Advertising words laser welding machine is generally used in the manufacturing industry of metal advertising words. Advertising words are divided into metal advertising words and non-metal advertising words. Metal advertising characters are first cut into the required flat metal shape by laser cutting machine, and then the metal belt is bent into the shape of font frame by advertising character bending machine. The laser welding machine for advertising words welds the word frames and words together to form a bottomed cylinder. The height of the metal advertising frame varies from 15mm indoors to 100mm outdoors. The materials that can be welded by laser welding machine are: stainless steel, brass, galvanized sheet, tinplate, tinplate, cold-rolled sheet and so on. The selection of materials is mainly based on the grade of advertising words. Among related materials, stainless steel is easy to polish and brass is easy to electroplate, which belongs to high-grade advertising words. Generally used for interior decoration, places where the naked eye can directly see the production effect, such as the front desk, room number, signboard and other areas, belong to small and medium-sized decorative words. Other metal advertising words are generally used for outdoor large-scale advertising words. After welding, painting is used to prevent rust. Because it is not easy to see the fineness of production outdoors, it belongs to a slightly rough type. Non-metallic advertising words generally use plexiglass, plastic, particleboard, wood board, plywood and other materials. Narrow-band saw, CNC computer milling machine and CO2 laser cutting machine are used for processing, and non-metallic advertising words do not need laser welding.
