The dcep mig has the characteristic of deeper penetration which can reduce defective fusion and good arc stabilization. the dcen mig has the characteristic of shallow penetration of welding seam, and the welding wire has a high melting speed. so the variable polarity pulsed mig is a new technology for the welding of aluminium alloy sheet
變極性脈沖mig焊是一種新的焊接工藝方法，其綜合了dcep脈沖mig焊熔深較大、可以減少焊縫的熔合不良、電弧穩定性好和dcenmig焊焊縫熔深淺、焊絲熔化速度較快的特點，減小了焊縫的熔深，增加了焊絲的熔化速度，是一種適合於薄板鋁合金焊接的新方法。 -
Combined with the research project of the advanced performance of wire rope in the port cranes, a key technological problem of the ministry of communications, this dissertation investigated the stress - effect on the magnetic flux leakage ( mfl ) of wire ropes and the law of the mfl signal changes during wire rope fatigue testing by experiments and modern signal processing methods based on the ferromagnetic theory, being aimed at the present problems of current wire rope testing technology. the characteristic parameters and quantitative descriptive specifications for wire rope defective signal were analyzed in detail. this dissertation present a novel method of quantitatively evaluating locate faults ( lf )
本文結合交通部重點科技項目「港口起重機鋼絲繩傳動件的高性能技術研究」 ，針對當前鋼絲繩電磁檢測技術中所存在的問題，以鐵磁學為理論基礎，以試驗和現代數字信號處理技術為手段，對鋼絲繩漏磁信號的應力效應、鋼絲繩疲勞損傷歷程中的漏磁信號變化規律做了深入的研究，對鋼絲繩缺陷信號的特徵參數和缺陷的定量描述指標做了詳細的分析，提出了一種局部缺陷的定量逼近方法。
