Argon arc welding is a commonly used welding method,widely employed in the fields of metal manufacturing and repair.Its characteristic feature lies in the use of inert gas(usually argon)during the welding process to shield against oxygen and other impurities,thus preventing contamination of the weld seam.Argon arc welding offers advantages such as high weld seam quality,fast welding speed,and minimal welding deformation,making it widely applicable across various industrial sectors.
However,argon arc welding also poses potential hazards,particularly to the health of welders.Firstly,the welding process generates significant ultraviolet radiation.Prolonged exposure to UV radiation can lead to skin inflammation,sunspots,and skin cancer.Therefore,welders should wear appropriate protective equipment such as goggles,protective clothing,and sunscreen to reduce the harmful effects of UV radiation during argon arc welding.
Secondly,the welding process produces harmful gases and fumes.Melting of the welding rod and workpiece at high temperatures releases harmful gases such as carbon monoxide,nitrogen oxides,and carcinogens.These harmful gases and fumes pose potential hazards to the respiratory system and overall health.Hence,welding should be conducted in well-ventilated environments,and respiratory protective equipment such as respirators or protective masks should be used to minimize inhalation of harmful gases.
To avoid prolonged exposure of welding workers to adverse welding environments,weld seam tracking technology has emerged.Argon arc welding can utilize automated welding techniques to achieve weld seam tracking,with automated welding systems typically comprising welding guns,sensors,control systems,and robots.Weld seam tracking sensors detect the shape and position information of the workpiece surface and feed this information back to the control system.Based on the feedback signals from the sensors,the control system controls the movement of the welding gun to achieve weld seam tracking.Robots can precisely control the position and speed of the welding gun,ensuring the quality and consistency of the weld seam.
In practical welding,welders need to accurately l
