Welding is another critical step in the manufacturing process, where pieces are fused together to create a sturdy structure. Factories today have upgraded their welding techniques, utilizing robotic welders for consistency and strength. After assembly, the metal surfaces undergo cleaning and priming to prepare for painting, which protects against rust and enhances appearance. Finally, drawers are added, and the entire unit is subjected to quality control checks to ensure durability and functionality.
