robotic welding

[Guido]

Hello everyone,

Does anyone have dimistics with the robotic welding process?

the question is placed because I would like to know if the robot and its electronics manage the distance of the torch from the component.

the torch runs a path that is that and only that?
What if the component is irregular compared to the path?
if the piece is moved to the torch, the latter collides (so that there are anti-collision devices) ?
if the piece is further away from the torch path, the piece is not welded?

I mean, carpenters aren't always the same as each other... how does it work?

Thank you.

Antillision is a mechanical device of release of the robot wrist. undoubtedly if the trajectory is one and the diphform mechanics will have problems. service solution with televamera with adaptive adjustment process.

the times I've seen making robotized welding I've always seen an operator testing all the movement and correcting the points that "cozzavano" (the software learned and memorized in real time corrections). We still talk about serial production, so the machine was not self-adapting. variations were managed as above, correcting the program

is called self learning

the problem is well known and solved in hundreds of different ways, depending on the type of welding, type of structure and type of series produced.
I would strongly advise you to turn to a supplement, or from the same supplier of the robot, at least the first time, to prevent the welding torch from tearing the structure.

However I can give you some input:

1. the anticollision device is not necessarily a mechanical release device. all robots have a software controlled and parameterized collision supervision.

2. self learning is used to record the basic path. If carpentry is a little different, with self-learning you don't make a snitch

3. There are welding dressings that correct the laying of the torch (understood as a Cartesian position and eulero trim) according to the current absorbed by the welder. this allows a constant welding cord.

4. Welding dressing also handles multi-pass and asymmetrical cyanphrine welds, which are the most ostical.

5. for large geometric variations of the piece are used optical tastators that correlate the position online (meaning only as a Cartesian position)

6. The cameras. .. let's leave them to be in the welding islands, it's not the most reliable solution and it's only used if there are no other systems.

If you ask more precise questions, you will have more precise answers
