溶接ビード構造に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a welding bead portion formed by welding one surface of one plate with an end surface of the other plate and filleting both sides thereof in the vicinity of the end of the other plate. Regarding bead structure.

Are joined by forming fillet bead portion 3 by fillet welding, and so-called V winding welding is performed by performing so-called V winding welding so as to surround the end 2b of the mounting plate 2 from the end of the fillet bead portion 3. Was formed.

をかかえていた。However, this V winding welding is performed by manual welding of the operator, while the fillet welding forming the fillet bead portion 3 is automatically performed by the welding machine, and therefore a consistent total welding is performed. The automatic welding cannot be performed and the work efficiency of the welding is reduced, the welding technique with high difficulty that can be done only by a skilled welder is required, and the bead is not formed in the connection portion 4a with the automatic welding portion 3 and the V-turn portion 4b. The shape is likely to collapse and a welding defect is likely to occur. Further, since these portions are in a high stress portion near the end portion due to the presence of the mounting plate 2, cracks and the like are easily generated. There have been various problems such as the fact that a part needs to be grinded and requires a great deal of working time, and that it is difficult to apply the coating and surface treatment is required depending on the case.

生し易いという問題が解決されない。On the other hand, in order to partially solve the problem of V winding welding as described above, the fillet bead portion 3 is attached to the portion 2 of the mounting plate 2.
A welding method is also practiced, in which V winding welding is omitted by stopping before b and ending. However, with this method, the end of the weld bead, which is likely to cause defects, remains in the high stress portion of the end portion of the mounting plate 2, and therefore the problem that fatigue failure is likely to occur due to the defects cannot be solved.

However, such welding methods are limited to manual welding, stand-up welding is difficult in terms of welding technology, there is a weld end at a high stress point of the upper plate, and the plate joint is watertight. However, it has various problems such as not being used for welding internal structural parts such as tanks.

上工事が簡略化される。With such a weld bead structure, the base plate 1 and the mounting plate 2 can be fully automatically welded, and if automated, the welding work can be made extremely efficient and the fillet bead portion 3 can be welded.
Since there is no interruption or bead seam between the waste bead portion 5 and the waste bead portion 5, welding defects do not occur and high quality welding can be obtained. Further, since the weld toe does not exist at the stress concentrated portion or the high stress portion near the end 2b of the mounting plate 2 or in the vicinity thereof, fatigue fracture or the like is less likely to occur and long-life welding can be obtained. Furthermore, since it is a consistent automatic welding, there is no variation in the welding quality, and it is not necessary to finish the bead with a grinder or to perform a surface treatment, which simplifies the welding work and the grinder finishing work.

The difference is that an end weld bead portion 6 formed by additionally welding the base plate 1 and the end 2b of the mounting plate 2 is provided between the waste bead portions 5 and 5 on both sides. With such a structure, since the entire periphery of the contact portion between the base plate 1 and the mounting plate 2 is sealed by welding, a watertight structure in which water or liquid does not enter the contact surface. Therefore, this weld bead structure is used, for example, in the internal structure part of a water tank or an oil tank of a ship. Since the end weld bead portion 6 is a straight line weld between the discarded bead portions 5 and 5, it is a welding having a much lower degree of difficulty than the V winding welding, and can be performed even by an inexperienced welding operator. It is a thing. Further, since it is a straight line welding, there is a possibility of applying automatic welding.

In the hull structure of a ship, all of these weld bead structure parts are extremely large in number, and the total number is tens of thousands. Therefore, if the weld bead structure of the present invention is adopted, the work efficiency of hull construction is greatly improved, and labor saving and shortening of the construction period can be achieved. Further, stable high quality of the welded structure can be obtained.

寿命化が図られる。As described above, according to the present invention, in the invention of claim 1, a weld bead structure is formed by fillet welding a base plate which is one plate and a mounting plate which is the other plate.
The weld bead on both sides formed by fillet welding and the extended weld bead on both sides intentionally extended to the place where there is no mounting plate are welded, so the weld bead is continuous and its toe is It can be moved away from the edge of the other plate. As a result, there are no interrupted points or joints in the weld bead where defects are likely to occur, and welding quality is improved. Further, by moving the weld bead toe away from the end portion of the other plate, the stress concentration portion in the vicinity thereof, and the high stress portion, the stress in this portion where defects are likely to occur can be reduced. As a result, the condition for fatigue fracture is improved and the life of the welded part is extended.

一層顕著に発揮される。With the extension of the life of the end portion, it becomes unnecessary to finish the bead with a grinder to improve fatigue strength. Furthermore, since the weld bead portion and the extended weld bead portion can be consistently formed by automatic welding, the quality of welding is stabilized. In addition, since there is no need for manual welding such as the conventional V-winding welding and the need for grinder finishing, the welding work is greatly simplified, labor is saved, and the construction period is shortened. Particularly, in the hull structure of a ship, since there are innumerable fillet welded ends, the effects of the present invention as described above are more remarkably exhibited.

に、直線溶接であるから自動溶接適用の可能性もある。According to the third aspect of the present invention, since one plate and the end of the other plate are welded between the extended weld bead portions on both sides to form the end weld bead portion, the joint portion of both plates is joined. The entire circumference is sealed by welding, and the structure prevents water and liquid from entering the contact surfaces of both plates. As a result, the weld bead structure can be used, for example, in water tanks and oil tank parts of ships. In this case, this welding is a straight line welding between the extension welding bead portions, and is technically easier than conventional V winding welding. Therefore, the welding work can be facilitated and the welding time can be shortened. Further, since welding can be performed by an inexperienced worker, a skilled worker can be effectively utilized and the welding worker can be easily managed. Further, since it is straight line welding, there is a possibility of applying automatic welding.
