Weld repair of product in CNC machines
Weld repair of product in CNC machines
(OP)
I am having trouble convincing the machining manager that weld repair of castings and forgings while still chucked up in CNC machines during machining is causing damage to the computer boards in the CNC machines. I think that the high freq electromagnetic pulse used to start the welding process is damaging the circuit cards in the CNC machines. I need some ammo to stop this practice. Can any one point me to the right source.
Thanks,

The first thing that I would do if you can not change the process is to install at least one (1) 8'x 1/2" UL listed ground rod within 5 feet of the machine. (Two rods might lower the ground resistance by 40%, 3 rods by 60%, and 4 by 70%, separate rods by 6ft.) Use # 4GA minimum welding cable for the ground leads. (I learned this the hard way.)
Here is a link to an article though not directly related to CNC machine, nor welding, does have some ammo for you.
