This invention relates to a method for seamless welding of multi-cavity profiles and integrated molding of sound insulation layers, as well as a door and window frame. It belongs to the field of building door and window profile processing and manufacturing technology. By moving the injection of the sound insulation composite material before welding, pre-injection is completed when the profile cavity ports are open, solving the problem of material not flowing into the closed corner area and resulting in missing corner sound insulation filling in existing post-injection processes. By applying a heat-activated protective film to the welding end face and implementing a staged heating and pressurization process, the flow homogenization conditions of the molten material on the outer surface are improved, effectively reducing the width of the white weld seam at the corner. By selecting a sound insulation material system with a final curing temperature matching the welding residual heat temperature range, the residual heat during the natural cooling process of the corner after welding drives the final curing of the material, merging the welding process and the sound insulation layer molding process. No structural modifications to existing welding equipment are required, making it easy to promote and apply under existing production conditions.
