激光制造在船舶制造中应用的国内外现状
 

   在20世纪90年代中期,激光作为一种重工业制造工具用于造船工业。大型舰船制造方法逐渐实现由铆接到焊接的变革,焊接方法、工艺和设备也稳步发展,从早先的气焊、电弧焊,发展到激光焊。


   造船技术的不断发展,带动了造船材料和船舶设计的重大变化。图1所示为造船工业中三明治夹层板的激光焊接。注册食品公司

    早期日本的一些船厂就使用激光切割设备获得了准确的切割尺寸和良好的切割质量,并从中受益。


   1992年,Vosper Thornycroft在欧洲船厂安装了第一台激光切割设备。90年代中、后期,欧洲船厂纷纷安装了用于焊接和切割的成套设备。在美国,Bender 船厂是第一家使用高功率激光切割设备的船厂。


   1999年Bender 使用6KW的Tanaka LMX Ⅲ激光器,在制造成本和质量上取得了巨大进步。


   2001年,联邦电动船部在其移动实验室安装了4KW的ESAB系统。激光切割设备在Bender的应用,引起了对发展高效激光焊接技术的关注。下面几个图为激光制造技术与系统在欧洲几个船厂的应用实例。

 

In the mid 1990s, the laser was used as a heavy industrial manufacturing tool for the shipbuilding industry. Manufacturing method of large scale ship gradually realize by riveting received welding changes, methods, processes and equipment, welding has been developing steadily, from the earlier gas welding, arc welding, to the development of laser welding.
The continuous development of shipbuilding technology has led to significant changes in shipbuilding materials and ship design. The laser welding of sandwich plates in shipbuilding industry is shown in Figure 1.

Some of the early Japanese shipyard used laser cutting equipment to obtain accurate cutting size and good cutting quality, and benefit from it.
In 1992, Thornycroft Vosper installed the first laser cutting equipment in the European yard. In the middle and late 90s, European yards were installed in a complete set of equipment for welding and cutting. In the United States, the Bender shipyard is the first shipyard to use high power laser cutting equipment.
1999 Bender using Tanaka LMX 6KW III laser, manufacturing costs and quality has made great progress.
In 2001, the federal motor ship Department installed ESAB's 4KW system in its mobile laboratory. The application of laser cutting equipment in Bender has attracted the attention of developing high efficiency laser welding technology. Here are some examples of the application of laser manufacturing technology and system in several European yards.
