Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a welding electrode and a holding case,

The present invention relates to a welding electrode, and more particularly, to a welding electrode comprising a cylindrical core wire through which a welding current flows, a coating member covering the core wire, and a holder portion which is located at one end of the welding electrode, By bending and deforming so as not to be horizontal with the core wire, it is possible to improve the efficiency of welding work by increasing the convenience and accuracy of contact with the welding electrode by using a welding rod holder in a state of wearing a finger wearing glove or welding glove during welding And a welding rod storage case for facilitating the storage and use of the welding rod.

In general, welding techniques have been used to apply heat and pressure to the same or different kinds of metal materials to bond them directly to each other to form a direct bond between solids. In order to use the welding machine, the ground wire connected to the welding machine is brought into contact with the object to be welded, and the holder portion of the welding rod is attached to the welding rod holder connected to the welding machine, and the end of the welding portion, The welding is carried out while moving in contact with the object.

The constituent components of the coating include cellulose, titanium oxide, ferromanganese, silica, calcium carbonate, and an inorganic nitrile.

- Stabilize the arc.

- protects from the effects of atmospheric oxygen and nitrogen, and concentrates the arc at the weld.

- Protects the molten metal by creating a neutral or reducing atmosphere to prevent intrusion of oxygen and nitrogen in the atmosphere.

- Make slag with low melting point.

- A spatter with a small specific gravity and a good fluidity is produced to sufficiently cover the deposited metal to prevent oxidation and nitrification of the deposited metal.

- Add alloying elements to the deposited metal.

- Spatter is less than when uncoated, shortening the short-circuit time.

- Deoxidizing refining.

- Reduces the cooling and solidification rate of molten metal.

- Easy to weld special position.

- Easy to remove slag and make clean welding surface.

- dissolves and removes oxides on the surface of the base material and ensures welding.

- Less spattering.

- Prevent deterioration of the electrode during operation or during storage.

Because of the advantages of these coatings, most of the coated electrodes are used during welding, but the chemicals in the coatings dissolve by heat and generate harmful gases. In welding work, it is necessary to work in an environment exposed to harmful gas, high temperature, high pressure generated by covering of the welding rod. Therefore, in order to prevent a safety accident, the operator must have a secure welding dress. However, the thicker welded clothing reduces the efficiency of the work, especially when attempting to contact a welding rod with a conventional core wire and a horizontal holder portion placed on the floor using a finger or using a welding rod holder, So that it is very inconvenient. Moreover, since it is difficult to form contact between the electrode and the finger or the electrode holder, time is wasted for contact, which increases the time required for the welding operation and extremely lowers the welding workability.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art as described above, and it is an object of the present invention to provide a welding apparatus and a welding method capable of welding a welding rod and a welding rod, And the bottom surface of the holder is reduced, so that it is possible to easily form a satisfactory contact with the finger or the electrode holder even in the state of wearing the thick welding glove, thereby improving the efficiency of the welding work. And it is an object of the present invention to provide a welding rod storage case which facilitates storage and use of the welding rod.

In order to accomplish the above object, the present invention provides a welding rod and a storage case which are easily deformed by deforming the shape of the holder according to the present invention. The welding rod and the storage case have a cylindrical core wire through which welding current flows, And the holder part which is not coated with the coating agent is bent and deformed in a form that is not horizontal with the core wire so that the finger can be easily grasped during the welding work.

A welding electrode storage case for facilitating the storage and use of a welding electrode having a deformed shape of a holder includes a main body having a rectangular column shape with an opened upper surface, And a draw-out guide body formed with one or more needle-shaped drawing-out grooves for carrying out the draw-out guide, wherein a transport handle is integrally provided at one side of the main body, and the opened upper side is opened and closed by a cover.

According to the above-described method, the holder portion of the welding rod is bent and deformed so as not to be parallel to the core wire, so that even if the welding rod is on the bottom, a slight gap between the welding rod and the bottom is generated, Therefore, even in the state of wearing a thick welding glove, it is possible to easily form a satisfactory contact by using a finger or an electrode holder and to improve the efficiency of welding work,

When the holder part forms a very satisfactory contact between the deformed electrode and the finger or electrode holder, it is difficult for the conventional electrode to make a satisfactory contact with the finger or the electrode holder with the welding glove, The welding operation time can be shortened and the welding workability can be greatly improved.

Further, when the welding portion of the holder according to the present invention is contacted by a welding rod holder, the end portion of the holder portion is deformed when the welding portion is contacted with the welding portion, Thus, since one electrode can be used for a longer time, the number of times of replacement of the electrode can be reduced, so that the amount and cost of the electrode can be reduced, and the efficiency of the operation can be increased.

In addition, the welding rod storage case for holding the electrode rod bent and deformed by the holder part is provided with one or more welding rods each bent and deformed by the holder part in each of the needle-like forming grooves, so that the welding rod can be prevented from being tangled with each other, It is possible to increase the efficiency when the welding rod is brought into contact with the finger or the electrode holder in a state where the electrode is in contact with the electrode. In addition, it is easy to handle and an appropriate amount of electrodes can be carried separately, thereby preventing waste of unnecessary welding electrodes, thereby making it possible to create economic benefits, and to achieve a clean work environment, thereby improving workability and productivity.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood, however, that the appended drawings illustrate only the contents and scope of technology of the present invention, and the technical scope of the present invention is not limited thereto. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention based on these examples. These various modifications and changes will fall within the scope of the present invention described in the following description within the technical scope of the present invention.

A welding rod (1) according to the present invention includes a welding rod holder (1) which is bent in a manner to prevent the holder part from being horizontal with respect to a core wire, and which is connected to a power line 1, 2, and 3, a cylindrical core wire 2 through which a welding current flows, a coating member 3 covering the core wire, and a welding electrode (not shown) And a holder part 4 which is not covered with the coating material and is a handle part that can hold the electrode using a finger or the electrode holder.

1 shows a conventional welding electrode 1 according to the prior art in which the holder 4 is level with the core wire 1 so that when the welding electrode is placed on the floor during the welding operation, It is difficult to form a satisfactory contact with the finger or the electrode holder with the welding rod and the welding glove.

FIG. 2 shows a welding electrode 1 according to an embodiment of the present invention, in which the holder 4 is deformed in the form of a circle, and FIG. 3 shows a welding electrode 1 according to another embodiment of the present invention, 2 and 3, since the holder portion 4 is not horizontal with the core wire 1, the welding rod can be placed on the floor even when the welding operation is performed, A slight roll will reduce the contact surface between the electrode and the bottom surface, creating a very satisfactory contact between the electrode and the fingers or welding electrode holder with the welding glove.

When the holder is horizontal with the core wire, when the welding rod is placed on the floor, the contact surface is increased, and a thick welding glove is used. In case of using a finger or a welding rod holder, it is difficult to form satisfactory contact with the welding rod, The welding work time is increased, and the welding workability is decreased. In addition, since it is difficult to contact with the end part during welding, it is impossible to use the welding rod to the end, which increases the number of times of welding electrode replacement and wastes the usage amount and cost of the welding rod and reduces the working efficiency. I will.

Test Example . Measuring welding contact efficiency

30 persons (20 ~ 40years old) who were doing welding work were evaluated.

The conventional welding electrode and the holder portion according to the present invention, in which the welding electrode of the shape of "┌" and the welding electrode of the shape of "<" are respectively laid out on the floor, and the welding electrode holder is held by the hand with the welding glove- Table 1 shows the average number of electrodes that were contacted for 1 minute with a time of 1 minute.

division Conventional electrode The holder part is in the form of "┌" Electrodes in the form of "<" Fingers with welding gloves 16 35 34 Welding rod holder 12 33 30 Average 14 34 32

As shown in Table 1, as shown in Table 1, a welding electrode of the shape of the holder of the present invention and a welding electrode of the shape "" of the present invention were attached to a hand or glove with welding gloves , It was possible to contact more than twice the number of times during the same time when contacting with the electrode holder.

In addition, the welding rod storage case 11 according to the present invention is designed so that an operator can easily store and use the welding rod according to the present invention by preventing the welding rods bent and deformed from being tangled with each other. (13) formed with one or more needle-shaped forming depression grooves (13a) to be taken out to the outside in a state that one end of a welding rod is sandwiched between the main body (12) And a carrying handle 14 is integrally provided on one side of the main body, and the opened top surface is opened and closed by a cover 15. [

If the holder portion is bent and the shape of the electrode rod is deformed and stored in a general case other than the welding rod storing case according to the present invention, the welding rod may be mutually intertwined with each other and the welding rod may be worn. The welding electrode storage case should be used because it can be wasted on the floor and it may be difficult to maintain a clean working environment.

Currently, welding is used in all industries such as shipbuilding, machinery, automobiles, electricity, electronics, construction, etc., and the application range and materials of welding are becoming widespread day by day. In the modern society, resource saving and time are important in the contemporary society. In welding work, the conventional welding electrode is horizontally aligned with the core portion of the holder, so that it is difficult to contact with the welding glove. The welding time of the welding operation time is wasted. The welding electrode with the bent portion of the holder according to the present invention is easily contacted even in the state of wearing the welding gloves, so that the working efficiency is increased during the welding work and the working time can be shortened. It is possible to prevent the waste of the welding rod and to obtain the economic benefit, so that it can be used more easily in the places where the welding work is great.
