General dimensional tolerance and geometric tolerance stipulated in this standard are applicable to weldment, welding assembly parts, and welded construction.

本标准规定的一般尺寸公差和形位公差适用于焊件、焊接组装件和焊接结构。

The ladder-shaped public connection of thrash pipe union is welded with exit port of wessel or paste pot,or the ladder-shaped public connection is weldde with steel tube port with relevant diameter.

安装1、锤击由壬的梯形公接头与容器或泥浆出口孔相焊接，或将梯形公接头焊接于相应直径的钢管端口上。

Taking the important equipment on an automobile wilding line,wilding jig as example,the work piece similarity model is presented based on work piece type,geometric and location information,and then a case database about wilding jig design is established.

以汽车焊接生产线上的关键工艺设备焊接夹具为例，提出以工件类型、几何及定位信息为基础的相似性评价模型，在此基础上建立了夹具设计事例库。

In order to produce wind tower body and turbine support appliances, HuaWei Special Steel Strip Company is planning to build up Material-Storage workshop----cutting equipments---reeling equipments----riveted-welding workshop and Metal-processing workshop which will along with some equipment such as heat treatment stove, shot blasting and firing painting Room and so on.

Some welding parameters attribute values,such as current,voltage etc,were acquisited in GMAW process.

检测了熔化极气体保护焊中焊接电流和电弧电压大小等参数特征，利用数字信号分析与处理中的时域自相关特性原理，分析GMAW熔滴过渡过程的稳定性与参数关系，判断焊接电流和电压是否具有周期性。

It was found that the mechanical properties of the joints decreased by the alclad and it will be increased dramatically by removing the alclad. The effect of alclad on the bottom surface is larger than on the top surface. The mechanical properties of 2024-T3 joints will fall down because alclad is entrapped into the welded joints by the rotating and stirring tools during the friction stir welding, similar with "inclusion" in fusion welding.

研究结果表明，包铝层的存在明显降低了2024-T3铝合金搅拌摩擦焊接头的力学性能；去掉包铝层后接头的性能显著提高；下表面包铝层对接头性能的影响大于上表面包铝层；当2024-T3铝合金表面带有包铝层进行搅拌摩擦焊接时，在搅拌头的旋转和搅拌作用下，包铝层被卷入焊缝中，形成类似于熔焊的&夹杂&，从而使得接头的力学性能下降。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
