ABB Robot and Fronius Welder

plewandowski

Hello everyone, this is my first post here and I tried to find my answer here, but my approach was unsuccesful, so my question is:

I've got 2 ABB robots in multimove (2600 and 4600) - 2600 is carrying Fronius TransPuls Synergic 5000 welder (so we just use Welding Start/Welding Stop signals to operate), 4600 is rotating object to weld.

During work object rotation Weld gun is standing still and my question is - can I somehow use weaving move for welding robot without any further parametrization of weld data? Or should i just use MoveL commands to imitate weaving?

I don't think you can get weaving motion with static gun, I guess you have to use gun in motion in order to get weaving which might be a big problem since you have the other robot producing welding path.

Thanks for the response - i thought it might be possible, because I've seen that Cloos welding robots have possibility to weave when they're standing still or maybe it's just weaving imitation by doing simple move commands - sadly didn't have opportunity to look into source code.

Sadly I'm not welding technologist but I'll give it a try with put three points in loop during welding proccess - maybe that's the way i could achieve weaving-ish effect

Pardon the blank post above.

On a similar note can I have weaving motion without the use of an ArcStart command? We have a dumb welding machine (no DeviceNet) sitting on our robot for demonstration purposes, and we'd like to weave over a dynamic programmed path. The ArcStart command needs feed back from the welder even when the arc is disabled in ArcWare. So what I'm asking is there a solution using MoveL that can still use weave data or something like it?
