Claims15
A method of making a stator comprising:
- positioning an inner tubular member having an inner surface within an outer tubular member, both the inner tubular member and the outer tubular member being formed from metal;
- installing a rigid mandrel within the inner tubular member;
- and
- applying a compressive force to the inner tubular member and the outer tubular member, the compressive force causing the inner tubular member to be connected to the outer tubular member.
