焊缝

The property of the point of inner corner reflects the material single tensile property, the main function of the point is σ〓 and ε〓.

接管角焊缝内拐角点的特性基本体现了材料的单向拉伸特性，该点起主要作用的是σ〓和ε〓。

Through penetrate methods and observing microstructure,the type of corrosion is determined as intergranular corrosion.

通过材质鉴定、着色分析以及显微镜分析确定了该腐蚀的类型为晶间腐蚀，产生腐蚀的原因主要是焊接使焊缝附近的金属受热发生敏化现象以及材料本身存在的质量问题所致。

We should use the tempilstick to check the temperature for the preheating of the interlamination away from the soldering seam less than 75mm.

预热和层间温度都应用测温笔在离开焊缝不小于75mm 的地方进行检查。

The results showed that the fracture toughness of the weld of HFW pipe was lowest.The value of absorbed energy of HFW weld was closely related to the heat treatment process.But the fracture toughness of fusion zone of submerged-arc welded jointer,its microstructure was coarse granular bainite,and was lower than the other locations of heat affected zone;and with the increasing of steel strength,the effect of welding heat cycles on the pipeline steel became stronger,and form coarse microstructure in fusion zone leading to decrease fracture toughness.

结果表明，高钢级管线钢高频焊接焊缝处的断裂韧性最低，其冲击功大小与热处理工艺密切相关；而埋弧焊接热影响区断裂韧性在熔合线处最低，其主要原因是此处的组织为粗大的粒状贝氏体，而且强度越高焊接热循环对管线钢的作用越强，在熔合线附近更容易产生粗大组织，使断裂韧性降低。

Impurities of welding joints and metallic phase appearance of welding seam are analyzed and a comparison is made with the welding joist made with a magnesium crucible.

分析焊接接头夹杂物情况和焊缝金相组织形貌，并与使用镁质坩埚的情况进行对比。

A phototube mcunted under the back of the weld received a light from efflux plasma out of the key-hole and transferred it into a photoelectric pulse signal.

放置在焊缝背面的光电管接收并监控来自等离子弧尾焰的光线。接收到的光信号被光电管转换成光—电脉冲信号。

Painting 油漆 The necessary painting (touch-up painting) is partially done during the erection progress utilising the scaffolds mounted during the various erection phases, but NOTE: all field weld should be left unpainted up till completion of a successful Pneumatic Tightness Test.

安装阶段，利用安装工作中的脚手架，可以进行部分必要的油漆工作。但是注意：所有的现场焊缝均需等气密试验成功结束后方可进行涂漆工作。

It is shown that preventing welding hot cracking by mechanical methods can avoid the limitation of metallurgical methods and is very effective both for solidification cracking and for liquation cracking, thus has more freedom in choice of the parent metal and filler metal.

研究表明，采用力学方法防止焊接热裂纹可以避免冶金措施的局限性，对两类热裂纹（即焊缝凝固裂纹和近缝区液化裂纹）同样有效，因此，对焊丝成分和母材的选取有较大的自由度，是一种解决焊接热裂纹问题的重要的新途径。

In addition, effects of weld heat input on microstructure and performance of the weldjoints are analyzed. The test results indicate that by controlling weld heat input about 16kJ/cm and practicingmulti-layer weld process, the coarse austenitic grains in the weld metal and lumpish ferrite in the heat affectedzone can be avoided so that the microstructure and performance of the weld joints can be ensured.

结果表明，采用多道焊焊接工艺，严格控制焊接线能量在16 kJ/cm左右，可以防止T91钢焊缝区奥氏体晶粒粗大，避免在热影响区出现块状铁素体组织，从而保证焊接接头区具有良好的组织性能。

Macrograph of the fusion zone in the transverse section obtained from experiment and residual stresses determined by hole-drilling method are used to validate the simulated results. The experimental and numerical results are in sufficient overall agreement, which proves the validity of the finite element model.

实验得到的焊缝宏观形貌和小孔释放法检测到的焊接残余应力对计算结果进行验证，实验结果和计算结果吻合较好，证明了有限元模型的正确性。

The dynamic variation in content of cndogenous abscisic acid,indoleacetic acid,gibberellinsand isopentenyladenodines of normal juvenilefruit and dropped fruit was measured with enzyme linked immunosorbent assayin the course of physiological fruit drop of 'Shuizhang Longan.

应用酶联免疫法测定了水涨龙眼生理落果期间正常幼果和脱落幼果中内源激素ABA、IAA、GAs及iPAs含量的变化。
