焊缝

Though the gyration and retroflexion of the workbench, the welding positioner can make the welding line to an ideal position, which can improve the quality of the welded joint, reduce welder's workload. It is ideal equipment especially fit to weld the kinds of workpiece, just like the shaft, tray, canister, and so on.

焊接变位机可水平翻转角度，通过工作台的回转及翻转运动使工件上焊缝处于最理想的位置进行焊接，从而大大提高焊缝质量，减轻焊工劳动强度，尤其是适合焊接各种轴类、盘类、筒体等回转工件的理想设备。

The brazing seam mass is therefore good and bad the mass being related to a weldment is good and bad , mass that can affect to weldment sigmatism function , how to raise therefore, we answer a brazing seam carries out the analysis studying.

因此焊缝的质量好坏关系到焊件的质量好坏、会影响到焊件的使用性能，所以，我们应对如何提高焊缝的质量进行研究分析。

Connecting of doubler strake is a relatively weak link, fatigue strength of which is largely reduced due to the influence of the weld flaw, weld inside stress and weld surface figure. If the ship is under the alternate load function for a long time in long service, fatigue destruction of connecting may happen, strength of deck plating or bottom plating strengthened may also be influenced.

复板条的对接接头是一个相对薄弱的环节，由于焊缝缺陷、焊接内应力、焊缝表面形状等因素的影响，使得接头的疲劳强度大幅度降低，船舶在营运过程中长期受到交变载荷的作用，就会引起对接接头的疲劳破坏，继而影响到被加强的甲板或船底板。

The results showed that the enhanced stirring action of the liquid metals in weld pool due to peak-current fluctuating periodically under single-wire synergic pulsed MIG welding decreased temperature gradients and increased heterogeneous nuclei within the region of constitutional supercool...

试验结果表明，单丝复合脉冲焊接时，峰值电流周期性变化引起的熔池液体强烈的搅拌作用，使熔池的温度梯度降低，固液界面前沿成分过冷区中的形核核心增加，促进了焊缝组织的细化，提高了焊缝的强度和塑性。

In this paper, the characteristics of ultra fine grained steel s are firstly introduced Then its weldability is discussed,including properties and cracking susceptivity of HAZ and weld meta

介绍了超细晶粒钢的特点，针对这些特点，讨论了超细晶粒钢的焊接性，其中包括HAZ性能、焊缝性能、HAZ和焊缝的裂纹倾向等。

This paper proposes a detection method based on support vector machine based on analysis and comparison with several other methods.

该文在分析和比较几种焊缝缺陷识别模式的基础上，提出了基于支持向量机的X射线底片焊缝缺陷识别方法。

There are many ways to make a weld and many different kinds of welds.

焊缝制备的方法有很多，也有很多种不同类型的焊缝。

The results show that the addition of Zr increases the content of acicular ferrite and improves the microstructure of weld metal.

结果表明，锆的加入增加了焊缝金属中针状铁素体的含量，改善了焊缝金属的微观组织。

The composition and cooling rate of the weld metal are the main influencing factors on acicular ferrite.

结果表明，焊缝金属化学成分和冷却速度是影响针状铁素体的主要因素，应力对焊缝金属相变的影响很小。

A commonly observed welding defect characteristically occurs at high-speed welding, such as humping weld. Humping is the periodic occurrence of beadlike protuberances.

但焊接速度提高的同时也更容易产生焊接缺陷，如驼峰焊道，即焊缝金属沿焊接方向上分布严重不均的焊缝成形缺陷。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
