BIW Robotic Welding.

Hello everyone,


I was working on a small project, involving Robotic welding and pick and place. I have following queries.

  1. How do i model the 7th axis robot?
  2. In pick and place, how do i take into account change of gripper?
  3. How do i model change of gripper to weld-gun and 4 robots welding simultaneously on a part?

Thanks in advance. . . . .

Hi learner,


We had a similar question very recently.


We used Exporters or Workers to model the robots (1). The tasks (we called them operations) were modeled as normal material flow objects. Normally the cell controller follows a fixed sequence, so you can insert special operations for the tool changes as well (2). By having multiple material flow objects running simultaneously, you can use an Exporter/Worker for each of them (3). For visualisation you would of course change the relevant icons.


Let me know if you would like to test a special library for this, to speed up the modeling.

Hello Learner,


I have developed a complete library based on the transpoter and track. Like in this example: (little more complex in reality)


(it is just a transporter on a round track)


1. 7-Axis: if you need some kind of animation for the element: transporter on track, you can turn the icon in steps


2. with the P&P just calculate it into the tuning time,


3.  it is quite difficult with the P&P, you need to create a "material-flow". You can use the Target-control to run the process. Create all "positions" as SingleProcs and connect them with the P&P. In the target-control you set the destination after each step.


...with the transporter just drive to the position of the tool change/ welding and wait there for the processingtime.
