Benefits of technology

[0012]Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a weaving apparatus for a submerged arc welding (SAW) carriage, capable of being facilely operated by being reduced in weight and installed in a space not hindering the operation of a carriage.

Problems solved by technology

However, the LF still generates at the sidewall of the groove face due to a significant root gap between the parent metals.
Accordingly, it is still hard to reduce the number of SAW passes.
Furthermore, due to the weight of the motor and the weaving slide, it becomes difficult to achieve lateral balance of the welding carriage, accordingly making it hard for a welding operator to carry the welding carriage.
Moreover, a variety of weaving-related functions of the welding carriage cause increase of the manufacturing cost.

Abstract

A welding wire weaving apparatus for a submerged arc welding carriage 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, a welding wire guide bundle and an insulator formed between the needle bearing and the welding wire guide bundle.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a welding wire weaving apparatus for a submerged arc welding (SAW) carriage, and more particularly to a welding wire weaving apparatus for a SAW carriage, reduced in weight and improved in operational convenience by being installed at a space not hindering the operation of the carriage during weaving of the welding wire.[0003]2. Description of the Related Art[0004]Generally, when welding two parent metals, the parent metals are spaced by an interval, that is, a root gap of 4˜12 mm to facilitate formation of back weld beads. Additionally, to prevent generation of a burn-through from metal being welded, a backing material is attached to back surfaces of the parent metals, and a conductive welding wire is supplied between the parent metals. Thus, welding of the parent metals is enabled.[0005]When constructing a vessel, a Flux Cored Arc Welding (FCAW) method and a Submerged Arc Welding (SAW)...
