It is an example of the joining method described in 2-238072. FIG.
Since the face sheets 2a, 2b and 2a ', 2b' are likely to be distorted when joining the honeycomb cores 3, the dimensional accuracy is poor and the plate thickness is thin. When 2a and 2a 'and 2b and 2b' in FIG. 9 (A) are joined, the honeycomb panel is joined. However, butt welding such as 2a and 2a 'has a small thickness and dimensions such as 2a and 2a'. Not easy due to poor accuracy.

瑣である。In FIG. 9B, an insert material 4 having a height larger than the thickness of the honeycomb panel is sandwiched, and 2a and 2a 'and 2b and 2b' are welded through the insert material 4. However, the method of FIG. 9B has a problem that sufficient bonding strength cannot be obtained because the bonding of the core is not performed and only the face sheet is bonded. In addition, the projecting insert 4 protrudes the joint portion and impairs the appearance. Furthermore, the process of inserting the insert material every time joining is complicated.

Welding is performed by irradiation with an energy beam, for example, a laser beam L. In the present invention, welding is performed from the bottom side of the wave groove using an energy beam whose irradiation condition is preselected, so that no welding mark is generated on the outer surface of the upper face sheet 2a. Although the welding is performed at one location in the figure, it is determined to be one location, two locations or three locations depending on the required strength of the honeycomb panel, and the welding mode may be determined by seam welding or pulse welding. Therefore, a honeycomb panel having a strong and beautiful surface can be manufactured. In the figure, reference numeral 6 denotes a joint between the upper face sheet 2a and the honeycomb core 3.

れたハニカムパネルの使用が可能になった。According to the present invention, it is easy to join the honeycomb panels to each other or to other members, and there is no problem that the conventional joining of the honeycomb panels does not provide sufficient strength and welding marks are formed on the surface of the honeycomb panel. In addition, a honeycomb panel is obtained in which a strong honeycomb panel is obtained by using the side plate and welding marks are not present on the surface of the honeycomb panel structure. As a result, it has become possible to use a honeycomb panel that is easier to assemble than the conventional one and has excellent corrosion resistance.
