FIELD: process engineering.
SUBSTANCE: set of invention relates to method of welding obliquely cut frame sections for windows, doors, etc, and sealing tape used in said sections. Proposed method consists in that sealing tape from elastomer or elastic rubber material are secured in and/or on frame sections while obliquely cut frame section surfaces consisting of thermoplastic material are heated and melted. Frame sections with melted face surfaces are contracted till welding. Note here that sealing tapes are used that are not melted at frame section melt point. Parts of sealing tapes extending beyond frame section face surfaces in contraction and welding in oblique cut zone are pressed into frame section plane. Said sealing tape has sealing section and anchor section. Both said sections are made either from various hardness ethylene-propylene rubber, or anchor section consists of ethylene-propylene rubber while sealing section (N) is made from elastomer material with exposed or closed cells, or elastic rubber material. Soft material is placed on frame sections that is easily extruded by melted material.
EFFECT: better tightness in angular zones.
