摘要： In a multispot resistance welding machine, the electrodes (8,9) of which are fed with D.C. pulses from a rectifier unit (2) via two busbars (5,7) running across the welding machine, the busbars (5,7) are arranged on opposite sides of the plane of weld and the two poles (1,3) of the rectifier unit (2) are connected each to one of the opposite ends of the two busbars (5,7). The busbars (1,3) from the rectifier unit (2) are arranged parallel with the busbars (5,7) feeding the electrodes and the busbars (5,7) are at equal distances away from the centerline of the busbars (1,3) and are connected directly or via short leads to the electrides (8 and 9 resp.). Alternatively the two poles of a second rectifier unit arranged antisymmetrically with respect to the first rectifier unit on the opposite side of the plane of weld, are connected in parallel to the opposite ends of the two busbars.

摘要： The invention relates to multi-spot-welding machines for the production of lattice gratings suitable for use for example as walk ways, and which consist of upright flat bars parallel to one another and cross-bars welded transversely into these and again parallel to one another. The flat bars are usually fed intermittently to welding electrodes. The machine of the invention has at least one pair of cooperating electrodes which are aligned in the feed direction of the flat bars and spaced apart a distance substantially equal to the desired spacing of the cross-bars. The or each pair of electrodes is pressed in turn against each pair or cross-bars to be welded and the upright flat bars themselves act as current bridges between the electrodes of the or each pair. An abutment supports the flat bars against the force of the welding electrodes and this abutment has considerably greater hardness and wear resistance than the flat bar material. The abutment is of suitable design and is suitably positioned to correct the deformation of the longitudinal bars which occurs when the transverse members are welded thereon.
