Hi, new to the gang - Bangalore, India
 

just real mind blowing.........
guys trying to adopt this plan to build a mig welding bot......what do u guys think.can i try..........

Welcome Anil!

Not being familiar with a mig welding bot, can you tell us how it will be different to a board-cutting CNC router table?

The first things that come to my mind is that you will want a 4th axis to rotate the mig "gun", and that the electrical noise could be an issue.....

Once you got the 4th axis setup and the noise/grounding issue "resolved", do you have a CAM package in mind for that very particular process?

Maybe you can configure one of those 5 axis robot arm CAM software...? I'm not very familiar with 5 axis CAM...

Feed speed and tip height is critical in MIG welding... robot quality weld that is... not that some human hand aren't capable of very good looking weld...

I think it's very feasible but the tricky part is the toolpathing (CAM) part; if you get it up and running, I (we) want to see it! Thanks in advance and keep us post on your project.

I don't think the noise/grounding is any worse than a plasma cutter, and the MechMate style motors/wiring/BOB's are often used for plasma cutters.

A lot of robot welding is boring old 2D stuff, and I see no problem to do that

thanks all of u for the inputs....will post my plans shortly coz i'll have to sit on my drawing board for now.

any more usefull tips would be of great help....
looking forward for it
thanks guys
