Abstract

PURPOSE:To easily make an end tab removable with its separation and to reduce the number of stages by providing a cut face in parallel to the base metal side face on the side face end part of the side facing to the base metal side face. CONSTITUTION:An end tab 1 makes a vertical face at its grooved face 2 as well as at its three other side faces and the upper face and lower face. A cut face 10 is formed in a parallel line to the base metal side face at the end part of the end tab side face 3 coming into contact with the base metal side face among them. The cut face 10 extends toward the grooved face 2 from the side face at the opposite side to the grooved face 2 and is the notching face completing at an adequate position, and yet penetrating the upper face and lower face respectively.

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a welding end tab, which is attached to the end of a joint weld line of a base metal when welding a base metal joint, and is easily separated after welding is completed. This invention relates to removable steel end tabs for welding.

(Prior art) Generally, when welding a joint by arc welding or the like with base materials to be joined facing each other, welding conditions tend to become unstable at the start and end of welding, resulting in various welding defects. Conventionally, welding has been carried out by attaching steel end tabs to both ends so that welding defects that are likely to occur can escape from the base metal.

In this case, before welding starts, the steel end tab is attached to the side surface of the base material by tacking or the like, and after welding is completed, the steel end tab is removed from the side surface of the base material by gas cutting or the like, and then the side surface of the base material is finished.

(Problem to be solved by the invention) However, since this steel end tab is welded to the base metal through the weld bead (welded metal) during welding, when removed from the base metal after welding is completed, There is a problem in that a large number of steps are required, such as removing the end portions so as not to damage them and taking into account the finishing work of the end surface portions of the base material after removal, and an extremely large amount of labor must be expended.

(Means for Solving the Problems) In order to achieve the above object, the present inventor focused on the fact that in the past, almost no revision measures had been considered regarding the shape and structure of steel end tabs, and developed a new shape. As a result of intensive research to create a steel end tab with this structure, we have created a shape and structure that maintains the same functionality as conventional steel end tabs, while also shortening the separation process.
The present invention was developed based on the discovery that a cut surface is formed in advance along the separation/removal line of the steel end tab.

That is, the steel end tab for welding according to the present invention is
For steel end tabs that are attached to the end of the joint weld line on the base metal, by providing a cut surface parallel to the side of the base metal on the side edge facing the side of the base metal, the base metal can be attached to the end of the joint weld line after welding is completed. The feature is that it can be easily separated and removed from the surface.

以下1本発明を実施例に基づいて詳細に説明する。The present invention will be explained in detail below based on examples.

As mentioned above, conventionally, when removing a steel end tab from the base metal after welding is completed, the entire steel end tab is not immediately separated from the base metal end, but a slight surplus is removed at the end of the base metal. Remove by gas cutting, etc., leaving behind
Thereafter, the remaining portion was ground away using a grinder, etc., and the end face of the base material was finished.

The present invention focuses on the steel end tab removal operation while leaving the above-mentioned surplus portion, and a cut surface is previously formed along the removal line.

となっているので、そのような煩雑な作業が不要となる
In this way, conventionally, when cutting along the removal line, it required skill to perform the initial cutting operation, but since the entrance of the pre-formed cut surface has already been cut, Such complicated work becomes unnecessary.

しかも、カット面が開先側に延在し、かつ、母材側面に
平行に線状に形成されているので、カット面長さに相当

Furthermore, since the cut surface extends toward the groove side and is formed linearly parallel to the side surface of the base material, subsequent cutting operations for a length corresponding to the length of the cut surface are unnecessary.

Therefore, the steel end tab can be easily removed by simply cutting the remainder of the cut surface and the bead portion parallel to the side surface of the base material (that is, along the cut surface).

After the steel end tab is removed by the above-mentioned removal operation, the cut surface is parallel to the side surface of the base material and is beautiful, so there is no need for finishing the end face of the base material as in the past. Even if finishing work is to be performed, it can be completed in a short time because only a small amount of cutting surfaces need to be finished slightly.

In addition, these are connected by spot welding 4 at appropriate locations to form a connected body. Spot welding location 4 is
It may be formed at one or more suitable locations, but it is not preferable to form it at least on the groove surface. When spot welding is performed at other locations, it is preferable to select a location where the end tab removal work can be easily performed and where consideration is given to prevent both end tab pieces from separating.1 For example, as shown in the figure, the top surface and rear side (bevel surface It is desirable to spot weld one spot on each side (on the opposite side).

(Effects of the Invention) As detailed above, according to the present invention, since the steel end tab is shaped with a cut surface, the end tab can be easily separated and removed after welding, reducing the number of steps by 1/2. This makes it possible to significantly reduce the amount as shown in 3. Furthermore,
Conventionally, the end tabs were cut and removed on site, which resulted in the cut surfaces becoming irregular.However, since the cut surfaces are pre-formed when the end tabs are manufactured, they can easily be made into flat and beautiful surfaces. In addition, since the end tab removal work only requires cutting on the extension line of the cut surface, the cut surface becomes regular, and therefore, it is possible to omit the finishing process of the end of the base material, which was conventionally performed. The number of steps can also be further reduced. Of course, the function as a steel end tab is the same as the conventional one, and there is no problem in welding work.
