, when switching to a direct current, a short circuit occurs and spatter occurs, sometimes not getting proper beading

Embodiment Construction
[0086] Embodiments of the invention will be described based on examples with reference to the drawings. figure 1 It is a figure which shows the arc welding apparatus of this invention. exist figure 1 Among them, a welding torch 7 is installed on the front end of the manipulator 5 of the welding robot 4, and a welding wire feeder 11 is installed on the upper arm 22 provided at the front end of the lower arm 21 of the manipulator 5. The welding wire feeder 11 and the welding torch 7 is provided with a welding wire feeding path changing machine 23. The wire feed path changing device 23 is attached to either the wire feeder 11 or the welding torch 7 via a flange. Regarding other functions, for and Figure 5 The same functions of the shown arc welding apparatuses are denoted by the same symbols and descriptions thereof are omitted.
[0087] Next, refer to figure 2 A first embodiment of the wire feed path changing machine 23 will be described. figure 2 It is a figure which ...

PROBLEM TO BE SOLVED: To provide arc welding equipment switchable of wire feeding speed of a welding wire 1, corresponding to a wire feeding speed set signal Fc. SOLUTION: The arc welding equipment repeats a first period when movement of a welding torch 7 is stopped and an arc 3 is generated between the welding wire 1 fed at first feeding speed and an object 2 to be welded, and a second period when the welding torch 7 is moved only by movement pitch and the arc 3 is generated between the welding wire 1 fed at second feeding speed slower than the first feeding speed and the object 2 to be welded. During the first period, a wire holding member 26 within a wire feeding route changing device 23 is positioned on a wire feeding straight line L interconnecting a wire insertion port 24 and a wire extraction port 25, and then, when the second period arrives, the wire holding member 26 is moved from the wire feeding straight line L to a separated position B. Then, when the first period arrives, the wire holding member 26 is moved onto the wire feeding straight line L. COPYRIGHT: (C)2012,JPO&INPIT
Description
technical field [0001] The present invention relates to arc welding apparatus for performing intermittent pulse welding methods. Background technique [0002] Figure 5 It is a configuration diagram of a general arc welding device. exist Figure 5 Among them, a welding torch 7 is attached to the tip of a manipulator 5 of a welding robot 4 , a welding wire 1 is fed from the welding torch 7 , and an arc 3 is generated between the tip of the welding wire 1 and an object 2 to be welded. A welding torch movement speed setting signal Uw and movement trajectory data Dw of the welding torch 7 are input from a teach pendant 8 to the robot controller 9 . [0003] The welding wire feeder 11 is attached to the manipulator 5, and the welding wire 1 drawn from the welding wire spool (not shown) is fed through the welding wire feeder 11, and the single wire connected between the welding wire feeder 11 and the welding torch 7 The coil bushing in the power cable 6 is guided so as to be fed...
