Welding technology is a key technology in ship manufacturing and the development of shipbuilding industry. Welding working hours account for about 30%-40% of the total working hours for shipbuilding. The welding cost accounts for 30%-50% of the entire hull cost, Welding efficiency and welding quality will directly affect the production cycle, cost, and hull quality of ship manufacturing. The traditional welding process welding steel plate needs to be grooved and filled with solder to meet the welding requirements. The thicker the plate, the greater the bevel angle, it requires multiple processes to be fully welded. will be high solder cost,Long welding time ,Poor weld flatness and poor firmness for This process

The traditional process of beveling requires at least 5 processes such as plasma cutting, grinding, drilling, milling, and beveling. Transfer 4 times, 4-5 workers (positions) can be completed, it is time-consuming and inconsistent accuracy,Using a 10,000-watt welding machine, only need one person, no need to transfer, and high accuracy. It can be completed in one-third of the time of traditional craftsmanship, improve the quality and efficiency of manufacturing.
