焊縫外形 的英文怎麼說
中文拼音 [hànféngwàixíng]
焊縫外形
英文
bead contour-
Thus the fracture likely initiated from fatigue sharpened cracks originating from slag and void in the plug welds.
因此，斷裂可能是由於從塞焊焊縫內的焊渣和氣孔外形成的尖銳的疲勞裂紋而產生的。The calculation results indicate that the outboard of drum walls fall in plastic yielding at the same time the rising cooling water reaches the height of that point and the yield region becomes narrower and narrower when it comes closer to the circumferential strake weldments, which explains the reason coke drums experience bulging and cracks occur in the weld seams portions of shell to shell after long in service
計算結果表明：塔壁外側在冷卻水面到達的瞬間進入塑性屈服，筒節中部塑性屈服區較大，當靠近焊縫時塔壁的塑性變形區逐漸縮小直至消失，塔壁塑性屈服區的分佈特點解釋了塔體長期使用后發生鼓凸變形及簡體與焊縫連接處產生裂紋的原因。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。As plasma, welding arc has well electric character. exterior magnetic field can affect shape and movement of welding arc. and the welding bead and drops transfer can also be changed to improve the welding process and advanced the productivity
電弧作為一種等離子體，具有優良的導電性，用外部磁場可以改變電弧的形態和運動特性，影響焊縫熔池和熔滴過渡形式，大大改善焊接工藝，提高焊接生產效率。And the finite element method ( fem ) was used to simulate the stress and deformation of the outer casing and the bearing chock. on the basis of the experiments and fem analysis, the strength and fatigue lifetime, the interaction of creep and fatigue lifetime, the creep lifetime of outer casing and bearing chock have been analyzed, at the end of trail, sem analyses of failure section has been conducted
同時對航空發動機燃氣渦輪外機匣和軸承座進行了有限元模擬計算，得到外機匣和軸承座的焊接處的強度和變形情況的模擬結果。根據試驗數據和有限元的計算結果，對發動機燃燒室外機匣和軸承座兩種結構（包含焊縫）進行靜強度分析、疲勞壽命分析、蠕變壽命分析、蠕變疲勞交互作用壽命分析以及斷口的金相分析。In this paper, the general situation and virtue or disadvantage about light - steel structure abroad and at home is concluded systematically. the design method, steel characteristic in the connection, the bolt strength, welding line characteristic and the joint connection model about gabled frames structure is introduced
本文系統地歸納了國內外輕鋼結構的發展概況及其優缺點，介紹了輕鋼結構門式剛架節點的設計方法、節點鋼材的性質、螺栓的強度、焊縫的特性以及連接的形式。分享友人
