Applications of laser welding in shipbuilding industry

Since the advent of steel and in order to improve the structural efficiency over a simple flat panel design, shipbuilding has relied up arc welded frame stiffened panels for construction. It has been variously that for such structures 25 % of the man-hour used in construction used for re-work. In this paper, the development of laser welding, the features of laser sources for industrial processes were briefly introduced. The application of laser welding to the production of hull plates, corrugated core sandwich panels, fabricated structural shapes, and others for shipbuilding has been discussed, comparison between laser welding structural shapes and traditional rolled shapes was carried out, and the practical examples of laser welding products were shown. Based on literatures survey, it is suggested to develop the laser welding techniques for the domestic shipbuilding industry, and to produce laser welding products, especially laser but welding hull plate and corrugated core sandwich panels, and then to improve the competitive ability of domestic shipbuilding in the international market.
