Description

Arc welding protective cover for vertical surface welding

Technical Field

The utility model belongs to the electric arc welding field, specifically speaking relate to an electric arc welding protection casing for vertical plane welding.

Background

Arc welding is the most basic welding method in fusion welding, and the simplest and most common method is arc welding in which welding is performed by a manually operated welding rod, which is called manual arc welding and is called manual arc welding for short. The manual arc welding equipment is simple, convenient and flexible to operate and high in adaptability. The welding process of manual arc welding: firstly, two electrodes at the output end of the electric welding machine are respectively connected with a weldment and a welding tongs, and then the welding tongs are used for clamping an electric welding rod. When welding, electric arc is led out between the welding rod and the weldment, and the end of the welding rod and the weldment are locally melted by the high-temperature electric arc to form a molten pool. Then, the molten pool is rapidly cooled and solidified to form a welding seam, so that the two separated welding parts are firmly connected into a whole.

In the welding process, the user often holds a mask or wears a helmet to protect eyes and the face from metal splashing during welding, and meanwhile, the welder also needs to wear shoes and trousers for preventing high-temperature scalding because the most easily scalded parts of feet and legs are formed by falling welding slag. However, the shielding tool directly close to the face is too heavy, is inconvenient for welders to perform welding operation, has large volume and higher cost, is not small enough, and cannot perform safety protection on surrounding staff without holding a mask or wearing a helmet.
