Hi guys, I'm going to introduce a welding robot recently, as a newbie, I have a lot of questions, so a friend of mine recommended this to me. Yes, I've been diving for days and read some articles and advice, thanks a lot! But I still have a lot of questions！
I have a compactor frame that needs to be welded. It is about 3.5 meters long, 1 meter wide, and weighs about 1 ton.
I know that in the passenger car industry, they use a lot of Fanuc robots and Fornius CMT.
But my situation here is a little different. The thickness of the steel plate is at least 8mm, and the assembly tolerances are wide and unstable. Although I have been redesigning my welding fixture, I am not confident that the root clearance will be controlled within 2mm.
So I have to use the nozzle sensor and arc sensor to relocate the position of the weld?
I'm going to use a suspended 6-axis robot that is mounted on a 3-axis truss for wide range of motion, and the frame will also need a positioner, so I have a total of 10 axes. It's going to be a huge project, and I need to spend a lot of money on the truss and positioner, so the budget for the robot is limited.
Our integrator recommended me some models of robots and welders. The robot: IMG, FANUC, CLOOS ABB, and the power source: Fornius, Lincoln, CLOOS.
I know all of these brands are good at arc welding, but I don't know the difference between them, but the price varies greatly. Fanuc is a relatively cheap solution, and its robot body is very cheap, but I don't know how well it works with the Fronius power? CLOOS has both their own robot and power, will it be easier to operate? The price of IMG is very high, almost twice as much as other brands, I don't know where their advantage is.
I know there are many guys here who have had many years of experience with welding robots and I hope to get your advice.
Also thanks to Google Translate!
