During the cutting process, a large amount of dust, smoke, and aerosols are generated, which causes an environmental concern and poses a threat to the health of workers [80,81,82]. The amount of smoke and dust emitted by laser cutting is related to the cutting speed and the setting parameters of the cutting air pressure.
Welding and cutting smoke and fume extraction
Extraction Arms. The most effective solution for removing and mitigating welding fume is close or at-source extraction. The arms, sometimes called snorkels, vary in diameter and length, can be positioned from 6 – 15 inches from the welding fume generator and typically have an extraction volume of 500 – 1,000 CFM.

rocesses. Some of the most common types of welding are: arc welding, which includes "stick," or shielded metal arc welding (SMAW), the gas-shielded methods of metal inert gas (MIG) and tungsten inert gas (TIG), plasma arc welding (PAW) and submerged arc weld. ng (SAW). Other welding processes may use oxy-acetylene gas, electrical current ...
Chemical Suppression Technology of Open-Pit Mine Blasting Dust and Smoke
Blasting 1 m 3 ore rock needs foam consumption of 0.06–0.16 m 3. Foam dust removal technology is mostly used in areas with hot climates and water deficient. The dust reduction efficiency of covering the blast area with foam is up to 41.7%, and the ventilation time of open-pit mines can be reduced by 2/3–3/4.
The Environmental Impact: Sustainable Welding Practices in …
The process of welding generates metal fumes, both from the metals being welded, from the fillers being used, and from the fluxes or shielding gasses being used. These fumes, released into the environment, can lead to poisoning the air, land, and water, as well as people or animals in the area. The electricity used in welding has to …

Respiratory Exposure to Toxic Gases and Metal Fumes Produced by Welding Processes and Pulmonary Function Tests …
Introduction Compared with gases, noise, heat, and the ultraviolet radiation, fumes produced during the welding process have the most deleterious effects on the welders'' health. 1,2 Approximately, 500000 full-time employees are working in the US in the capacity of welding operators. 3 There are 5.5 million welding-related businesses in the …
Using dry filtration to capture plasma cutting fumes
The plasma cutting processes used to cut mild steel, stainless steel, and other metals generate fine particulate dust and fumes that can be harmful to workers, machinery, and electronics if not properly controlled. One solution is the use of dry downdraft tables (see Figure 1) with integrated dust and fume collectors and built-in ducts that …
Effects of Welding on Health I
Society to provide an assessment of current knowledge of the effects of welding on health, as well as to aid in the formulation of a research program in this area, as part of an ongoing program sponsored by the Com-mittee. Previous work has included studies of
Fume and gas emission during arc welding: Hazards and recommendation
Abstract. Welding is the principal industrial process used for joining metals, but at the same time, it''s the significant source of toxic fumes and gases emission. With the advent of new types of welding procedures and consumables, the number of welders exposed to welding fumes is growing constantly in spite of the mechanisation and ...
Keep your welding environment safe from harmful dust
Dust testing will tell you if your dust has a Kst and Pmax value — how much pressure an explosion will generate and how fast the explosion will travel. The data tells you how explosive your dust is and helps determine how to best mitigate the risk of …
FIRE PREVENTION DURING WELDING, CUTTING, AND …
tecting th. public from fire or life safety 269 changes. 271 270 h.Hot Work – Work involving welding, brazing, open flame soldering, heat treating, grinding, 272 thawing pipes, powder-driven fasteners, hot riveting, torch-applied roofing, or any other 273 process requiring use of a spark, flame, or. heat that.
Occupational Exposure to Welding Fume among Welders: …
In summary, the results of this study indicate that the welding fume generated during the welding process possesses a higher-than-normal level of manganese. Long-term, low-level exposure to the welding fume increases serum concentrations of manganese and iron and the blood concentration of lead, while it decreases serum zinc level among the career …
Evaluation on the Performance of the Ventilation and Dust Removal System in the Welding Plant | SpringerLink
Because of airflow characteristics, the airflow emerges from the ports and decays in the plant space. The airflow velocity is attenuated in the vertical height direction of the plant as shown in Fig. 2b, d, f, h.According to the standard Code for design of heating ventilation and air conditioning of welding operations plant [], the average air velocity in …
Welding Machine Smoke Exhaust System,Welding Fume Extractor, Dust …
1. Product description: Welding machine Fume Extraction System is a kind of dust and smoke extraction solution for automatic welding machines. It contains Dust Collector, ducts and suction room or hood. 2. Moland Product Series Moland Portable Fume Extractor series contain of MLWF50, MLWF70, MLWF100, MLWF360, MLWF120, MLWF200, MLWF280 …
Air Pollution in Welding Processes — Assessment and Control …
In welding processes, respirators should be selected in accordance with generated emissions, welding type, welding task, and working conditions. For example, NIOSH recommends a self-contained breathing apparatus for welding in confined spaces because the oxygen concentration in the space may be reduced due to welding.
Breathe easier: Mitigating welding hazards with ventilation and …
When it comes to welding, ventilation and exhaust is the most effective way to mitigate hazards caused by exposure. Most steels will generate iron oxide as a fume, which has a defined exposure limit. Different metals create different fumes. Metal coatings can also create fumes, like zinc oxide, which is created by welding galvanized steels.
