The objective of this work was, to detect the emissions of CO, CO₂ and other components Keywords: air pollutionthat qualify air quality: Formaldehyde (HCHOC); Total volatiles (TVOC) and particulate matter (PM2.5 and PM10), which emanate from three electrical welding processes, most used in the repair of agricultural machinery: Shielded Metal Arc Welding (SMAW), Gas Metal Arc Welding (GMAW) and Gas tungsten arc welding (GTAW), using a fume hood or welding hood. For this purpose, a welding hood was designed and built using recycled materials from the “Universidad Nacional Agraria la Molina” (UNALM). The work was carried out in the welding workshop of the Department of Mechanization and Energy (D.M & E) of the Faculty of Agricultural Engineering of the UNALM. With the help of a detector device (Air Quality detector precision instrument), the readings of the 30 welded samples (ten for each process) were recorded, as well as the behavior of each of the processes with the Temperature and welding time. The readings were then evaluated with the statistical part. For which the Complete Random Design (DCA) with an Analysis of Variances (ANOVA) was used, which when interpreted in the discussions we came to the conclusion that the most appropriate weldable process for the conservation of air quality in almost all variable except temperature; was the one that uses a non-consumable GTAW tungsten electrode, better known as TIG (Tungsten Inert Gas) because it uses inert gas.
