An exemplary embodiment of wire wrap welding system generally includes a headstock; a bed; a bed mounted tailstock linearly moveable in relation to the headstock; a linear induction drive system adapted to move the tailstock; a linear encoder system having a series of position encoders disposed on the bed; a servomotor adapted to rotate a headstock mounted spindle; a welding system positioned on the headstock, a servomotor positioned on the tailstock and adapted to rotate a tailstock mounted spindle; and a control system. An exemplary embodiment of a method for controlling slot openings between wire segments in a wire wrap welding process generally includes controlling movement of a bed mounted tailstock in relation to the rate of rotation of a headstock mounted spindle, utilizing a linear induction drive system, a linear encoder system, and a control system.

Wire screen manufacturing system and method

An apparatus for manufacturing wire wrapped screens utilizing a wire and support ribs is provided. The apparatus employs welding pressure control, utilizing a welding device mounted on a support assembly, wherein the support assembly is moveable in relation to a mounting structure and the wire and support rib weld pieces. Welding pressure is determined by a force measurement device, and a control and feedback system adjusts pressure. Mechanical actuator cylinders mounted on the support assembly and the mounting structure provide load balance. A method for making wire wrapped screens is also provided.

Welding pressure control apparatus and method

In some embodiments, methods for securing a cylindrical screen jacket to a base pipe include heating the screen jacket to expand it so that its inner diameter becomes greater than the outer diameter of the base pipe, positioning the base pipe at least partially within the screen jacket and allowing the screen jacket to cool and contract, engaging the base pipe.
