Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a stainless steel special-shaped steel welding device. Background Art

This utility model can place a variety of steel structures, and after the placement is completed, the welding position is exposed, and the welding position can be quickly spatially positioned, and two steel structures can be welded at the same time, with high welding efficiency and stable welding quality.

[0004] Although the above patent can quickly weld two steel structures, smoke will be generated at the welding head during the welding process. The smoke will spread in the air and cause harm to the health of the workers. To solve this problem, the current mainstream treatment solutions for welding smoke are suction and water precipitation. In specific operations, the smoke is sprayed with water to settle during the smoke extraction process. However, this method requires waiting for the floating smoke to fully contact with the sprayed water before it can be completely processed. The overall process is time-consuming and the operating efficiency is low. For this reason, the utility model provides a stainless steel special-shaped steel welding device. Utility Model Content
