焊接

Devices should be soldered to boards rather than socketed, and of course, minimal air flow over the surface can greatly help reduce the package temperature.

焊接设备应以议会而不是嵌，当然，在表面最小空气流量可大大降低包装温度。

Ionized helium at least, the density minimum, it can quickly disperse from the metal bath of metal vapor produced by an increase, so to use helium as shielding gas, the plasma will be to maximize the suppression, thus increasing the penetration depth, improve welding speed.

氦气电离最少，密度最小，它能很快地驱散从金属熔池产生的上升的金属蒸气，所以用氦作保护气体，等离子体将被最大程度地抑制，从而增加熔深，提高焊接速度。

To cater for the various wire is particularly applicable to X42-X70 grade pipeline steel monofilament fast and multi-wire welding.

配合各种焊丝特别适用于X42-X70级管线钢的快速单丝及多丝焊接。

The control circuit made up of double monostable circuit IC has realized some remarkable functions, such as cycle control , zero crossing trigger, and preventing from repeated and error trigger.

所设计的控制电路，利用双单稳电路 IC，实现了点焊过程周波控制、过零触发，以及防重触发和误触发功能，保证了焊接过程稳定、可靠。

Connecting rod bearing φ25 methods, there are three commonly used: connection, mortise and post-I welding.

25支承杆的连接方法，常用的有三种：丝扣连接、榫接和剖口焊接。

The principle that weld pool size is well correlated with the frequency of natural oscillation excited on weld pool surface has been used for a real-time full-penetration control in the TIG welding of steel.

焊接熔池自然振荡频率与熔池尺寸之间存在良好对应关系的原理。

Familiar with petrochemical,chemical and fertilizer engineering or the knowledge of chemical equipment,welding or NDE.

熟悉石化、化学、化肥等工程或化工设备、焊接、探伤等方面知识

The welded joints in the analyses were generally accepted as failure –free and the joint transiton regions included in the calculations are negligibly small.

被焊接的关节在那通常分析自由地被认为是失败–而且被包含在计算之中的联合 transiton 区域是 negligibly 小的。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
