焊縫外觀
英文
bead appearance-
In addition to, the fatigue crack between web and upper flange of welded steel crane beam on heavy duty service was discussed, and based on long - term observation and research, the author classified fatigue crack into bearing type and middle type crack along the horizontal direction. the causation, distributive law and mechanism of the crack were analyzed, and the precautions to take and the measures to remedy crack were presented. the main defacts including damage, crack, erosion and aging in structures, especially in concrete structure were introduced ; the defact mechanism was analyzed and the precautions to take were also given
另外，作者對重級工作制焊接鋼吊車梁腹板與上翼緣連接焊縫的縱向水平疲勞裂縫進行了長期的觀察和研究，根據疲勞裂縫產生的不同機理，將其分為支點裂縫和肋間裂縫，並討論了兩類裂縫產生的原因、分佈規律、機理以及防治的措施；對工程中經常遇到的結構構件，尤其混凝土構件的幾種主要病害（損傷、裂縫、腐蝕與老化）進行了機理分析並提出了防治措施。And it investigates the appearance condition ( including joint, crack, eroding, corrosion, braking pole device rupture, crane - girder ' s gnawing railway and so on ) of the whole crane - girder system on the spot, at the same time, it also actually examines the stress of the beam, chemical ingredient, distortion and railway excursion, etc. through sampling, and based on the actually examined results, it checks and calculates the carrying capacity of crane - girder system. then, based on the investigating on the spot and the calculated result, it discusses the mechanism of fatigue failure of the upper part of welded steel crane - girder, analyses the reason of steel crane - girder in the high - frequency emerging the fatigue crack, institutes the strengthened method of damaged steel crane - girder of accurate packing up workshop of the primary mill plant. finally, it presents some advice and suggestions for the repairing and strengthening method of fatigue crack of upper part of steel crane - girder in the high - frequency
針對包鋼初軋廠精整車間鋼吊車樑上部區域出現裂縫這一問題，本文首先綜述了國內外關于焊接鋼吊車樑上部區域疲勞裂縫的研究現狀；其次對整個吊車梁系統的外觀情況（包括連接、裂縫、腐蝕、銹蝕、制動桿件斷裂、吊車啃軌等）進行了現場調查，抽樣實測了梁的應力、化學成分、變形及軌道偏移等，根據實測結果，對吊車梁系統的承載能力進行了驗算；然後，根據現場調查及計算結果，探討了焊接鋼吊車樑上部區域疲勞破壞的機理，分析了重級工作制鋼吊車梁出現疲勞裂縫的原因，制定了初軋廠精整車間破損鋼吊車梁的加固方案；最後就重級工作制鋼吊車樑上部區域出現疲勞裂縫的修復與加固方案提出了一些意見和建議。Sonic new ideas and views were proposed, such as regulation on general welding procedure qualification and its method of application, welding procedure qualification between heat exchange tube and tube sheet assessmented by the thickness of fillet weld, and so on
本文還首次提出一些新思路、新觀點，如母材、焊材分類細則以及標準以外材料分類要有分類報告佐證；通用的焊接工藝評定規定及使用方法；換熱管與管板的焊接工藝評定是評定角焊縫厚度；氣瓶焊接工藝評定是兩個類型評定的結合，也可以分別評定。Weld positioning under load without installation, seam thickness of the seam thickness of not less than two - thirds of the design, not to exceed 8 mm, should not be less than 25 mm in length weld, located in welds inside
安裝定位焊縫不需承受荷載時，焊縫厚度不少於設計焊縫厚度的2 / 3 ，且不大於8 ? ，焊縫長度不宜小於25 ? ，位置應在焊道內.安裝焊縫全數外觀檢查，主要的焊縫應按設計要求用超聲波探傷檢查內在質量.上述檢查均需做出記錄Before apply the test, all the welding work of block or section should be finish and accepted by view inspection
當片體、分段組立裝配焊接完工後，經焊縫外觀檢查合格后，就可進行角焊縫密性試驗。Visual examination of weld
