Abstract

PURPOSE:To attempt to prevent a welding bar from occurrence of a lustrous dent by performing a welding through an insulating body placed between the welding bar and bodies to be welded when high-frequency welding is performed. CONSTITUTION:High-frequency welding is performed through an insulating body 3 placed between a welding bar 1 and bodies to be welded 2 and 2'. In this case, the insulating body 3 may be placed between the welding bar 1 and the bodies to be welded 2 and 2' on each welding or may be directly adhered on the welding bar 1 to improve the working efficiency. On the area of the surface of the bodies to be welded 2 and 2' with which the welding bar 1 is brought into contact, there is no fear that even patterns etc., formed on the surface of the bodies to be welded may be melted away due to high-frequency and ultrasonic energies, and a fastness of the welding can be obtd.

た。(Prior Art) Conventionally, when two sheets of synthetic resin, etc., used as interior materials for automobiles, are pasted together using high frequency and ultrasonic waves, patterns 9 are formed on the surfaces of the sheets, for example, When grains, etc. are directly applied with energy such as high frequency and ultrasonic waves, the grains disappear due to the impression of the welding bar on the surface, and the marks of the welding bar are left as a glossy surface, which is unsightly, so it is used on luxury cars etc. In some cases, in order to hide the fact that the material is synthetic resin, as a means to eliminate this gloss, we do not use a welding bar, but instead use adhesive to bond the area, and this work efficiency is extremely high. It was bad.

The areas where the welding bar (1) comes into contact with the surfaces of the objects to be welded (2) (2') are free from the possibility of penetrating the patterns formed on the surfaces of the objects by high frequency or ultrasonic energy (such as patterns formed on the surfaces of the objects to be welded). By using 8 pieces (with adhesive), it is possible to weld more firmly, and it is also possible to weld without leaving welding pressure marks or welding marks, or to eliminate the gloss of welding marks, and also to improve the appearance of decorative patterns. This has extremely beneficial effects such as gloss adjustment.
