三明治[13-14]德国Meyer船厂与Web平台，广泛应用在豪华邮轮的甲板、舱壁、舱内的墙壁和楼梯的基础结构，与传统的蜂窝板加强筋板夹芯板焊接具有以下优点：[ 13 ] 1，质量可减少50%以上，占据空间可节约50%；2，噪声可降低80%，防震能力大大增强；3，从事碰撞，耐腐蚀，防火性能好；4，在高精度、高质量的生产车间，与传统加工方法相比可节省约30%小时的现场组装。
The ship is made up of many parts. It is suitable for the main parts of laser welded ship deck and bulkhead. Because of the deck and bulkhead, straight weld length and butt joint and T type joint, the laser welding is the first choice due to its appearance, welding distortion and welding plate material.
The application of ships in laser welding has made great changes in the design of the ship. Sandwich sandwich plate structure is a classic in structure design. Sandwiches can be divided into I, T, O, Z, x, etc., as shown in Figure four, depending on the different sandwiches.
Sandwich plate sandwich plate reinforcement refers to the welded plate in the two site, which is composed of a pile of laser welding welding technique of new equity, give full play to the characteristics of deep penetration laser welding, laser beam through the panel, and then melting close below the panel ", so complete the two parts are connected by welding, the basic principle is shown figure.
Sandwich [13-14] German Meyer shipyard and Web platform, the basic structure of the walls and stairs are widely used in luxury cruise decks, bulkheads, the reinforcement plate of sandwich panel with honeycomb plate of traditional welding has the following advantages:  1, the quality can be reduced by more than 50%, occupied space can be saved by 50%; 2. The noise can be reduced by 80%, shockproof ability greatly enhanced; 3, engaged in the collision, corrosion resistance, good fireproof performance; 4, the high precision and high quality production workshop, compared with the traditional processing method can save about 30% hours to assemble the scene.
