Key Points for八角管 Welding

Ensure water, electricity, and gas connections are secure and properly connected as per requirements; no loose connections allowed. Water, electricity, and gas are all hazardous factors in the eight-angle pipe welding process, so thorough checks must be conducted before welding.

2. Utilize relevant tools to clean the base material surface, such as brushes or sandpaper, to remove water, oil, oxides, and other impurities from the base material, ensuring welding quality.

3. Ensure the cleaning of the eight-angle tube welding work site; no flammable or explosive materials are allowed, and wind-avoidance measures must be taken.

4. Carefully inspect the welding machine's wiring to ensure it meets requirements. Issues with wire quality are a common cause of accidents, so it's crucial not to take it lightly.

5. Pre-weld inspection of the octagonal tube material is crucial, as it directly affects the welding outcome, making it an essential step.

6. Critical welding structures must be cleaned using chemical cleaning methods. Simply use acetone or caustic soda sulfuric acid to remove surface contaminants such as water, oil, high melting point oxides, and oxides.
