After welding, carbon steel plates can form a structure with high strength and toughness. Carbon steel itself contains a certain amount of carbon element, which endows it with good strength performance. When multiple carbon steel plates are connected together through welding, structural components of various shapes and sizes can be constructed according to actual needs. In terms of mechanical manufacturing, such as manufacturing large industrial equipment frames, the welded carbon steel plate structure can resist various complex stresses generated during the operation of the equipment and ensure the normal operation of the equipment.
