Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of mooring chain welding, and particularly relates to a mooring chain welding machine with preheating tooling. BACKGROUND

[0002] Mooring chains are indispensable key components in important marine equipment such as ships, offshore platforms and port facilities, and are mainly used to fix the position of a ship or a platform. Mooring chains are usually made of high-strength steel, and the manufacturing process requires extremely high precision and quality to ensure that the mooring chains have good load-bearing capacity, corrosion resistance and wear resistance during use. In the manufacturing process of mooring chains, welding is one of the most critical processes. During welding, the welding site needs to have sufficient strength, toughness and corrosion resistance to ensure the long-term stable use of the mooring chain. In the process of welding the crosspieces in the middle of the mooring chain, the temperature change of the welding area and the contact of different materials can cause problems in the performance of the welded metal, especially when welding high-strength steel, the welding site is prone to cracks, welding defects and other problems, thereby affecting the welding quality and the overall performance of the mooring chain. Therefore, in order to improve the welding quality and avoid welding defects, preheating technology is used. In the welding process of high-strength steel, a large temperature difference at the welding site can cause cracks, stress concentration and other phenomena in the material during welding, affecting the welding quality. Preheating can effectively reduce the thermal gradient in the welding process, reduce the stress and thermal deformation generated during welding, prevent premature cooling of the material, and make the temperature of the welded metal and the base material closer, thereby reducing the risk of welding defects.
