1. Calculate the required length and quantity of angle iron according to the design requirements and purchase it. Select the appropriate angle steel specifications and welding materials according to the design requirements.
2. Make I-beam formwork according to the design requirements, and position and adjust the position of angle iron.
3. Cut the angle iron into the required length with a sawing machine or an electric hammer and process it.
4. Position the processed angle steel on the template according to the design requirements, and then assemble it. Fix the angle iron on the template with tools such as clips to ensure the accurate position.
5. Weld the angle iron with a welder. When welding, the welding temperature and time must be controlled to ensure the welding quality.
6, after the completion of welding, need to repair the weld and surface treatment. Use grinding machine and other tools to repair the weld and carry out surface treatment to ensure the flatness and beauty of the I-beam.
