I am working on a piece of railing that is aprox 75 years old, I am salvaging several pieces from the original section. They used brazing rod to form small collars at the base of the pickets. My question is can I weld the piket to my bottom rail, welding to the brazing, or should I grind the brazing off and weld to the steel picket. In all the welding i've ever done i've never ran into this situation.
