Projection welding nuts
Projection welding nuts
(OP)
I need to know what the force required for projection welding an M14 and M12 nut is. Is this something that could be done with air cylinders ,festo etc. As of now I am only familiar with projection welders that are stand alone wiht bowl feeder etc. I would like to incoperate this process within our current clamping welding procedure. Making it fully automated. Any information would be gratly appreciated.





RE: Projection welding nuts
As an example, for a TYPE EE piloted projection weld nut (6 projections), Property Class 10, the weld schedule would should look like this:
Electrode Force Weld Time Current
Newtons (Lbs) cycles K-amps
M12 (1.19 mm pilot) 6670 (1500) 11-13 22-24
(1.178 mm pilot) 8900 (2000) 16-20 23-25
M14 (1.19 mm pilot) 8900 (2000) 14-16 25-27
(1.78 mm pilot) 10680 (2400) 19-23 26-28
I guess everything is relative, but the forces aren't that high, though I don't claim to be an expert in pneumatic cylinders. Good luck with your project.
