鋼結構一般被廣泛的用於大型結構,而電銲工程則為大型構件製造時之必備設施。本研究依據歷史資料探討分析目前電銲設備的使用、電銲災害的發生及其防範對策,包含電銲機、人員及操作的安全。特殊的防範措施包含感電防範、一次側及二次側防範設施、自動檢查及施工前之檢查等,其目的為教導施工人員正確的施工方法及確保電銲施工的安全,並減少電銲工程引起的災害。 Steel structure is commonly used in large-scale constructions project; while welding operation is essential when large-scale component are being manufactured. Based on historical records, this study investigates and analyzes the current usage of electric
