Abstract: A system for submerged arc welding, having a container in which welding wire is stored so as to be available for welding, a welding torch, a guiding system for guiding the welding wire from the container towards the welding torch, and a feeder for moving the welding wire from the container through the guiding system towards the welding torch, the guiding system using at least one rolling element for guiding the welding wire. A method of operating a submerged arc welding system, wherein a first supply of welding wire and a second supply of welding wire are provided, the first and the second supplies each having a forward end and a rearward end, wherein the rearward end of the first supply is welded to the forward end of the second supply such that a weld is formed which can be fed through the submerged arc welding system.

Abstract: A retainer for a welding wire container has a base element and at least one upper element which rests on the base element. The base element has a central opening for allowing the welding wire to pass through, and at least two guiding openings through which holding fingers extend. The holding fingers are part of the upper element and are made from a flexible material.

Abstract: A flexible guide device for a welding wire, formed by a plurality of individual elements which are connected to each other in an articulated manner, characterized in that the individual elements are adapted to swivel in relation to each other in any direction.

Abstract: A cover (24) for a welding wire container (10, 12) has a body portion (26) provided with an elongate slot through which the welding wire (16) can be withdrawn from the container, and at least one flap (50) formed integrally therewith and partially defining the slot (32).

Abstract: A retainer for a welding wire coil has a plurality of fingers (38) and a base element (32) with an upper surface (34) and a lower surface (36), the fingers (38) extending downwardly beyond the lower surface (36) of the retainer (12).

Abstract: A cover for a welding wire container has a top side and a slot in the top side. The slot allows for welding wire to be pulled from a welding wire container. On the outside of the cover, a holding-down device is provided. The holding-down device is adapted to hold an end portion of the welding wire in flat contact with the cover.

Abstract: A cover (24) for a welding wire container (10,12) is shown, having an upper surface (26) provided with a slot (32) through which the welding wire (16) can be withdrawn from the container, and having spacing means (34) which define an inner portion (36) and an outer portion (38) of the slot such that welding wire extending through the inner portion of the slot is held spaced from welding wire extending through the outer portion of the slot.

Abstract: A reinforcement element (30) for a welding wire container is provided, having an elongated body (32) and an attachment provision (50; 52, 54, 56; 60) for being connected to a wall (16) of the welding wire container (10). Further, a welding wire container (10) having such reinforcement element (30) is provided.

Abstract: A container for welding wire comprises a box-like body having a bottom and a side wall, the side wall having a polygonal cross section with corners, and stabilizing elements arranged at at least some of the corners. The stabilizing elements extend upwardly from the bottom and have an outer shell portion comprising a corner portion facing the adjacent side wall and an inner portion facing an interior of the container for housing welding wire. The corner portion has a shape adapted to the shape of the adjacent corner. The inner portion defines a continuous inner wall.

Abstract: Container or box for packaging and unwinding a coil (18) of wire (2), which comprises: a box-like body (5, 11) that has a polygonal plan, can be opened at the top and is meant to accommodate a coil for wire; and a coil covering panel (16) that has a central circular opening (17) and a contour that matches the plan shape of the box-like body, so that it can freely descend within the box-like body in contact with the coil as the height of the coil decreases as the wire is unwound from above through the central opening of the panel, in order to prevent the lifting of turns of wire between the peripheral region of the panel and the container and thus the accidental entanglement of turns.
