摘要： Apparatus and method for forming a reinforcing cage for a prestressed concrete pile, in which the cage includes a set of main steel bars arranged in a circular pattern and an auxiliary wire which is helically wound around and welded at its crossings with the steel bars, that prevents any crossings from being welded when the current for welding is either insufficient in magnitude or not present and that prevents any unwelded crossings from being subsequently tempered.
