焊缝金属

The results show that the flow is not symmetric about the weld centerline.

结果表明，塑性金属流动关于焊缝中心并不对称。

A new technology is put forward which uses weld with trailing impactive rolling to control the welding stress and distortion of thin component and to prevent welding hot cracking.

提出了随焊冲击碾压控制薄壁构件焊接应力变形、防止焊接热裂纹的新方法，其原理为：通过前后冲击碾压轮，分别对焊后尚处于高温状态的焊趾和焊缝区金属施加一定频率的冲击碾压力

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。

An extremely hot flame can be produced from an oxyacetylene torch. For certain welds an electric arc is used.

氧乙炔焊炬可能会产生极其热的火焰，对于某些焊缝来说可能会用到电弧，在此方法中，电流通过两个电极，并且金属表面被置于两电极之间。

So that the aim of reducing spatter and improve formation of weld is realized.

以实现减小金属飞溅和改善焊缝成形。

In general no porosity is observed in the seam when the length of claviform intermetallic compound is less than 10 μm. Moreover, the microstructure in the seam plays a key role in the diameter of the pore.

界面棒状的金属间化合物长度低于10 μm时一般不产生气孔，而气孔的直径与焊缝内部的微观组织有关。

Cold lap is a condition where the weld filler metal does not properly fuse with the base metal or the previous weld pass material.

冷隔？由于熔敷金属没有很好的与母材熔合或没与前道焊缝熔合。

To get a property comparison of GXHJ－ 1 sintered welding agent with SJ101 sintered welding agent, related tests were carried out, including deposited metal test, lab butt－ joint plate test, single－ welding stick operation test, double－ welding stick operation test as well as operation test with H08C welding stick, focusing differences of the two in terms of technological properties and weld seam impact toughness.

为了比较 GXHJ－ 1和 SJ101两种烧结焊剂的性能，分别从熔敷金属性能试验、实验室对接板试验、单丝焊生产、双丝焊生产等方面及在匹配 H08C焊丝的条件下进行了工艺性能和焊缝冲击韧性对比。

The weldability, deposited metals mechanical properties and purity of the new developed shell butt welding SAW material as the same level compared with Kobe Steel US-521HD/PF-500D.

研制的容器主焊缝埋弧焊材与国外典型的埋弧焊焊材在焊接工艺性能和熔敷金属力学性能及纯净度方面对比，结果表明研制焊材与日本神户制钢所的US-521HD／PF-500D焊材相当。

When the microstructures of weld metal and coarse-grained HAZ mainly consist of lower bainite the toughness is the highest.

当焊缝和热影响区金属主要由下贝氏体组成时，冲击功最高。

With the development of highway construction, the speed of cars has been gradually increased.

随着公路的发展，汽车的车速也在不断提高。

So we basically had to develop a bond with the animal in terms of socializing with it.

所以我们就主要想通过跟它沟通的方式来建立一种良好的关系。
