鋼構雷銲發展趨勢

在全球減碳與永續發展壓力下，鋼構產業正面臨傳統銲接工法高能耗、高人力需求及品質不穩定等挑戰。雷射銲接技術憑藉能量集中、熱影響區小、自動化程度高等優勢，可大幅降低填料與能耗，提升生產效率與結構品質，成為鋼構製造升級的關鍵方案。工研院與產業界已成功開發H 型鋼構與箱型柱型鋼構雷銲工法，並建置自動化試產線，驗證其全滲透、高精度及低碳排的製程效益。研究結果顯示，新工法可減少填料90%、能源消耗與碳排逾70%，未來此技術可延伸至風電、石化與大型鋼構工程，推動鋼構產業邁向智慧化、低碳化與國際化發展。

Under the global pressure of carbon reduction and sustainable development, the steel structure industry is facing challenges from traditional welding processes characterized by high energy consumption, intensive labor requirements, and unstable quality. Laser welding technology, with advantages such as high energy concentration, small heat-affected zones, and a high degree of automation, can significantly reduce filler usage and energy consumption while enhancing production efficiency and structural quality, making it a key solution for upgrading steel structure manufacturing. The Industrial Technology Research Institute (ITRI), in collaboration with industry partners, has successfully developed laser welding processes for H-beam and box-column structures, and established automated pilot production lines to validate the benefits of full penetration, high precision, and low carbon emissions. Results show that the new method reduces filler usage by up to 90% and decreases energy consumption and carbon emissions by more than 70%. Looking ahead, this technology can be extended to offshore wind, petrochemical, and large-scale steel structure projects, driving the industry toward intelligent, low-carbon, and globalized development.
