焊缝

The advantage of this is that thin material can be welded in the spray transfer mode which produces a smooth weld with less spatter than the short circuiting mode.

这样的好处是，可在喷射过渡方式下焊接薄材料，能产生比短路过渡飞溅少的平整焊缝。

When the weld metal deforms without substantial interaction with surrounding base material, an expression of a modification factor is presented, which can be used to calculate and analyze the effect of weld mechanical heterogeneity on the crack growth driving force.

在不考虑焊缝应变与母材应变相互干涉影响的前提下，本文给出了一个可以分析焊接接头各种力学性能不均匀对裂纹扩展驱动力影响的修正系数计算表达式。

After I weld in supports for the grates I will be right around that mark.

焊缝后，我在支持为栅，我会的权利，前后马克。

High-quality and high-performing welds, up to 2.5 inches thick, have been produced for 70% less than conventional joining costs and enable production of very wide wing panels from ISPs, which can be formed using bump forming, joggling, shot peening, and age forming Fig.

目前厚度达2.5英寸的高质量、高性能焊缝生产成本比传统焊接成本低70%。

The results show that the material mismatching has a great effect on residual stress distribution.

结果表明，焊缝强度对残余应力影响较大。

The limitation of traditional image processing method, which is usually too sensitive to noises, can be obviated with this algorithm. Hence, the accuracy of the detection for weld lines and computation for welding positions can be improved.

从哲学思想的角度提出了宏观处理与微观检测相结合的综合图像处理技术，避免了传统图像处理技术对噪声过分敏感的不足，提高了焊缝边缘检测和焊接位置计算的精度。

On the basis of that all frame offsets are given, a genetic algorithm is presented to optimize the object.

在建立全船肋骨型值的基础上，提出了改进的遗传算法来优化货舱区分段环焊缝位置方法。

The result shows that the equalmatching characteristic of 10Ni5CrMoV steel welded joint is prominent.The probability of equalmatching is 48.11%,as well as,that of undermatching and overmatching are 47.55% and 4.34%,respectively.The mean-value of strength matching coefficient is nearly higher than its lower ...

计算结果表明，10N i5CrMoV钢焊接接头的等强匹配特征明显，等强匹配概率为48.11%，低强失配和超强失配概率分别为47.55%和4.34%；强度匹配系数均值偏下限，为0.955；由于母材强度数据的标准差比焊缝要大，约为1.54倍，从而使得强度匹配系数离散度较大；此外，焊接接头强度匹配系数小于0.86的概率为2.96%，可能会导致焊接接头产生冷裂纹。

All pressure part welding on inner vessel not otherwise fully radiographed shall have root and cover passes subjected to magnetic particle inspection.

对于没有进行全面RT 的内层容器上所有受压件焊缝（不包括夹套，但包括盘管），第一层焊道和盖面焊道需要进行MT检测。

Self adiust functrion of electric arc igntion,less spatters,perfect weld appearance.

电弧自调节能力强，引弧成功率高，焊接飞溅小，溶敷率高，焊缝成形美观。
