PURPOSE:To shorten the time of a welding treatment and to reduce the defect of the welding, by putting a metal material having roughly the same shape as that of a cavity in the cavity formed at the welding part of a molding, setting the molding in a high frequency welder, and welding the moldings together by charging a high frequency electric current, and heating the above described metal material at a specified temp. CONSTITUTION:In welding parts 1c of a lower material 1a and an upper material 1b of which an elastomeric molding 1 to be welded is constituted, cavities 1d are formed respectively. Thereafter, an iron ring 2 is put in the cavity 1d formed in the above described lower material 1a and the upper material 1b to be welded is applied thereon from the upper side. They are set in a bottom force 3a of a high frequency welder 3. Then, a top force 3b is lowered and a predetermined high frequency wave is irradiated from a high frequency guide coil 3c to heat the iron ring 2 while a specified pressure is being applied on the elastomeric molding 1. When the iron ring 2 is heated at a constant temp., the inner circumference of the cavity 1d is melted and fused. The lower material 1a and the upper material 1b of which the elastomeric molding 1 is constituted are thereby surely welded in a body. |
