The present invention relates to an improved welding structure and welding method. More specifically, the present invention relates to novel welding structures and welding methods that improve butt welding of wires or wires and the like.                         

Generally wires or wires (hereinafter collectively referred to as "wires". Thus, the term "wires" used in the present invention should be understood to refer to any metal member including wires, wires, etc. used for welding) Butt welding is mainly used to weld metals such as Such butt welding is performed by welding two wires requiring welding to each other, and then welding by current welding using contact resistance or arc welding using arc. However, in this butt welding, two wires must be kept in alignment, and this alignment state is liable to be disturbed during welding, which makes it difficult to easily weld. In addition, the use of a separate alignment tool is required to maintain the alignment of these wires.

On the other hand, when one wire to be welded is thick and the other wire is multi wire, or both wires are multi wires, the above-described current welding or arc welding method causes the multi wires to bend or open. It was not easy or could not get the desired weld. One method of the prior art to solve this problem is to use solder welding.

However, the above-mentioned soldering welding has a problem that not only is harmful to a human body but also causes environmental pollution by using lead.

The present invention is to solve the above problems of the prior art, according to a first aspect of the present invention, in the welding structure for welding the electric wire, the first wire; And a second wire, wherein one or both of the first wire and the second wire are bent in an L-shape, one of the first wire and the second wire is a thick wire, and the other is It is to provide a welding structure that is a multi-wire.

According to a second aspect of the present invention, there is provided a welding method for welding an electric wire, comprising the steps of: preparing a first electric wire; Preparing a second wire; Bending one or both of the first wire and the second wire into an L shape; And fusion bonding the first wire and the second wire by applying a current or an arc to the L-shaped wire, wherein one of the first wire and the second wire is a thick wire and the other Is to provide a welding method which is a multi-wire.

Further advantages of the present invention will become apparent from the following description with reference to the accompanying drawings in which like or like reference numerals designate like elements.

Hereinafter, the present invention will be described with reference to embodiments of the present invention.

1A is a diagram illustrating a butt welding method using current welding or arc welding according to the prior art. Specifically, as shown in FIG. 1A, when the two wires 10 and 10 'are to be welded, the welding is completed by performing current welding or arc welding using contact resistance after each end. However, in this butt welding, two wires must be kept in alignment, and this alignment state is liable to be disturbed during welding, which makes it difficult to easily weld. In addition, the use of a separate alignment tool (not shown) is required to maintain the alignment of these wires.

Figure 1b is a view showing a butt welding method using a prior art solder welding. Specifically, in the case where the one wire 10 is thick and the other wire is a thin multi wire 12, or both are multi wires 12 and 12 ', the current welding or arc welding method of FIG. 1A described above. When using the multi-wire bend or open during welding, welding is not easy, or desired welding was not obtained.

One method of the prior art for solving the above problem is to weld the thick wire 10 and the multi wire 12, or both wires 12 and 12 'by soldering. However, the above-mentioned soldering welding causes another problem not only harmful to the human body by using lead, but also causing environmental pollution.

2A, 2B and 2C show a new welding method according to an embodiment of the present invention, respectively.

As shown in FIG. 2A, either or both of the two wires 20, 20 'are bent into an L-shape and then the L-shaped portion is welded through conventional current welding or arc welding. In this case, the L-shaped bent wire portions 20, 20 'are melted and melted by an applied current or arc, so there is no need to align the two wires or use a separate alignment tool for such alignment. .

In addition, although FIG. 2A illustrates that the wire 20 is bent in an L shape, a person skilled in the art may understand that the wire 20 ′ may be bent in an L shape instead of the wire 20.

2B is similar to that of FIG. 2A, and either or both of the thick wires 20 and the multi-wires 22 are bent in an L shape, and then welding is performed by conventional current welding or arc welding. In this case, since the bent wire portions 20 and 22 are fused by melting with an applied current or arc, there is no need to align the thick wire and the multi wire or to use a separate alignment tool for such alignment.

2C is similar to that of FIGS. 2A and 2B, in which either or both of the multi-wires 22 and 22 'are bent in an L-shape and then welded through conventional current welding or arc welding. In this case, the bent multi-wire portions 22, 22 'are fused and melted by an applied current or arc, so there is no need to align the two multi-wires or use a separate alignment tool for such alignment.

The welding method of FIGS. 2A-2C described above is described in detail below.

Step 1: Prepare the first wires 20, 22.

Step 2: Prepare the second wires 20 ', 22, 22'.

Step 3: Bend either or both of the first wires 20, 22 and the second wires 20 ′, 22, 22 ′ in an L-shape.

Step 4: An electric current or an arc is applied to the L-shaped wires 20, 22; 20 ', 22, 22' to fuse the first wire and the second wire.

The first wires 20, 22 and the second wires 20 ′, 22, 22 ′ used in steps 1 and 2 may be thick wires or multi wires, respectively. Therefore, in the embodiment of the present invention, as shown in Figs. 2A to 2C, eight welding methods are possible.

The following effects are achieved when using the improved welding parameters and welding method of the present invention.

1. It is very easy to weld compared to the prior art, and it is not necessary to use a separate alignment tool to maintain the alignment of the wires.

2. No need to use lead soldering welding, no harm to human body, no pollution problem.

It is not. Therefore, the scope of the present invention should not be limited by the above-described exemplary embodiments, but should be defined only in accordance with the following claims and their equivalents.
