we are looking to add a automated spot weld center using turn table application requiring us to spot weld 3 brackets to housing 11 spot welds. my question is I received quotes for the centers one with Daihen/OTC/Nachi and another using Fanuc robots. I was told the Nachi would be better for the operation more speed and would be better overall for the application. can get any comments or recommendations on this .
NACHI is a fine robot with many options supporting spot welding. It shares it's robot controller design with our OTC DAIHEN robots. FANUC is also a fine robot. Is your application using an arm-mounted spot gun or are you carrying the part to the spot welders? That answer would likely change my recommendation significantly.
We integrate various robot brands and any welding robot will be really close for performance, speed accuracy etc. Are you spot welding using a MIG application or resistance welding. That will make a difference due to end of arm weight capacity.
