Welding fumes from steel structures contain heavy metal dust such as Fe\u2082O\u2083, MnO, and CrO\u2083, as well as small amounts of toxic gases (such as ozone and nitrogen oxides). Long-term exposure can lead to pneumoconiosis and respiratory damage, and must meet the requirements of the “Integrated Emission Standard of Air Pollutants” (GB 16297). This article mainly introduces how to collect and purify welding fumes from steel structures.<\/p>\n\n\n\n

The core of its treatment is “high-efficiency capture + graded purification.” According to the welding scenario (fixed workstation\/mobile operation\/large components), fume concentration, and airflow requirements to sellect a suitable solution, as follows: Capture efficiency directly determines the subsequent purification effect. To avoid fume diffusion, we recommend combination of “source capture + overall ventilation”.<\/p>\n\n\n\n

1.Collect and Purify Welding Fumes From Steel Structures, Source Capture (applicable to over 90% of scenarios)<\/strong><\/strong><\/h2>\n\n\n\n

Precise capture at the welding point, reducing energy consumption. Common equipment: Welding fume extractor<\/a> (mobile\/fixed type). Applicable scenarios: manual arc welding, gas shielded welding, argon arc welding, etc., single\/multiple fixed workstations, on-site mobile operations (such as steel structure workshop installation, bridge welding).<\/p>\n\n\n\n

Core Structure:<\/strong> Suction arm (360\u00b0 rotatable, 2-3m long) + Collection hood (hood opening diameter 300-500mm) + Cartridge dust collector<\/p>\n\n\n\n

Key Parameters:<\/strong> Hood opening wind speed \u22651.5-2m\/s (to prevent smoke and dust escape), processing air volume 500-2000m\u00b3\/h (500-1000m\u00b3\/h for single workstation, 1500-3000m\u00b3\/h for multi-workstation operation).<\/p>\n\n\n\n

Advantages: <\/strong>Flexible mobility (mobile type with casters), easy installation, suitable for welding small and medium-sized components; the welding workbench can use fixed type, suitable for assembly line operations.<\/p>\n\n\n\n

2.Overall Ventilation (suitable for large-area diffusion scenarios) <\/strong><\/h2>\n\n\n\n

When source collection cannot meet the area (such as on-site welding of large steel components, outdoor operations), need overall ventilation to reduce the concentration of smoke and dust in the workshop.<\/p>\n\n\n\n

he workshop blowing and suction dust removal system uses a combination of blow wind and wind supply to create spatial airflow in the welding area.<\/p>\n\n\n\n
