Compared with prior art, it is an advantage of the current invention that: the reaction chamber inwall of the present invention uses ring-type level groove, because of ring
Welding slag slower for mobility can be adsorbed on ring-type level groove by shape platform level groove, can be retained in reaction by welding slag after reaction
Intracavity, is avoided that welding slag enters in weldment with the copper liquid of fusing, is not only effectively improved the welding quality of weldment；And
Product surface after welding is the most smooth, and secondly, the reaction chamber of the present invention uses upper and lower two reaction chambers, occurs at upper reaction chamber
During pyroreaction, copper liquid melted in upper reaction chamber can quickly enter in lower reaction chamber, both avoided because of moment reaction copper liquid from
Upper reaction chamber overflows, and accelerates the flow velocity of copper liquid, the most effectively extend the time of copper liquid and weldment frit reaction, make
Welding quality is more preferable, flows into rapidly lower reaction chamber due to the copper liquid in upper reaction chamber again, so that copper melt cinder and copper liquid play more
Good centrifugation, so that copper liquid welds more abundant with weldment, the weldment electric conductivity after welding is more preferable；Further, exist
Lower reaction chamber is placed with the second metal spacer, the second metal spacer can enter one prevent because of metal spacer because of loosen and will react before
Welding powder fall into weldment, the welding powder so fallen into from metal spacer, can be by when copper liquid stream enters lower reaction chamber
The welding powder fusing being placed in lower reaction chamber, thus ensure that weldment only can promote with molten copper liquid phase reactor the most further
Welding quality, then have: the bottom surface of die cap is provided with two connectivity slots, conveniently ignites, and die cap is provided with venting cavity, can accommodate
Suddenly a large amount of gases produced during welding powder burning or explosion thing, and improve the processing safety of weld mold, again can be by logical
Activated carbon in air cavity purifies smog, thus plays more preferable environmental conservation.
