焊缝

M: c6 b8 m* g; l% V Cleaning the tool doesn't just prevent weld contamination, it also keeps the shop from smoky grease fouling the shop air.

清洁工具不只是防止污染焊缝，黑烟也不断从店内店外空油脂污垢。

At present, brazing technology are widely adopted at home and abroad . In order to verify the availability and applicability of pulse Nd:YAG laser-welding, a comparison is made between the new technology and the present technology in such aspects as the dismantled torsions, the microstructure and the micro-hardness of the weld area and the heat-affected zone, the maintenance of fabrication precision and assembling precision of the components.

本文首次采用灯泵Nd：YAG脉冲激光进行焊接试验，并和硬钎焊获得的拆卸扭矩、焊缝金相组织、显微硬度等进行了综合对比，结果表明，激光焊接能很好地保证支架和支架轴固有的机械性能、耐磨性、加工与装配精度；激光焊连接可靠，耐拆卸扭矩大，符合整体结构性能要求；焊后无需后续处理，可以作为最终工序，验证了激光焊接的有效性、适用性。

No spalled paint exists at the plug weld and for a short distance each side of the plug welds.

在塞焊焊缝处及塞焊周围距离内无细漆碎屑存在。

The welds need to be sanded down more and smugged with a hot metal tool.

焊缝需要用砂纸更和smugged与铁水的工具。

The blue circle oxide films on fuel rods near the welded zone by electron beam welding were formed after corrosion tests.

燃料棒电子束焊接试样腐蚀后，在近环焊缝区会出现蓝色氧化膜环现象。

These products are the highly effective polishing and grinding tools for 号derusting, paint-removing, deburring, and welds-grinding of metal and non-metal material, and are broadly used in shipping, aviation, automobile, petroleum, and construction installation.

广泛使用于船舶、航空、汽车、石油、建筑安装等行业。是目前金属与非金属材料大面积除锈、除漆、除毛刺、磨焊缝的高效抛磨工具。

The influence of strength and thermal expansion coefficient mis-matching between the weld metal and the parent metal on the distribution of welding residual stresses was simulated by using the method of thermal elasto-plastic finite element analysis in this paper.

摘要］ 采用有限元法对相同温度场的焊缝与母材强度和线膨胀系数匹配影响焊接残余应力的规律进行了数值模拟。

Thus. for the parent metal of the higher yield strength σ〓, it is benifit for reducing residual stress with selecting strength overmatched joint.

表明屈服强度较高的母材选用适当高强匹配的焊缝对于降低焊接残余应力是有利的。

Where filler materials having tensile properties deviating from the parent metal are used, this fact must be taken into account when dimensioning the weld joints.

从母材部分开始使用具有伸缩性的填角材料之处，计算焊缝时应该考虑到这种情况。

It seems likely that Kraft will return with a better offer.

看起来卡夫要重新考虑一个更好的出价了。

But he'd rather burn off my feelers and watch me squirm.

可他却放任那个家伙对我为所欲为！
