Can I weld to a clevis?

Clevis with cotter pin

Technically you should not weld to a clevis which is made of C1035 steel and has a carbon content of approximately 0.35%, too high to be normally considered a weldable material. If the engineer has required welding to the clevis, then a special welding procedure should be followed that is outlined in AWS D1.1 or designated by the engineer of record. An alternate option would be to use a jam nut against the clevis to lock the assembly in place.
