焊缝

It lets you precisely direct the arc, establish the weld puddle faster and place the filler wire right where you want it, all of which prevents burn-through.

正好让你直接264焊缝屋里更快地树立了正确的填丝你想要的话，所有这一切使烧通过。

This work aimed to identify the effects of argon shielding on the impurity gas contents and toughness of submerged arc weld metals.

研究了在埋弧焊过程中采用氩气保护对焊缝氧、氮含量和冲击韧性的影响。

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。

gas shielded arc welding ; gas in weld metal ; CO_2; welding current ; mathematical model

有人曾对Ar -CO2 混合气体保护下焊缝金属中的气体含量与被焊金属和焊接参

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。

Cold lap is a condition where the weld filler metal does not properly fuse with the base metal or the previous weld pass material.

冷隔？由于熔敷金属没有很好的与母材熔合或没与前道焊缝熔合。

Meanwhile, as the growth of arc, the lost of arc heat quality becomes larger, so the heat quality which is used to fuse base metal and weld stick decreases, the weld width and weld reinforcement decreases comparatively.

同时，电弧增长后，电弧的热量损失加大，所以用来熔化母材和焊丝的热量减少，相对焊缝宽度和余高就略有减少。

Meanwhile, as the growth of arc, the lost of arc heat quality becomes larger, so the heat quality which is used to fuse base meta l and weld stick decreases, the weld width and weld reinforcement decreases comparatively.

同时，电弧增长后，电弧的热量损失加大，所以用来熔化母材和焊丝的热量减少，相对焊缝宽度和余高就略有减少。

The X-ray diffract was used to analyze the crystal structure of the composite. Results show that after the talc was treated with blend coupling agent, the crystal structure of talc changed, and effect Intercalation phenomenon.

通过X射线衍射分析可知，用混合偶联剂对滑石粉进行预处理后，滑石粉晶体结构发生改变，产生了插层现象，使PP／滑石粉复合材料为纳米复合材料。

An authentic Maui wedding might require the services of a 'kahu', which is a Hawaiian minister.

毛伊可能需要一个真实婚礼服务'kahu'，这是夏威夷部长。
