Problems solved by technology

[0009] However, according to the linear oscillating device proposed in Korean Patent Application No. 10-2007-0030176, since several components including a stepping motor, a oscillating slideway, a motor driver and a controller need to be mounted on the welding carriage, the overall equipment increased weight and bulk
In addition, due to the weight of the motor and the swing slide, it is difficult to obtain the lateral balance of the welding carriage, so it is difficult for the welding operator to transport the welding carriage
Also, the welding carriage may flip over during the welding process
In addition, the multiplicity of wobble-related functions of the welded carriage increases manufacturing costs

Abstract

The present invention discloses a welding wire weaving apparatus for a submerged arc welding carriage, wherein the weight is reduced and operation is more convenient by means of mounting the apparatus in a space without prejudice to carriage operation when the welding wire being weaving. The welding wire weaving apparatus includes a truck running in a welding direction, a control panel controlling parameters required for welding and weaving operations, a welding wire reel mounting a welding wire thereon, a welding wire supplier supplying the welding wire to an upper part of a member to be welded, a weaver unit weaving the welding wire transversely, a supplier supporting shaft supporting the welding wire supplier at an upper part of the truck, and a weaver unit connection bar connecting the weaver unit to the supplier supporting shaft. The welding wire supplier includes a supply guiding roller, a compressive supplying roller, a welding wire guide bundle, a needle bearing, and an isolator.

Description

technical field [0001] The present invention relates to a welding wire swinging device for a submerged arc welding (SAW) carriage, in particular to a SAW sliding device that is installed in a space that does not hinder the operation of the carriage when the welding wire is swinging, reduces weight and improves operation convenience. The welding wire swing device of the frame. Background technique [0002] Typically, when welding two parent metals, the parent metals are spaced apart by a certain spacing, ie, a root gap of 4-12 mm, to facilitate the formation of the backside weld bead. In addition, in order to prevent the welded metal from being welded through, the backing material is connected to the rear surface of the parent metal, and the conductor wire is supplied between the parent metals. Therefore, the parent metal can be welded. [0003] When constructing the vessel, tubular arc welding (FCAW) and submerged arc welding (SAW) methods are commonly used. More specific...
