Description

本発明は、各種機材、特に輸送機材の軽量化のために使用されるアルミニウム製ろう付けハニカムパネルを接合して大型の構造体とするためのハニカムパネルの摩擦接合方法に関する。   The present invention relates to a honeycomb panel friction joining method for joining a brazed aluminum panel made of aluminum, which is used to reduce the weight of various equipment, particularly transportation equipment, into a large structure.

各種機材の軽量化、特に輸送機材の軽量化は、燃料の使用量の削減を可能にし、直接環境保護につながるため積極的に進められており、各種機材へのアルミニウム及びその合金素材の使用が多くなっている。アルミニウム及びその合金素材は、軽量であると共に最適な断面形状、例えば、二面構造体により剛性を高くすることができ、平滑性にも優れているため、車両、船舶等の輸送機器用部材として好適である。   Reducing the weight of various equipment, especially the weight of transport equipment, has been actively promoted in order to reduce the amount of fuel used and lead directly to environmental protection. The use of aluminum and its alloy materials for various equipment has been promoted. It is increasing. Aluminum and its alloy material are lightweight and have an optimal cross-sectional shape, such as a two-sided structure, which can increase rigidity and is excellent in smoothness, so that it can be used as a member for transportation equipment such as vehicles and ships. Is preferred.

二面構造体には中空の押出形材やハニカムパネルがあるが、中空の押出形材は、アルミニウム合金を押出成形することにより作製されるため、成形できる形材の幅が限定される。一方、ハニカムパネルは、芯材のハニカムコアの周縁部に枠材を配置し、ハニカムコアの上下面に面板を配設して、この状態でろう付け炉に入れ、これらをろう付けし一体として作製されるため、ろう付け炉の大きさにより作製できるハニカムパネルの幅が限定される。   Although the two-sided structure includes a hollow extruded shape and a honeycomb panel, the hollow extruded shape is produced by extruding an aluminum alloy, so that the width of the shapeable shape is limited. On the other hand, in the honeycomb panel, a frame material is arranged at the peripheral edge of the honeycomb core of the core material, face plates are arranged on the upper and lower surfaces of the honeycomb core, and put into a brazing furnace in this state, and these are brazed and integrated. Therefore, the width of the honeycomb panel that can be manufactured is limited by the size of the brazing furnace.

従って、大型の構造体を製作する場合には、中空の押出形材やハニカムパネルの接合は必須となる。従来、その接合には強度面からアーク溶接（ＴＩＧ、ＭＩＧ）が適用されているが、溶接時の熱歪みによりアルミニウム合金材料が変形するという問題がある。外観を重視する部位では、アーク溶接時に形成される余盛りの削除が必要となる。更に、溶接時の多大な入熱による溶接部周辺の熱影響によって強度が低下し、その分構造体を厚肉に設計しなければならず、折角の軽量効果を減少させている。   Therefore, when manufacturing a large structure, it is essential to join a hollow extruded shape member or a honeycomb panel. Conventionally, arc welding (TIG, MIG) is applied to the joining from the viewpoint of strength, but there is a problem that the aluminum alloy material is deformed due to thermal strain during welding. It is necessary to delete the surplus formed at the time of arc welding at a part where the appearance is important. Furthermore, the strength is lowered due to the heat effect around the welded portion due to the great heat input during welding, and the structure must be designed to be thick accordingly, reducing the lightening effect of the corners.

車両用構造体には、６０００系（Ａｌ−Ｍｇ−Ｓｉ系）のアルミニウム合金の押出形材が最も多く使用されているが、通常の６０００系アルミニウム合金では、アーク溶接時の入熱により溶接熱影響部（ＨＡＺ）が軟化し、本来のアルミニウム合金押出形材の強度を大きく損ねる。また、アーク溶接特有のブローホールの発生や凝固割れ等の欠陥が生じることもあり、その手直しに溶接部をはつり、再溶接を行うため、多大の工数を要すると共に溶接部の外観も悪くなるという難点もある。   6000 series (Al-Mg-Si series) aluminum alloy extruded shapes are most often used for vehicle structures, but with ordinary 6000 series aluminum alloys, welding heat is increased by heat input during arc welding. The affected part (HAZ) is softened and the strength of the original aluminum alloy extruded shape is greatly impaired. In addition, defects such as the occurrence of blow holes and solidification cracks peculiar to arc welding may occur, and the welded part is reworked and re-welded, which requires a great deal of man-hours and the appearance of the welded part also deteriorates. There are also difficulties.

入熱が少なく、軟化や歪みの程度も少ない接合方式として、アルミニウム及びその合金製の形材の突き合わせ摩擦接合する方法が提案されている。（特許文献１参照）この方法によれば、中空の押出形材同士やハニカムパネル同士を接合した場合、その接合部位の変形が抑えられ、良好な接合を短時間で得ることが可能となる。ハニカムパネルにおいては、ろう付けにより組み立てられたハニカムパネル端部の枠材及び面板を突き合わせ、その突き合わせ面に沿って摩擦接合を行い、この方法で大型のハニカムパネルの製作が可能となる。
特開平９−３０９１６４号公報 As a joining method with less heat input and less softening and distortion, a method of butt-friction joining of aluminum and its alloy shape has been proposed. (See Patent Document 1) According to this method, when hollow extruded shapes or honeycomb panels are joined together, deformation of the joined portions is suppressed, and good joining can be obtained in a short time. In the honeycomb panel, the frame material and face plate at the end of the honeycomb panel assembled by brazing are butted together, and friction bonding is performed along the butted surface, whereby a large honeycomb panel can be manufactured by this method.
Japanese Patent Laid-Open No. 9-309164

アルミニウム及びその合金製の二面構造体同士を摩擦接合により接合することによって、従来のアーク溶接によって引き起こされる種々の不都合な点が解消できるが、例えば、ろう付け後のハニカムパネル同士を突き合わせた場合、隙間が生じることがあり、そのままの状態で摩擦接合を行うと、亀裂やトンネル状の穴が生成して、接合品質を著しく低下させる。   Various disadvantages caused by conventional arc welding can be eliminated by joining two-sided structures made of aluminum and its alloys by friction bonding. For example, when honeycomb panels after brazing are butted together In some cases, a gap may be formed, and if the friction bonding is performed as it is, a crack or a tunnel-like hole is generated, and the bonding quality is remarkably deteriorated.

隙間を生じる原因は、ろう付け加熱及び冷却の際、枠材が熱応力により曲がり、ハニカムパネルの端面にそりが生じるためであると推察され、更に、ろう付けにより、上記端面にろうの垂れが生じることがあるためと考えられる。さらに、ろう付けにより、アルミニウム材の表面に強固な酸化皮膜が形成され、その酸化皮膜が、摩擦接合の際、接合部に残り亀裂の原因になることもある。   The cause of the gap is presumably because the frame material is bent due to thermal stress during brazing heating and cooling, and warpage occurs at the end face of the honeycomb panel. This is thought to occur. Furthermore, a strong oxide film is formed on the surface of the aluminum material by brazing, and the oxide film may remain in the joint portion and cause cracks during friction welding.

本発明は、ろう付けハニカムパネルの摩擦接合で、ハニカムパネルの枠材がチャンネルであり、該チャンネルの凹部側が外方に向いているろう付けハニカムパネルの枠材同士を接合するものにおける上記従来の問題点を解消するためになされたものであり、その目的は、ろう付け後のハニカムパネル同士を突き合わせた際発生する隙間を極力押さえ、ろうの垂れや強固な酸化皮膜を除去し、接合品質が良く、しかも良好な仕上がりの摩擦接合を得ることができるハニカムパネルの摩擦接合方法を提供することにある。 The present invention relates to the above-described conventional method in which the frame material of the honeycomb panel is a channel, and the frame material of the brazed honeycomb panel in which the concave portion side of the channel faces outward in friction bonding of the brazed honeycomb panel . The purpose was to eliminate the problems, and the purpose was to minimize the gaps that occur when the honeycomb panels after brazing were put together, to remove brazing dripping and strong oxide film, and to improve the bonding quality. An object of the present invention is to provide a method for friction bonding of honeycomb panels, which is capable of obtaining good and excellent finished friction bonding.

上記の目的を達成するための請求項１によるハニカムパネルの摩擦接合方法は、ろう付け後のハニカムパネル同士を摩擦接合する方法において、ハニカムパネルの枠材がチャンネルであり、該チャンネルの凹部側が外方に向いているろう付けハニカムパネルの枠材同士を接合するものであって、ハニカムパネルの枠材の接合面を予め面削して平坦にすると共に、付着物を除去することを特徴とする。この構成では、枠材の接合面を面削して、隙間量を低減し、同時に接合面上の付着物を除去できるから、良好な摩擦接合ができる。また、この構成においては、面削が面板の側端及びチャンネルの側板の側端となり、突き合わせ後２か所を同時に摩擦接合できる。 In order to achieve the above object, the honeycomb panel friction bonding method according to claim 1 is a method of friction bonding the honeycomb panels after brazing, wherein the frame material of the honeycomb panel is a channel, and the recess side of the channel is outside. Write to be those joining the frame member to each other brazing honeycomb panel facing, in advance scalping the joint surface of the frame member of the honeycomb panel while flat, and removing deposits . In this configuration, the joint surface of the frame member is chamfered to reduce the amount of gaps, and at the same time, deposits on the joint surface can be removed, so that a good friction joint can be achieved. Further, in this configuration, the chamfering becomes the side edge of the face plate and the side edge of the side plate of the channel, and two places can be friction-joined simultaneously after the butting .

請求項２によるハニカムパネルの摩擦接合方法は、請求項１において、前記枠材の接合面はその凹凸が接合面長さ１ｍあたり少なくとも０．５ｍｍ以内となるまで面削されることを特徴とする。この構成では、枠材の接合面を突き合わせた際、凹凸が接合面長さ１ｍあたり少なくとも０．５ｍｍ以内であるから、この状態で摩擦接合しても、隙間が少ないので良好な摩擦接合が達成できる。 According to a second aspect of the present invention, there is provided the method for friction bonding of honeycomb panels according to the first aspect, wherein the joining surface of the frame member is chamfered until the unevenness is at least within 0.5 mm per 1 m of the joining surface length. . In this configuration, when the joining surfaces of the frame members are brought into contact with each other, the unevenness is at least 0.5 mm per 1 m of the joining surface length. it can.

請求項１の発明によれば、枠材の接合面を面削することにより、隙間量を低減し、同時に接合面上の付着物を除去できるから、良好な摩擦接合が可能となる。従って、ろう付け後のハニカムパネル同士を突き合わせた際発生する隙間がなく、ろうの垂れや強固な酸化皮膜が除去される結果、接合品質が良く、しかも良好な仕上がりの摩擦接合を得ることができるから、大型の構造物が少ない工数で製作出来、低価格化が図れる。また、面削が面板の側端及びチャンネルの側板の側端となり、突き合わせ後２か所の摩擦接合を同時に行うことができる。従って、上記の効果に加えて、２枚の面板につき同時に摩擦接合ができるため、工数削減が図れる。   According to the first aspect of the present invention, by chamfering the joint surface of the frame material, the gap amount can be reduced, and at the same time, the deposits on the joint surface can be removed. Therefore, there is no gap generated when the honeycomb panels after brazing are brought together, and the drooping of the brazing and the strong oxide film are removed. As a result, it is possible to obtain a friction joint with good joining quality and good finish. Therefore, large structures can be manufactured with less man-hours, and the cost can be reduced. Further, the chamfering becomes the side edge of the face plate and the side edge of the side plate of the channel, and the friction welding at two places after the butting can be performed simultaneously. Therefore, in addition to the above effects, the two face plates can be friction-bonded at the same time, so the number of man-hours can be reduced.

請求項２の発明によれば、枠材の接合面を突き合わせた際、凹凸が接合面長さ１ｍあたり少なくとも０．５ｍｍ以内であり、隙間が少ないので良好な摩擦接合ができる。従って、上記の効果に加えて、必要以上の面削や面削量不足を無くすことができる。 According to the second aspect of the present invention, when the joining surfaces of the frame members are brought into contact with each other, the unevenness is at least within 0.5 mm per 1 m of the joining surface length, and since there are few gaps, good friction joining can be performed. Therefore, in addition to the above effects, it is possible to eliminate unnecessary chamfering and deficiency of the chamfering amount.

以下、本発明の実施の形態を、本発明の前提となる技術態様を含め、図１〜９に基づいて詳述する。
図１は摩擦接合を適用するためのハニカムパネルの形態を示す斜視図、図２はハニカムパネルの製作状態を示す断面図である。図１、図２において、ハニカムパネル１は、芯材としてのハニカムコア２の周縁部３に枠材４を配置し、ハニカムコア２の上下面に面板５、５を配設して、この状態でろう付けし一体としてなる。 DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail based on FIGS .
FIG. 1 is a perspective view showing a form of a honeycomb panel for applying friction bonding, and FIG. 2 is a cross-sectional view showing a manufacturing state of the honeycomb panel. 1 and 2, the honeycomb panel 1 has a frame material 4 disposed on a peripheral portion 3 of a honeycomb core 2 as a core material, and face plates 5 and 5 are disposed on the upper and lower surfaces of the honeycomb core 2. It is brazed together.

すなわち、アルミニウム製ろう付けハニカムパネル１の場合には、アルミニウム（アルミニウム合金を含む、以下同じ）の箔又は薄板から形成されるハニカムコア２の周縁部３にアルミニウムの押出形材からなる枠材４を溶接により枠組みし、ハニカムコア２の上下面Ｐにはハニカムコア２と枠材４に対して重なる状態にアルミニウムのブレージングシートからなる面板５、５を載せ、治具でこれらを一体に固定してろう付け炉の中に入れ、ハニカムコア２と面板５、５との間、枠材４と面板５、５との間をろう付け一体とすることにより行われる。なお、ハニカムコア２と枠材４との間もハニカムコア２と面板５、５とから流動するろうによりろう付けされる。   That is, in the case of the aluminum brazed honeycomb panel 1, a frame material 4 made of an extruded aluminum material at the peripheral edge portion 3 of the honeycomb core 2 formed of an aluminum foil (including an aluminum alloy, the same applies hereinafter) or a thin plate. The face plates 5 and 5 made of an aluminum brazing sheet are placed on the upper and lower surfaces P of the honeycomb core 2 so as to overlap the honeycomb core 2 and the frame material 4, and these are fixed integrally with a jig. It is carried out by putting it in a brazing furnace and brazing and integrating the honeycomb core 2 and the face plates 5 and 5 and the frame material 4 and the face plates 5 and 5 together. The honeycomb core 2 and the frame member 4 are also brazed by the brazing fluid flowing from the honeycomb core 2 and the face plates 5 and 5.

このように構成されたハニカムパネル１は、ろう付け加熱及び冷却の際、枠材４が熱応力により曲がり、そりが生じたり、図３に示すように、枠材４と面板５、５との間に段差１０が生じ、ハニカムパネル１同士を接合する際の接合面１１は、凹凸のある形状になっている。また、接合面１１には、図４に示すように、ろう付けの際に流動するろうの垂れ１２があり、その表面は通常強固な酸化皮膜に覆われている。このような状態のハニカムパネル１の接合面１１同士を突き合わせても、隙間だらけの状態となるし、摩擦接合しても強固な酸化皮膜が残り亀裂の原因になるから、図３の二点鎖線に示すように、面削して隙間を無くし、ろうの垂れ１２や強固な酸化皮膜を除去する。   In the honeycomb panel 1 configured as described above, when the brazing heating and cooling are performed, the frame member 4 bends due to thermal stress and warpage occurs, or, as shown in FIG. 3, the frame member 4 and the face plates 5 and 5 The level | step difference 10 arises between them, and the joining surface 11 at the time of joining the honeycomb panels 1 is a shape with an unevenness | corrugation. Further, as shown in FIG. 4, the joint surface 11 has a solder sag 12 that flows during brazing, and the surface thereof is usually covered with a strong oxide film. Even if the joining surfaces 11 of the honeycomb panel 1 in such a state are brought into contact with each other, a gap is formed, and even if friction joining is performed, a strong oxide film remains and causes cracks. As shown in FIG. 2, the surface is chamfered to eliminate the gap, and the dripping 12 and the strong oxide film are removed.

面削の程度は、ハニカムパネル１の接合面１１同士を突き合わせて隙間が全くない状態が理想であるが、ハニカムパネル１の接合面１１同士を突き合わせ、摩擦接合するため加圧拘束した際、図５に示すように接合面１１の長さαにおいて、１ｍあたりその凹凸が少なくとも０．５ｍｍ以内となる面削の程度が必要となる。凹凸が０．５ｍｍ以内というのは、数多くの実験に基づくもので、この範囲であれば、摩擦接合に支障を来たすことがない。凹凸が０．５ｍｍを越えると摩擦接合に支障を来す可能性が高くなる。   The degree of chamfering is ideal when the joining surfaces 11 of the honeycomb panel 1 are abutted to each other and there is no gap at all. However, when the joining surfaces 11 of the honeycomb panel 1 are abutted and frictionally joined to each other, As shown in FIG. 5, the length α of the joint surface 11 needs to be chamfered so that the unevenness per 1 m is at least within 0.5 mm. The irregularity within 0.5 mm is based on many experiments, and if it is within this range, there will be no hindrance to friction welding. If the unevenness exceeds 0.5 mm, there is a high possibility that the friction welding will be hindered.

面削したハニカムパネル１は、図６に示すように、その接合面１１同士を突き合わせ、治具（不図示）により加圧拘束する。その接合線に沿い摩擦接合工具１３の硬質なピン１４を高速回転させ接合面１１の一端に刺し込み、その接合線に沿い他端まで移動させることによって摩擦接合を行う。その後、ハニカムパネル１を裏返し、同じように摩擦接合すると、図７に示すように、接合部１５によりハニカムパネル１同士を接合することができる。   As shown in FIG. 6, the face-cut honeycomb panel 1 is brought into contact with each other and bonded to each other by a jig (not shown). Friction welding is performed by rotating the hard pin 14 of the friction welding tool 13 at a high speed along the joining line, inserting it into one end of the joining surface 11 and moving it to the other end along the joining line. Thereafter, when the honeycomb panels 1 are turned upside down and frictionally bonded in the same manner, the honeycomb panels 1 can be bonded to each other by the bonding portion 15 as shown in FIG.

図８は、前記の技術態様を前提とする本発明の実施形態として、角管状の枠材４に代えて、枠材としてチャンネル２１を適用し、このチャンネル２１の凹部２２側が外方に向いているハニカムパネル１ｂの摩擦接合方法を示すものである。すなわち、チャンネル２１は背板２３の両端に側板２４、２４を設けてなり、従って、面削が面板５の側端及びチャンネル２１の側板２４の側端となり、図示の摩擦接合工具１３ａを用いれば、突き合わせ後２か所の接合を同時に摩擦接合できる。 FIG. 8 shows an embodiment of the present invention based on the above technical aspect, in which a channel 21 is applied as a frame material in place of the rectangular tubular frame material 4, and the concave portion 22 side of the channel 21 faces outward. 1 shows a friction joining method of the honeycomb panel 1b . That is, the channel 21 is provided with the side plates 24 and 24 at both ends of the back plate 23. Therefore, the chamfering becomes the side end of the face plate 5 and the side end of the side plate 24 of the channel 21, and the friction welding tool 13a shown in the drawing is used. Then, the two joints can be friction-joined at the same time after the butting.

すなわち、この摩擦接合工具１３ａは、面板５及びチャンネル２１の側板２４の厚みｔ1 とほぼ同程度の長さｌ1 （ｔ1≒ｌ1 ）を有するピン２５の両端に、円盤２６、２７をほぼ平行に固着して糸巻型接合部２８を構成し、更に、軸２９を介して同構成の糸巻型接合部３０が取り付けられてなる。また、糸巻型接合部２８と３０との距離Ｌ1 は、２つの接合箇所間の距離Ｌ2 に等しい。 That is, the friction welding tool 13a has disks 26 and 27 at both ends of a pin 25 having a length l 1 (t 1 ≈l 1 ) that is substantially the same as the thickness t 1 of the face plate 5 and the side plate 24 of the channel 21. The pincushion joint 28 is fixed substantially in parallel, and a pincushion joint 30 having the same configuration is attached via a shaft 29. The distance L 1 between the pincushion joints 28 and 30 is equal to the distance L 2 between the two joints.

上記構成の摩擦接合工具１３ａを使用すれば、図９に示すように、裏当て治具が必要なくなり、糸巻型接合部２８及び３０がハニカムパネル１ａ及び１ａに追従して軸方向の振れが無くなり、ハニカムパネル１ａの２つの接合箇所を同時に摩擦接合することが可能となる。従って、一度の操作によってハニカムパネル１ｂ同士の接合が可能となり、接合前段取り、接合後処理も一度でよいことになる。 If the friction welding tool 13a having the above configuration is used, as shown in FIG. 9 , a backing jig is not required, and the pincushion type bonding portions 28 and 30 follow the honeycomb panels 1a and 1a and there is no axial vibration. Thus, it is possible to simultaneously friction-join the two joining portions of the honeycomb panel 1a. Accordingly, the honeycomb panels 1b can be joined to each other by a single operation, and the pre-joining setup and post-joining treatment can be performed once.

以下、本発明の前提技術の効果を確認するための実施形態および比較形態について説明する。
実施形態
図３に示す断面形状を持ち、面板（材質：６Ｎ０１）の厚さ２．５ｍｍ、枠材（材質：６０６３）の肉厚５ｍｍ、幅４０ｍｍ、パネル高さ１００ｍｍ、パネル長さ３０００ｍｍ（接合長さ）、ハニカムコア（材質：６Ｎ０１）の肉厚０．３ｍｍ、セルサイズ３０ｍｍのろう付け後のハニカムパネルの接合面を最大１．５ｍｍ面削した。なお、ろう付け後のハニカムパネルのパネル長さ３０００ｍｍの曲がりは最大１．３ｍｍであった（この測定は、母材を定盤上に固定し、置針式形状式測定装置にて、面削面を全長に渡り走査し、凹凸を記録することにより、行った。）。 Hereinafter, an embodiment and a comparative embodiment for confirming the effect of the prerequisite technology of the present invention will be described.
Embodiment having the cross-sectional shape shown in FIG. 3, the thickness of the face plate (material: 6N01) is 2.5 mm, the thickness of the frame material (material: 6063) is 5 mm, the width is 40 mm, the panel height is 100 mm, and the panel length is 3000 mm (joining) The joining surface of the honeycomb panel after brazing with a length of 0.3 mm and a honeycomb core (material: 6N01) having a thickness of 0.3 mm and a cell size of 30 mm was shaved up to 1.5 mm. In addition, the bending of the panel length of 3000 mm of the honeycomb panel after brazing was 1.3 mm at the maximum (this measurement was performed by fixing the base material on a surface plate and measuring the chamfered surface with a needle-type shape measuring device. This was done by scanning over the entire length and recording the irregularities.)

２枚のハニカムパネルの接合面を突き合わせ加圧拘束すると、その接合面の隙間は０．５ｍｍ以下となり、その状態で、ピンが直径５．０ｍｍ、長さ４．５ｍｍであり、円盤の直径が１０ｍｍの摩擦接合工具を１０００ｒｐｍで回転させ、３００ｍｍ／分の送り速度で接合線に沿って移動させて摩擦接合を行った。次いで、裏返しにして反対側を同じように摩擦接合した。その結果、接合部は、摩擦接合による誤差等の欠陥が無く、表面にも欠陥が無く、透過Ｘ線検査でも内部に欠陥が無いことが確認出来た。   When the joining surfaces of the two honeycomb panels are butted and restrained under pressure, the gap between the joining surfaces becomes 0.5 mm or less. In this state, the pin has a diameter of 5.0 mm and a length of 4.5 mm, and the disk has a diameter of A 10 mm friction welding tool was rotated at 1000 rpm and moved along the welding line at a feed rate of 300 mm / min for friction welding. Subsequently, the other side was friction-joined in the same way upside down. As a result, it was confirmed that the joint had no defects such as errors due to friction welding, no defects on the surface, and no internal defects in the transmission X-ray inspection.

比較形態
前記実施形態で得たろう付け後のハニカムパネルの接合面を突き合わせ、加圧拘束したが、その時の接合面の隙間は最大２．２ｍｍとなった。この状態で面削しないままで、前記実施形態と同じ条件で摩擦接合した。その結果、接合部には断続的に溝状の欠陥が見られ、表面上の欠陥がない部分でも接合部の金属が不足してトンネル状の欠陥が生じているのが認められた。 Comparison form
The joint surface of the honeycomb panel after brazing obtained in the above embodiment was butted and restrained by pressure, and the maximum gap between the joint surfaces at that time was 2.2 mm. Friction welding was performed under the same conditions as in the previous embodiment without chamfering in this state. As a result, it was confirmed that a groove-like defect was intermittently observed in the joint part, and a tunnel-like defect was generated due to a lack of metal in the joint part even in a part having no surface defect.
