摘　　要：Vacuum brazed condenser after pressure test has arch camber and drum bursts phenomenon,It is contrasted for composition、 thermal differential、metallographic analysis systems of part of 434 composite plate. The results shows that the condenser brazing good and bad in the 434 composite brazing sheet composition,grain size,melting temperature,etc. There is no significant difference. Pressure from arch,drum bursts phenomenon should not be assembled with the condenser,fin and other factors affect the strength. And the corresponding process steps.Vacuum brazed condenser after pressure test has arch camber and drum bursts phenomenon,It is contrasted for composition、 thermal differential、metallographic analysis systems of part of 434 composite plate.
