The use of arc welding robots for automotive welding ensures stability and consistency in weld quality while reducing dependence on manual operation skills. However, the process generates significant smoke, spatter, and intense arc glare, which challenge maintaining a clean and safe production environment. Additionally, the arc glare and welding noise pose potential health risks to nearby workers. To address these issues, an aluminum profile arc welding room was constructed to effectively isolate and protect the robotic work area, enhancing both personnel safety and environmental control.
An arc welding room is not merely a single protective barrier; it consists of multiple components, including protective barriers, safety access passages, material entry/exit ports, maintenance openings, dust extraction equipment, and equipment support frames. When designing the overall layout, it is also essential to consider installation-related details such as material selection, sealing effectiveness, and protective performance. These factors directly impact the functional performance of the arc welding room.
(1) Material selection must address four key aspects: ease of construction, structural strength, material joining, and installation of sealing panels. In the BYD Xi'an automotive factory arc welding room project, 4040 and 4080 industrial aluminum profiles were selected as the main structural materials. The 4080 profiles provide the necessary strength and stability for sections with larger spans, while the groove design on the surface of the aluminum profiles facilitates the installation of sealing panels and ensures effective sealing.
(2) During operation, arc welding robots generate large amounts of dust, smoke, spatter, hazardous arc glare, and high-decibel noise, which can harm nearby workers. Therefore, the arc welding room must be highly sealed and equipped with dust extraction systems to promptly remove smoke and dust from the production area. For sealing materials, anti-glare acrylic panels can be used. These not only provide adequate lighting inside the welding room for monitoring equipment operation but also effectively block arc glare.
For safety access passages, anti-glare roll-up doors with safety locks are recommended. In areas with frequent material movement, flexible anti-glare curtain barriers can be installed for protection. For specific installation examples, refer to the aluminum profile arc welding room project at BYD's automotive factory.
