    摘要： A rod-based well screen is formed in place on a perforated pipe base by wrapping wire around the pipe base and a plurality of rods located around the outside of the pipe. The wire is welded sequentially to each individual rod as it is wrapped around the pipe. The welding and ground electrodes engage the wire and the rods respectively. The rod engaging ground electrode is positioned a short distance ahead of the wire being wrapped around the rods and the pipe base. The ground electrode includes a plurality of contacts. Each contact is mounted to pivot toward and away from a rod. Springs urge each contact toward a rod to hold the rod against the outside surface of the pipe base and to maintain good electrical contact between the contact and the rod. Each contact has a groove to guide the rod into position for welding to the wire.

    摘要翻译： 通过围绕管道基部缠绕线和围绕管的外侧的多个杆，在穿孔管基座上形成棒状井眼。 当线缠绕在管道上时，电线依次焊接到每个单独的杆上。 焊接和接地电极分别与导线和棒接合。 杆接合接地电极定位在电线周围的短距离处，绕着线和管基围绕。 接地电极包括多个触点。 每个触点被安装成朝向和远离一个杆枢转。 弹簧将每个接触件推向杆以将杆保持抵靠管座的外表面并且保持接触件和杆之间良好的电接触。 每个触点都有一个槽，用于将杆引导到焊接位置。

    摘要： An apparatus for manufacturing a wire wound filter screen from wrapping wrap wire over a set of rib wires has a frame, a spindle for supporting the rib wires in a longitudinal orientation, a wire guide for delivering wrap wire around the rib wires as the spindle rotates the rib wires, an electrode for welding the wrap wires to the rib wires at each intersection thereof, and a translating mechanism positioned on the frame for moving rib wires and the welded wrap wire longitudinal along the frame. A laser measures a gap between adjacent surfaces of wrap wire. A processor is used to adjust the translating of the rib wires relative to the gap. An air cushion urges the electrode against the wrap wire.
