Since its advent, laser technology has received widespread attention from the society and is known as one of the four great inventions of the 20th century. With the continuous development of the times, the application of laser technology has also been changing. In recent years, the power of lasers has been continuously improved, and its application has gradually penetrated into the field of heavy industrial manufacturing. In the Процесите на корабостроене, лазерно рязане, заваряване и почистване започнаха да заменят някои стари процеси, които оказаха определено влияние върху цялата корабостроителна индустрия . в момента, големи големи корабостроителници в Европа, САЩ и Япония приеха лазерна технология в голям мащаб .}
Прилагане на лазерно рязане в корабостроителната индустрия
The shipbuilding industry has very high requirements for the accuracy of hull segment transfer, and the gap of frame transfer must be controlled within 1mm. In the past, shipbuilding companies generally used plasma cutting to cut ribs. In order to ensure that the assembly gap meets the standard, a trimming allowance was set on the ribs, which required on-site manual trimming during on-site assembly. The quality of the trimming obtained was uneven. Manual trimming will cause residual oxides in the cut seam. At the same time, it also increases the workload of assembly and prolongs the assembly cycle, resulting in a significant extension of the entire segment construction cycle.
At present, in the shipbuilding industry, the main cutting methods for hull plate parts are flame cutting, plasma cutting, shearing and laser cutting. Compared with laser cutting, other cutting methods have many shortcomings, such as flame cutting and plasma cutting will lead to wide cutting seams, poor cutting accuracy, easy to produce harmful gases, and cause greater pollution to the environment. The marine steel plates cut by laser have good cutting quality, good verticality of the cutting surface, no slag, thin oxide layer, smooth surface, no secondary processing, can be directly welded, and have small thermal deformation and high curve cutting accuracy, which effectively reduces the coordination time and realizes barrier-free cutting of high-strength ship plates.
Още през 1992 г. корабостроителницата на Vosper Thornycroft беше първата, която използва оборудване за лазерно рязане в Европа . Оттогава корабостроителниците в европейските страни са инсталирали пълни набори оборудване за заваряване и рязане . в Съединените щати, Bender Shipyard е първата корабострои 6KW Tanaka LMX ⅲ Лазер и постигна голям напредък в производствените разходи и качество .
In recent years, "precision shipbuilding" and "fast shipbuilding" have become the main trends in the development of the shipbuilding industry, and laser cutting technology has developed rapidly. The shipbuilding industry mainly uses steel plates as raw materials. Using lasers to cut plates can replace some processing methods that require large mold punching, greatly shortening the production cycle and reducing Разходи за обработка . Използването на лазерни машини за рязане елиминира надбавките за сглобяване, елиминира явлението на ремонта на място и намалява, намалява трудните и плочи отпадъците, значително ускорява монтажа на рамката и значително подобрява качеството на сглобяването .
