Electron beam brazing temperature field PID control system;

Effect of processing parameters including brazing temperature and holding time on the joint mechanical property was also discussed by optical microscope,SEM and EDS.

The effects of brazing temperature and time on the structure and property of the brazed joint between graphite and TZM alloys with Ti-based filler in vacuum were presented.

The method to ensure proper soldering temperature and the principle for that is also dealt with.

The results showed that the IMC on the joint boundary indicated the difference in its formation and distribution under different soldering temperatures and times, resulting in the variation of the joint shearing strength.

The results show that the melting properties of the solder alloy are satisfactory,and the soldering temperature and time have much effect on the shearing-strength of the joints.

As shown from test,with improving of jointing temperature and prolong of heat preservation time,welding seal organize becomes asymmetry and becomes bulky and carrying capacity of welding seal is worst.
