The results show that heating at1500oC for 10 minutes in vacuum is the best brazing process. In the ceramic side none defects was observed at the interface of ceramic and solder, which leads to uniform brazing seam and excellent airtightness.

本文对单晶Al2O3/Pd/Nb焊接工艺、界面组织结构等进行了研究分析，结果表明在真空状态下，温度为1500℃，保温10分钟得到的焊缝均匀一致，没有任何的孔洞缺陷，气密性检测说明焊接情况良好。

50Mm ;Tack welding and the welding for tools and clamps shall be performed by qualified welders; and the welding procedure shall be the same as that of formal welding.

定位焊及工卡具的焊接，应由合格焊工担任，焊接工艺应与正式焊接相同，引弧和熄弧，应在坡口内或焊道上进行。

Of a dish and a dish use the work word steel the welding pays to accept, a dish inner part adoption the Cape iron and the slot steel welding become whole framework, because of conveyance space limit, each dish is divided into two part, combination hour in the interval adoption M18 fix the stud bolt connects with each other to counteract the electric welding 焊 dead, the shape bottom use 8100 mms work word steel welding be used as to pay to accept, and with before install work well of the cement pillar foundation sprinkle to cast into the integral whole.

圆盘与圆盘之间用工字钢焊接支承，圆盘内部采用角铁与槽钢焊接成整体骨架，由于运输空间限制，每一圆盘分为两部分，组合时其间采用M18固定螺栓相连并用电焊焊死，造型底部用8根100mm工字钢焊接做为支承，并与安装前做好的水泥柱基础浇铸成一体。

Wires can be welded to difficult bases by first passing them through a short stub tube of similarmaterial, and then welding the assembly to the base.

或者，一开始将焊接线穿过一个与基体材料材质类似的短管，然后把组件焊接到基体上，通过这种方法可把任何的材料焊接在基体上。

The welding distortions of the main beam and side beam of expansion and contraction beam are predicted and analysed based on the welding distortion calculation method of relative shrinkage volume.

采用基于相对收缩体积的焊接变形理论计算方法，对伸缩缝梁的中梁和边梁结构的焊接变形分别进行了预测、分析，并对实梁的焊接变形量进行了测试。

is first been used to describe the gap and root face of welding seam which is the important feature sizes and the welding current which is the most important controlling parameters MIG welding penetration and the welding time in quantity and the fuzzy math.

依据这一特征，应用模糊数学的方法对焊缝的重要特征尺寸间隙和纯边、MIG焊熔透的重要控制参量焊接电流以及焊接时间给予定量描述，并建立了视觉弧焊机器人焊接参数自动规划模糊数学模型。

Welding materials used bolt nail on the effects of welding and engineering quality have great impact on Beijing Weidi produced by the welding bolt nail in this area has a high level of skills and rich experience in practice, manufacturing of high-quality screw bolt.

焊接用栓钉的材质对焊接效果和工程质量有很大的影响；北京威迪公司生产的焊接用栓钉在该领域有很高的技术水平和丰富的实践经验，生产制造着高质量的栓钉。

Simulation of robot welding process is completed with the application of ROBOGUIDE, the simulating path is changed to TP program for practical welding, and TP program is transferred to robot controller, which all the work about off-line programming and simulation of the saddle-backed welding seam are completed.

应用离线仿真软件ROBOGUIDE完成马鞍型焊缝曲线焊接过程的仿真，将仿真路径转换成实际TP程序，并输入到机器人控制柜，完成马鞍型焊缝焊接过程的离线编程及仿真，运行TP程序完成马鞍型焊缝的实际焊接。

The result shows that, when a free droplet transfer mode is applied in high-speed welding , the workpiece is heated by the arc throughout the process and thus the molten pool can not solidify in time.As a result, the molten pool is very long, which gives way to the instability of bead formareron and pinch effect of the liquid metal,so that it finally leads to the humping phenomenon. Based on the analysis and experimental result, the short-circuiting transfer mode is suggested to improve the bead formation in high-speed welding .

理论分析和试验结果均表明，采用自由过渡的熔滴过渡形式进行焊接，工件始终处于焊接电弧的加热下，在高速焊接时，熔池不能及时冷却，熔池明显拉长，由扰动引起的振动波长大，当熔池的拉长达到一定程度时，会发生液体金属的失稳和颈缩的现象，造成驼峰焊道。

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。
