中文拼音 [hànfénglièwén]
焊縫裂紋
英文
bead crack-

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。All cracks were detected in regions where such manually made weld passes existed.
所以檢查到的裂紋都位於有手工焊縫存在的區域。Often lack of fusion adjacent to the girder web in the transverse groove welds led to the cracking.
在靠近主梁腹板的橫向坡口焊縫處常常出現未熔透而導致裂紋。Method of t - joint weld cracking test
T型接頭焊縫裂紋試驗方法The second crack is a crack originating at the groove weld toe of the column flange-girder flange connection.
第二種是產生於立柱翼緣與主梁翼緣連接處的坡口焊縫焊趾處的裂紋。Cracks that have developed in the web at lateral connection plates have generally occurred because of intersecting welds.
腹板在水平連接板處出現裂紋,通常是由於有交叉焊縫。Minimal the tendency of microcracks can be obtained by improving the shape of weld pool and enhancing the welding energy input
通過改善焊縫成形和提高焊接線能量有助於減小兩類熱影響區微裂紋傾向。Abstract : in view of the quantity examination of weld defect by ultrasonic, on the basis of theoretical analysis and test, the cause, composition and contriling method of error of crack defect size h have been analyzed systematically, a controlling and statistical method of ultrasolic examination error has been put forward. this method is simple and suitable, and has been verified by test

本文將基於裂紋閉合現象建立的帶狀屈服模型,用在平面貫穿裂紋中,計算此時的裂紋張開應力和疲勞裂紋擴展壽命,與試驗結果和經驗公式比較,驗證newman裂紋張開應力理論在高強鋼中的可行性;然後,用切片合成法,把潛艇結構凸錐柱結合殼焊縫處的三維表面裂紋分解成平面貫穿裂紋,用帶狀屈服模型的理論來分析平面貫穿裂紋,得到裂紋沿深度方向的擴展速率,進而得到潛艇結構的疲勞壽命。Brushed stripe coating to all areas such as corners. edges, welds. small brackets, bolts, nuts. rivet - s. and interstices, before spraying application of each coat, to ensure that these areas have at least the minimum specified film thickness
在塗抹新塗層前,應刷掉所有區域的麻紋,比如各角落、邊緣、焊接處、小托架、螺釘、螺帽、鉚釘和裂縫,保證這些區域至少達到價格的最低膜厚度。The welding line microstructure of ticp / fe in situ composites gained by different welding technologies and welding methods was different. however the microstructure was diffused on the welding line and there were no welding defects, the welding quality was better. the tic reinforced particles on the welding line still kept the same shape as that of the casting microstructure
原位tic _ p fe復合材料採用不同焊接工藝和焊接方法所得的焊縫組織有所差別,但焊縫處的組織均勻,沒有裂紋等焊接缺陷產生,可焊性較好;焊縫處的tic增強顆粒仍保持鑄態組織中tic增強顆粒的形態。Any severe deficiency of welding seams surface like cracks, pores, slags is forbidden
焊縫表面不得有裂紋,氣孔,夾渣等嚴重缺陷With the experiment of surface crack growth of bhw - 35 weld metal, the law of the surface crack shape variation when it grows was obtained, and the law of surface crack growth rate was also gotten. these direct the evaluation of the surface crack fatigue growth life and the critical value of its length
