    高頻焊管金屬流線的形成形態(tài)與分析

    Analysis of Formation and Morphology of HF Weld Tube Metal Flow Line

    • 摘要: 焊管生產(chǎn)中主要工藝參數(shù)的合理選擇和匹配,是保證生產(chǎn)過程穩(wěn)定和產(chǎn)品質(zhì)量及提高生產(chǎn)率的關(guān)鍵因素。比較系統(tǒng)地介紹了高頻焊管金屬流線的形成、形貌 (集中表現(xiàn)為焊縫),對熔合線、熱影響區(qū)及金屬流線常見的各種缺陷和不良形態(tài)、產(chǎn)生的原因及其對焊管質(zhì)量的影響進行了闡述,并提出了金屬流線分析的操作方法。

       

      Abstract: Proper selection and setting of major technological parameters for HF weld tube manufacture is very criticalto ensure consistent operation and product quality and enhancement of productivity. All described here are details about the formation and morphology (mainly the seam) of the metal flow line of HF weld tube, and analysis concerning defects and bad morphology frequently identified in fusion line, heat-affecting area and metal flow line, and the causes therefor and negative influence on tube quality thereby. In addition, operation procedure for analysis of the metal flow line is introduced.
