Resistance welding and brazing possibly become the development trend.

电阻焊和钎焊有可能成为铝／铜焊接的发展方向。

Different combinations of nickel/titanium foils were used; brazing was done in vacuum at 6 x 10-6 torr at 960°C, 1010, and 1030°C for different brazing times.

不同组合的镍/钛箔使用；钎焊是在真空中在6× 10-6托在960 ℃， 1010年和1030年° C的不同钎次。

Silver brazing method: larger wire-bond or welding rod point in the valve in the pipeline sets seat.

银钎焊法：将焊线或焊杆点在阀门里的管道套座上。

Its are main the task is to produce welding flux kind product -- the recipe dissolvent that will come from French flounder and metal (lead - stannic alloy or stannum - silver-colored - copper alloy) mix and become, in order to passes drill rod solder will yuan parts of an apparatus is fixed in printed circuit board on.

其首要任务是出产焊剂类产物——将从法国辗转而来的配方溶剂和金属(铅-锡合金或者锡-银-铜合金)同化而成，用以经由过程钎焊将元器件固定在印刷电路板上。

In addition to the influences of brazing temperature and the composition of filler metal, the rate of solution of base metal into molten fil...

最后，在钎焊温度下对钎缝进行了不同时间的保温处理，发现钎缝的强度和抗弯能力仅有不大程度的改善。

The research indicate that the performance of brazing joint using Al-Ge-Si brazing filler metal precedes to the one using HL401 brazing filler metal. And the main reason is that brittle compound such as Cu2Al is not appeared in brazing joint.

本研究建立的2090Ce铝锂合金钎缝组织形态成长模型以及母材溶解厚度控制模型对钎料的选择、钎焊工艺参数的选择及接头钎焊间隙的确定等具有重要的参考和指导作用。

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。

It is suitable to be used as filling material for oxygen-acetylene gas welding and carbon arc welding, and also for manual braze welding. It is the ideal material for welding of copper alloy, copper, gray cast iron and hard alloy knife and etc.

HS221 JIS ZYCusN 适用于氧-乙炔气焊及碳弧焊时作为填充材料，也可用于钎焊，是铜合金、钢、灰铸铁及硬质合金刀具等焊接材料中较为理想的焊接材料。
