Currently, the strapping work of steel production lines is mainly done manually. First, the steel strap is cut into a fixed length according to the bundle size, and then the steel strap is manually bent into the outer dimensions of the steel. The folded steel strap is put on the bundle material, and then four manual weldings are performed using an electric welder. The efficiency of the entire strapping work is very low.
