焊料杯口和管道之间的间隙应该大致在0.0254毫米至0.254毫米之间，才能够获得正确的铜焊连接效果。

To make a proper brazing joint, the clearance between the solder cup and the tube should be approximately 0.001" to 0.010" (0.0254mm to 0.254mm).

h额定内部压力是所连接的管道额定内部压力。如果可以采用焊料，则推荐使用铜焊合金。

Rated internal pressure is that of the tube being joined. While solders can be used, brazing alloys are recommended.

这些合金用于定位焊接和铜焊的焊料，和用做打磨或模铸。

These alloys are used for welding and brazing filler materials and for sand and die castings.
