Request 3D Model

Non-Piloted Nut Electrodes are for welding nuts. The part has an insulated, spring loaded pilot that retracts when it makes contact with the upper electrode which prevents damage.

A refractory metal face is made of RWMA Class 11 (75% tungsten, 25% copper) (ASTM 702 C1D) is brazed onto the base material. This face is typically used for welding at higher pressure and heat common with projection welding.

The overall length is 2.500 IN
The part mounts via a 5RW standard taper which is suitable for weld forces ranging between 800 to 1500 pounds of force.
The weld face is 0.625 IN
The part has a spring loaded insulated pilot for welding a #4 nut.
The diameter of the pin is 0.082 IN
The diameter of the pilot is 0.142 IN.
