What should we pay attention to when welding hot-dip galvanized square pipes?

Generally, when welding hot-dip galvanized square pipes, it is necessary to check whether the water, electricity, and gas are connected, and all connections must be made as required without loosening. Water, electricity, and gas are all dangerous factors during the welding process of galvanized square and rectangular pipes, so they must be checked before welding. The staff of hot-dip galvanized square pipe manufacturers should use relevant tools to clean the surface of the base material, that is, use brushes or sandpaper to completely remove water, oil, oxides and other impurities on the surface of the base material to ensure welding quality. Pay attention to the cleaning of the hot-dip galvanized square and rectangular pipe welding workplace, keep away from flammable and explosive materials, and take measures to avoid wind. Be sure to carefully check whether the wiring of the welding machine meets the requirements. Problems with wire quality are factors that can easily cause accidents, so you must not take it lightly. Pre-welding inspection of hot-dip galvanized square pipes is very necessary because it is directly related to the welding effect. Important welded structures should be cleaned using chemical cleaning methods. You can simply use acetone or caustic soda sulfuric acid to clean water, oil, high melting point oxide film, oxides and other contaminants on its surface.
