The main hazard arising from exposure to shielding gases is asphyxiation, usually stemming from accumulation of the gases in confined spaces. Shielding gases are supplied at a flow rate of around 15l/min in gas shielded welding processes and the gases may leak from connections in gas supply lines if these are not properly tightened.

Abstract During the arc welding process, many parameters must be taken into account to create the right joint. For this reason, the welding parameters are of partic-ular importance during the procedure. On the other hand, technologists only recently started focusing on dealing with the harmful effects that occur during welding.
Welding is a widely used process in various industries, but the resulting fumes can be hazardous to both welders and those working in the surrounding areas. The fumes
Welding can release harmful fumes and gases. These include ozone, carbon monoxide, and metal particles. They can harm health if not managed well. Adequate ventilation helps to dilute and remove these harmful substances. This reduces the risk of respiratory problems and metal fume fever. It also keeps the welder and others nearby safe.
Welding fumes and gases are by-products of welding processes and can pose significant health risks if not managed properly. These fumes consist of tiny metallic particles suspended in the air, while gases may include harmful substances like carbon monoxide, ozone, and nitrogen oxides.
Ozone is a health ris with Gas Metal Arc Welding 4 The number of particles and gases that is formed during the welding point is indicated by the emission value (discharge into the environment), i.e. the quantity produced per time unit. Emission values are given as ml/min for gases and mg/sec for particles. To

The present study was conducted to measure the exposure of welders to metal fumes and toxic gases produced during three welding processes and to evaluate the associated changes in their spirometry indices. The present cross-sectional study was conducted in 2018 in an Iranian shipbuilding industrial factory.
The major health hazards from welding among others are exposure to toxic fumes and Ultraviolet radiations. The health issues may be acute or chronic depending upon the type and duration of welding. Clinical reports indicated that the welders mainly suffered from respiratory disorders, skin malignancy and metal fume fever.
Health issues and health effects in welder. Welding fumes are a complex mixture of metallic oxides, fluorides and silicates generated by the evaporation and subsequent condensation of hot metal vapors during welding. The ultra-fine size of fume particles and CO are known causes of chronic disorder upon long term exposure .
A continuation of epidemiological studies to provide a better understanding of the role that welding fumes may play in immunosuppression, lung cancer development, neurotoxicity, skin damage, reproductive disorders, and other effects that some studies have associated with the components of welding fumes.
Various fumes and gases can be generated during welding. Welding fumes are metal-containing aerosols consisting of particles formed through complex vaporisation–condensation–oxidation processes during welding.
Released fume in welding, is a combination of various and fine particles such as carbon monoxide, silicates and so on. Welding fume analysis showed this fume is rich in toxic and hazardous compounds.
