Abstract: The present disclosure relates to electro-conduction devices and methods for submerged arc welding of straight-seam steel pipes and in particular to a lateral electro-conduction device and method for multi-wire submerged arc inner/outer welding of a straight-seam steel pipe. The present disclosure aims to overcome the problem of poor closing of the electromagnetic field resulting from the existing negative-pole electro-conduction mechanism and the problem of unstable welding process resulting from bending deformation in the steel pipe welding process.

Abstract: The disclosed apparatus comprises a computing array comprising a plurality of computing modules, wherein each computing module comprises at least one storage cell, a reset switch, and a capacitor; the storage cell comprises at least one storage switch, and the storage switch comprises a storage control terminal, a storage detection terminal, and a storage terminal, the storage control terminal to receive a storage state voltage to adjust the impedance characteristic between the storage detection terminal and the storage terminal; the reset switch comprises a reset control terminal, a reset detection terminal, and a reset terminal, the reset control terminal to receive a reset voltage and the reset terminal is used to receive a reset state voltage. The disclosed apparatus also comprises a control module, which is used to control the computing array to perform at least one of a store operation, a read operation, and a compute operation.
