焊缝

In order to insure performance of intercrystalline corrosion resistant and hot cracking resistant, structure of surface layer of weld metal should be austenite and 4%～12% of ferrite.

为保证复层焊缝良好的耐腐蚀和抗裂性能，采用25-13型铬镍奥氏体焊条堆焊，复层的组织应为奥氏体和（4％～12%）的δ铁素体。

In the same condition of inner wall thickness, materials and working pressure, the emphasis is to make comparative analysis about ribbon and jacketed structure, forms of welds, distribution and kinds of stiffeners.

在内壁厚度、材料和工作压力等相同的情况下，重点对绕带式和夹套式结构、焊缝形式、加强筋的布局和种类等做对比分析。

Metallograph and SEM observation of the tensile fracture show that the crystal grain of the WTIR weld is finer and the metallurgical structure is more compact than that of the ordinary weld.

金相和拉伸断口 SEM观察表明，随焊冲击碾压焊缝区晶粒明显细化，组织更加致密，气孔、缩松等缺陷大大减少。

Cold Weld. A metallurgically inexact term generally indicating a lack of adequate weld bonding strength of the abutting edges, due to insufficient heat and/or pressure.

冷焊缝。通常由于焊接温度或挤压力不够，使焊接的两对边结合强度不足。

The comprehensive effect of partial acidlity of working medium, flowing status of fluid, nocuous material in atmosphere, together with the overlong usage, largely increased the corrosion rate and caused the leakage.

结果表明，泄漏的主要原因是焊接缺陷导致焊缝区发生缝隙腐蚀，而工作介质的局部酸性、流体的流动形态、大气中有害物质、温差应力等综合作用，加上使用期过长等加剧了腐蚀，导致该塔泄漏。

Current pulses of controlled rise rate ,producted with advanced electronic techniques , improve the quality of the weld.

利用先进的电子技术控制电流脉冲的上升速度，可以提高焊缝的质量，这种焊接技术用手工和自动的方法都可以实现。

Retortable stand-up pouch, for example, for fresh pet food: easy tear opening; FDA approval; high seam seal strength

压热杀菌直立袋，用于装新鲜宠物食品：易撕开；FDA认证；高焊缝强度

We'll have the roentgenoscopic selective examination of the 10% welded seams.

我们将对其中10%的焊缝进行X 线检查。

The dependability about the welded seaming tracking system of three-dimensional vision based on the structure light is tested through experiments.

并通过试验验证了基于结构光三维视觉传感器焊缝跟踪系统的可靠性。

Through the microstructure analysis, it is found that there are ferrite, spiculate bainite in base material, weld metal area and heat-affected zone, and there is much dispersed Fe3C on ferrite and bainite, which indicates that weld joints of steel B610CF have better strength and toughness.

金相分析表明，焊接接头的母材区、焊缝区和热影响区组织均为铁素体和下贝氏体，在铁素体和贝氏体上还弥散分布着渗碳体，说明焊接接头的强度和韧性都较好。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
