[0002] The welding and grinding station is a specific work area in industrial production used to process the surface of workpieces or welds after welding. It mainly undertakes tasks such as weld cleaning, excess weld weight removal, surface leveling, and polishing to ensure product appearance quality, dimensional accuracy, or to prepare for subsequent processes. The welding and grinding station is the core link of post-weld processing.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Welding and grinding are two key processes in metal manufacturing. The former focuses on material bonding, while the latter concentrates on surface finishing. They are often used together. Welding achieves structural connections between materials, while grinding improves geometric accuracy and appearance quality through surface finishing. In high-end manufacturing, the two form a close process chain: welding defects need to be repaired by grinding, and precision welding relies on grinding pretreatment.

[0027] Welding, also known as fusion welding, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure. Modern welding utilizes a variety of energy sources, including gas flames, electric arcs, lasers, electron beams, friction, and ultrasound. Besides its use in factories, welding can be performed in various environments, such as outdoors, underwater, and in space. Regardless of the location, welding can pose dangers to operators, so appropriate protective measures must be taken. Potential injuries from welding include burns, electric shock, vision impairment, inhalation of toxic fumes, and excessive ultraviolet radiation exposure.

[0028] Grinding, a crucial step in metal processing, is not only an inspection of preceding processes but also a control over overall quality. It plays an indispensable role in the parts manufacturing process, acting as the last line of defense to ensure a perfect product presentation. Metal grinding specifically refers to the mechanical treatment process performed on the weld area after welding. Its purpose is to remove welding defects, optimize surface quality, and improve structural performance. This includes removing residual weld slag, spatter, and high-temperature oxide layers to prevent corrosion and subsequent processing interference; smoothing out raised weld scars and excess weld weight; eliminating defects such as undercut and lack of fusion; reducing stress concentration risks; enhancing aesthetics; and achieving matte, brushed, or mirror-like finishes.

[0029] The welding and grinding station is a specific work area in industrial production used to process the surface of workpieces or welds after welding. It mainly undertakes tasks such as weld cleaning, removal of excess weld material, surface smoothing, and polishing to ensure product appearance quality, dimensional accuracy, or to prepare for subsequent processes. It removes the oxide layer, weld slag, or root defects from the weld surface, reducing weld filler and improving welding quality and efficiency. It also removes excess weld material, ensuring a smooth workpiece surface and preventing weld burrs from affecting assembly accuracy or causing safety hazards. The welding and grinding station is a core part of post-weld processing, using specialized equipment to optimize welds and achieve surface finishing. It is widely used in the automotive, pressure vessel, and steel structure industries. Its technological evolution is moving towards automation, flexibility, and integrated dust removal, balancing efficiency improvement with a safe working environment.

[0030] The welding and grinding station for small batches of parts is a flexible work unit designed for customized, multi-variety, and low-volume production needs. Its core features are flexibility, modularity, and rapid changeover capability. Through modular equipment, flexible tooling, and intelligent control technology, the small batch welding and grinding station solves the contradiction between efficiency and cost in multi-variety changeover, becoming the core production unit for customized manufacturing.

[0031] Welding fumes are a mixture of fine particles and gaseous pollutants produced during the welding process. They are mainly formed under the action of a high-temperature electric arc, where metal materials evaporate, oxidize, and condense into solid suspended particles. During welding, the high temperature causes the welding material and base material to vaporize. The vapors are rapidly oxidized and condensed in the air, and the resulting particulate matter mainly contains metal oxides such as iron oxide, silicon dioxide, and manganese dioxide. It is classified as a Group 1 carcinogen by the World Health Organization. Long-term exposure can lead to welder's pneumoconiosis or respiratory diseases.

[0032] Grinding dust is solid particulate matter generated during grinding or polishing operations. It is formed by mechanical force removing particles from the surface of materials. It has a wide range of particle sizes, is easily suspended and diffused into the air. Metal dust, as well as the abrasive itself, has a complex composition that depends on the type of material being processed. Metal dust is flammable and explosive, while silica dust can cause silicosis. Long-term inhalation can lead to respiratory diseases or occupational asthma, and there is a risk of combustion and explosion when the dust concentration is high.

[0033] Welding fumes and grinding dust can be synergistically purified through water treatment processes. However, differentiated solutions need to be designed based on the characteristics of different pollutants. Water purification can synergistically treat welding fumes, large particles and water-soluble gases, grinding dust, and non-reactive metals. However, reactive metal dust poses safety risks. Safety standards can be achieved through a combination of water spraying and high-efficiency filtration equipment.

The sewage outlet 19 can discharge the treated wastewater (a control valve can be connected to the sewage outlet 19. Opening the sewage outlet 19 can discharge impurities, and closing it can allow the air to re-enter the filtration and purification process).
