For minor damage like small cracks, you can have the frame repaired by welding. If the frame is rusted and rotten, it can be repaired with electric welding, and reinforced with a steel rod or angle iron. However, be aware that electric welding is not very durable and can easily break again. For a stronger and more durable repair, CO2 welding or argon-fluorinated welding is better. The repair cost is generally 80 to 100 yuan. For example, on a four-wheeled electric vehicle, the front frame is reinforced by welding under the steering gear and at the corners of the frame.
If the frame is broken, the repair method depends on the severity and location of the break. Minor breaks not in a major load-bearing area can be repaired by welding. First, clean the rust and dirt from the break, then weld, and check the strength and stability of the weld. Severe breaks or breaks in a major load-bearing area require replacing the entire frame.
If you lack relevant experience, it's best to seek help from a professional to avoid further damage or safety hazards.
To prevent frame breakage, regularly check the frame condition and avoid overloading and excessive impact. When buying an electric scooter, choose a high-quality frame made of sturdy materials. Regularly cleaning and lubricating the frame will extend its lifespan.
