虚焊

车身点焊接头虚焊缺陷的超声快速识别

Ultrasonic fast identification for faulty welded joint defects of auto-body spot welding

探讨了在组装过程中应注意的问题，以及针对内导体焊接易出现虚焊问题进行研究。

And some problems that should be noticed in the assembling process of RF cable assemblies , and the possible problem of inter conductor void-welding are also discussed .

该工艺是两种金属之间直接熔接，焊点美观牢固，没有锡焊引起的脆裂、氧化、虚焊、假焊。

The process is directly between the two types of metal welding , a solid solder joint appearance , there is no brittle fracture caused by tin solder , oxidation , solder false .

在晶体硅太阳电池薄片化发展及组件的生产过程中，存在许多缺陷问题，如碎片、断栅、黑片、花片、隐裂、虚焊、色差、脏污等。

While the development of thin slices of crystalline silicon solar cells with the module manufacturing process cause many defects , such as cracks , off-grid , non-uniform resistance , flower slice and so on .

随着科技的发展焊接丝网机械化水平越来越高，然而也随之出现了不少质量焊接问题，如经常出现虚焊、漏焊现象。

With the development of technology , the mechanization welding level of the screen is higher and higher , however there has been some welding problems appeared , such as false welding and lack of weld .

研究结果表明，采用这种方法不但可以定性评价虚焊接头与完好接头，还可以定量计算出上下表面压痕深度及熔核直径。

By using the method , not only the kiss bonding and the perfect joint could be evaluated qualitatively , but also the pressure mark depth of the upper-bottom surface and the spot weld diameter could be calculated quantitatively .

结果表明，钎焊温度从595℃提高到615℃时，熔蚀率从10%提高到25%，虚焊率从10%降低到2%；

The results show that with the increased brazing temperature from 595 ℃ to 615 ℃, the melting erosion rate increases from 10 % to 25 % , the false brazing rate decreases from 10 % to 2 % .
