Abstract
因應人口增長以及生產製造業的蓬勃發展，無論是居住房屋或是廠房擴建的需求皆隨之提高，導致鋼構市場逐年成長，使2034年預期規模達1,800億美元。在此市場驅動力的作用下，再加上全球環保意識的抬頭，各國紛紛制定淨零碳排的政策，其中鋼構業更是首當其衝受到關注的產業之一。為此，雷射銲接新工法成為一項克服產能以及降低碳排放量的解決方案。工研院有感雷銲技術的重要性，邀請台大土木系團隊共同投入H型鋼雷射深銲模擬技術研究，在熔池形貌及銲後金屬晶粒成長模擬的準確度可達80%以上，能有效作為雷射銲接參數決策的初步依據。未來將持續深耕技術導入H型鋼雷銲生產線中，並擴充應用於箱柱型鋼構的製程開發上，以期翻轉傳統鋼構產品高耗能的生產方式，推動建材綠色製造與地球永續發展。
In response to population growth and the highly development of manufacturing industrial, there is a huge demand for housing and factory expanding. As a result, the steel structures market is expected to grow to 1.8 billion dollars in 2034. Besides, coupled with rising global environmental awareness and net zero carbon emission policies, the steel industry becomes one of the first areas that is focused. Thus, laser welding technology becomes the one of solutions to overcome capacity and carbon emissions problem. Base on the important of laser welding, ITRI has conducted research on H-beam steel laser welding processes and developed high-power laser deep penetration welding simulation technology with the team from department of civil engineering, National Taiwan University. It achieved 80% accuracy rate of melting pool geometry and grain growth simulation, which can provide a basis for decision-making on laser welding parameters. In the future, this H-beam steel laser welding technology will be applied to production line and extended to box column steel structures manufacturing development. It aims to transform the traditional high-energy consumption production methods in the steel structure industry and promote sustainable development with green architecture.
