[0022] See also Figure 3-4In this embodiment, the left and right ends of the goggles 201 are provided with extension platforms 203; the inner side of the extension platform 203 is installed with a rolling platform 204 for assisting the smooth movement of welding; the lower end of the rear baffle 202 is installed with left and right partition curtains 205; the inner sides of the extension platforms 203 on both sides are installed with rolling platforms 204, which can stably support the weldment during the welding process and assist the smooth movement of welding. The first cooling component 3 includes a cooling fan 301, a high-speed nozzle 302 and a multi-layer filtering structure 303; the lower end of the air supply pipe of the cooling fan 301 is installed with high-speed nozzles 302 distributed in parallel and equidistantly; the upper end of the cooling fan 301 is fixedly connected with a multi-layer filtering structure 303 for filtering dust and impurities in the introduced air; the cooling fan 301 introduces the outside air after filtering, and transmits high-speed cold air downward through multiple high-speed nozzles 302 to cool the welding workpiece, and the second cooling component 4 includes a water storage tank 401, a spring seat 402, a filter screen 40 3. Water pump 404 and atomizing nozzle 405; spring seats 402 with equal spacing are installed on the left side of the upper end of water tank 401; filter screen 403 is installed on the upper end of spring seat 402; filter screen 403 is hingedly connected to the right side of the upper end of water tank 401; atomizing nozzle 405 generates water mist, which absorbs and takes away the heat generated during welding and the welding slag and debris floating in the air, and floats downward with the air flow. A water pump is placed at the bottom of the inner side of water tank 401 404; an atomizing nozzle 405 is installed at the upper end of the water pump 404; when the water mist passes through the filter 403, the welding slag and debris contained in it can be filtered out and concentrated in the water storage tank 401, waiting for the water pump 404 to extract and form circulating water for reuse, and the downward airflow continuously blows the filter 403, and under the action of the lower end spring seat 402, the filter 403 is constantly shaking, which accelerates the discharge speed of the welding slag and debris at the upper end of the filter 403 into the slag discharge box 5.
[0023] When working, the first step is to put the weldment from one side of the seam welding machine body 1 between the two roller electrodes of the seam welding machine body 1. The roller electrodes pressurize the weldment and rotate it to perform seam welding on the weldment. During the welding process, the operator can intuitively see the internal welding situation through the goggles 201 of the protective structure 2. At the same time, the rear baffle 202 and the curtains 205 on both sides isolate the operating area into a small space to reduce the splashing of welding slag.

When the water mist passes through the filter 403, the welding slag and debris contained in it can be filtered out and concentrated in the water storage tank 401, waiting to be pumped out by the water pump 404 to form circulating water for reuse. The downward airflow continuously blows the filter 403. Under the action of the spring seat 402 at the lower end, the filter 403 continuously shakes, which accelerates the discharge speed of the welding slag and debris at the upper end of the filter 403 into the slag discharge box 5.
[0026] Through the above steps, the utility model can visually see the internal welding situation through the protective structure 2, and can prevent welding slag from splashing, thereby improving the operating safety of the operating staff. By starting the first cooling component 3 and the second cooling component 4 at the same time, the first cooling component 3 filters and imports the external air, and then transmits high-speed cold air downward, carrying water mist at the same time, to perform large-area air cooling and water cooling on the welding workpiece. The water mist absorbs and takes away the heat generated during the welding process and the welding slag and debris floating in the air. The air cooling uses the air flow to quickly reduce the temperature of the weldment and equipment, and after the second cooling component 4 floats downward, the welding slag and debris contained can be filtered out and concentrated in the water storage tank 401, waiting for the water pump 404 to extract and form circulating water for reuse, and the downward airflow continuously blows the filter screen 403. Under the action of the lower end spring seat 402, the filter screen 403 continuously shakes, which accelerates the discharge speed of the welding slag and debris at the upper end of the filter screen 403 into the slag discharge box 5. Such a dual cooling mechanism can greatly reduce welding deformation and defects.
