With the growing demand of the global shipbuilding industry, breakthroughs in laser technology are more suitable for shipbuilding requirements, and the upgrade of shipbuilding technology in the future will drive more high-power laser applications.
The world's water area accounts for more than 70%, and the possession of sea power means world hegemony. Most of the international trade is completed by sea. Therefore, major developed countries and economies attach great importance to the development of shipbuilding industry technology and market. The focus of the shipbuilding industry was initially in Europe, and then gradually shifted to Asia (especially China, Japan and South Korea). Asia seized the civilian merchant ship and freighter market, and Europe and the United States focused on the high-end shipbuilding market such as cruise ships and yachts.
In the past few years, the international trade freight capacity was excessive, the bidding for ocean freight and shipbuilding in various countries was fierce, and many companies were in a state of loss. However, COVID-19 swept the world, resulting in an unsmooth logistics supply chain, a decline in transportation capacity, and an increase in freight rates, which saved the shipbuilding industry. From 2019 to 2021, China's new ship orders increased by 110% to US$48.3 billion, and the scale of shipbuilding has jumped to the world's largest.
The modern shipbuilding industry needs to use a lot of steel. The thickness of the hull steel plate is from 10mm to 100mm. In recent years, the laser power has been greatly improved, and the laser cutting equipment has been upgraded from the kilowatt level a few years ago to more than 30,000 watts, which can be very good in cutting the thick steel plate of ships more than 40mm(S&A CWFL-30000 laser chiller can be using in cooling 30KW fiber laser). Laser cutting has higher precision and processing speed, and will become a new trend in the shipbuilding industry.
Compared with cutting, welding and tailor-welding of shipbuilding steel requires more labor and takes longer. Each component is assembled and formed mainly by welding. Many hull steel plates are welded by large-format components, which are very suitable for laser welding technology. Thick plates require very high laser power, and the 10,000-watt welding equipment can easily connect steel with a thickness of more than 10mm. It will gradually mature in the future and has broad application prospects in ship welding.
With the growing demand of the global shipbuilding industry, breakthroughs in laser technology are more suitable for shipbuilding requirements, and the upgrade of shipbuilding technology in the future will drive more high-power laser applications. With the development of laser applications, S&A chiller is also continuously developing and producing industrial chillers that meet the cooling needs of laser equipment, promoting the development of the laser chiller industry and even the laser industry.
