Designing and Constructing Welding Tongs Equipped with Electric Arch and Ventilation System

Introduction: Considering disease and ill- effects occurrence due to gases inhalation and metallic vapors resulting from welding process with electric arch, we tried to design a device in this research in order to minimize the rate to which a worker is exposed to these adverse factors. Materials & Methods: Designing and constructing welding tongs apparatus with electric arch and ventilation system was fully innovative. It is composed of: main body, vacuum canal, driving canal, vacuum hood, special tongs, face - protecting shield and a wire connected to the tongs. Using this machine at the time of welding with electric arch, the worker can be protected from gases and metallic vapors produced by the welding operation. Findings: The designed apparatus was tested and constructed with defined abilities. This apparatus has been made in a way that meets the desired goal that is protecting workers against metallic smokes and other adverse factors resulting from welding operations. Discussion & Conclusion: The constructed apparatus was tested, according to the goals of the research, proving a good efficacy in protecting workers from being much affected by the produced gases and metallic vapors at the time of welding activities with electric arch. Because of inaccessibility to appropriate technology for manufacturing the apparatus, the prepared sample does not fully match the designed model which needs to be made using a more appropriate technology. More attempts are to be done to prepare the device in a more effective form.
