电弧

Now in A-TIG welding, the coefficient of arc shrinking and the weld pool surface tension result in penetration increased.

目前认为A- TIG 焊使熔深增加的机理是电弧收缩和表面张力共同作用的结果。

Therefore, non-contact temperature measurement technique becomes the development trend of high temperature measurement and will be used more and more widely in measuring the temperature field of weld arc and pool.

非接触测温主要有辐射法和干涉法，由于测温元件不与被测物接触，不会破坏被测物的温度场，通过与数字图象处理技术相结合，能实现温度场的快速、实时测量，全面、形象的反映温度场的动态变化，因此成为高温测量技术的发展趋势，在焊接熔池和电弧温度场测量中得到越来越多的应用。

After the analysis of weld electric arc message, the variation laws of keyhole effect in plasma arc welding have been understood.

本文对等离子弧的电压信号和声音信号进行了深入地研究，首次使用电弧电压信号和声音信号定量地识别了&小孔效应&的变化。

Use alternating transverse magnetic-field to control dragged arc , overcome weld undercut, and improve the appearance of weld.

所以控制电弧后拖是高速焊改善焊缝成形的关键。

Use alternating transverse magnetic-field to control dragged arc, overcome weld undercut, and improve the appearance of weld.

本试验采用交变横向磁场来控制电弧的后拖现象，克服咬边，改善成形。

It found that the course of practice outside in the optical electrode coated layer formed by a variety of minerals such as medicine skin can burn arc stability, weld quality is improved, this electrode is called drug skin electrodes.

人们在实践过程中发现如果在光焊条外面涂一层由各种矿物等组成的药皮，能使电弧燃烧稳定，焊缝质量得到提高，这种焊条叫药皮焊条。

In addition, more than 20 kW of high-power lasers for welding of more than 10 mm thick steel plate, as a result of higher heat input, low cooling rate, the degree of hardening of the weld with manual arc welding and gas close to Paul.

另外，使用超过 20 kW的大功率激光器来焊接10 mm 以上的厚钢板，由于输入热量更高，冷却速度变低，焊缝的硬化程度将与手工电弧焊和气保焊水平接近。

The weld arc property characteristic, weld microstructures and mechanical properties are researched systematically, by carrying out welding technology tests for many typical welding materials.

采用多种典型焊接材料，系统进行了外加纵向磁场对GTAW焊接电弧特性、焊缝组织和接头性能的试验研究。

Subject: welder testing The ARC and TIG machines appear to be dual purpose so they should be OK 1.however, the photo's only showed one MIG machine and I would like to know how many MIG's they have.

主题：焊工测试电弧和TIG机器似乎是双重目的，所以他们应该会没事依照片上的，只不过是一个米格机，我想知道有多少架米格的，他们有。

Poor contact with the pliers will allow arcing at the jaws, which will damage the pliers and the wire, and rob energy from the intended weld.

与钳子接触不好会在钳子口处产生电弧，这样会损坏钳子和热电偶线，同时还会损耗焊接机的存储电能。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
