Abstract: An electric arc welding method is provided, wherein an electrode assembly comprises at least two fusible continuous electrodes acting on a workpiece for generating a weld pool via electric arcs, wherein the at least two electrodes are arranged in sequential order relative to a welding direction and laterally separated relative to each other, wherein steps are performed of monitoring at least one stability parameter (Stab_par) for each electrode of the electrode assembly; determining if one electrode of the electrode assembly violates a stability criterion (Crit); separating at least temporarily the one electrode violating the stability criterion (Crit) from one or more adjacent electrodes when a violation of the stability criterion (Crit) of the one electrode is detected.

Abstract: A welding device applies weld material between two work pieces such that the work pieces are connected mechanically with one another. The welding device includes a welding head and a central element. The welding head performs a welding action during transport thereof along an operating direction between the work pieces. Two primary sensor members are arranged on the central element upstream of the welding head relative to the operating direction. The sensor members register geometric properties of a spacing between the work pieces in which spacing the weld material is to be applied. Each sensor member is configured to maintain contact with a respective wall of the two work pieces adjoining the spacing while allowing variation of lateral distances between the central element and the adjoining wall. This is accomplished by the sensor members being pivotally attached to the central element via at least one pivoting axis oriented essentially perpendicular to the operating direction.

Abstract: A carriage for transport of a load, for example a load pallet, along a rail pair in a so-called deep racking store, has a carrier arrangement which, in a deactivated transport position, passes under a load resting on the rail pair. The carrier arrangement is disposed, in an activated lifting position, to carry the load from beneath so that it is free of the rail pair. The carriage has a supporting frame or chassis provided with at least four wheels. The carrier arrangement is rigidly connected to the frame or chassis and each wheel is journalled in an associated arm. The arm is pivotally journalled in the frame so as to be able to raise and lower the wheel in relation to the frame. The arm is operated by an operating device.

Abstract: A system for the deep racking storage of pallets includes at least one pair of rails which are intended for supporting pallets. The rails are of sufficient length to support several pallets. A carriage is positionable on a pair of rails and drivable therealong for moving the pallets. Each rail has an upper, longitudinal support surface and a lower, longitudinal rolling surface. The support surface is intended for supporting the pallets, while the rolling surface is intended for the carriage. On each rail, the support surface and the rolling surface are interconnected to one another by the intermediary of side walls. The side walls together form a space which tapers from above and downwards for aligning a carriage when this is lowered towards the rolling surface.
