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： An electrode alignment device and weld head for automated welding machines includes a base member, a gap wheel, an electrode holder and a coupling rod. The gap wheel includes a plurality of graduations, where each graduation corresponds to a predetermined electrode spacing for an automated welding process. In one embodiment, the graduations in the gap wheel comprise pairs of apertures, with a first aperture for engaging an alignment post on the base member, and a second aperture for engaging an alignment post on the electrode holder. Among the graduations, the spacing between the first and second apertures is different. As such, the electrode spacing may easily and accurately be changed by disengaging the coupling rod, rotating the gap wheel to the proper graduation, and reengaging the coupling rod.
摘要翻译：用于自动焊接机的电极对准装置和焊头包括基座部件，间隙轮，电极夹持器和联接杆。间隙轮包括多个刻度，其中每个刻度对应于用于自动焊接过程的预定电极间距。在一个实施例中，间隙轮中的刻度包括成对的孔，其具有用于接合基座构件上的对准柱的第一孔和用于接合电极座上的对准柱的第二孔。在这些刻度中，第一和第二孔之间的间距是不同的。因此，通过使联接杆脱离，使间隙轮旋转到适当的刻度，并重新接合连接杆，可以容易且准确地改变电极间距。

摘要： A multiple spot welding machine suitable for the manufacture of welded wire mesh for concrete reinforcement has two pairs of bus bars supported on a transverse wall extending upwardly from a base plate of the machine. Two rows of transformers, for feeding the two pairs of bus bars, are arranged one on each side of the transverse wall. A number of electrodes are shiftable along the bus bars to any one of which each electrode is connectable. A vertically movable spring loaded bridging electrode is provided above the electrodes on the bus bars.
