Title Experimental study of the induction brazing of copper
Abstract
The subject of the use of the country rhyme WH series of high-frequency induction heating power supply, brass brazing copper-phosphorus brazing T2 copper high-frequency induction brazing welding，achieve of copper - copper metal brazing trials showed good weldability. Obtained through the induction brazing process test brass brazing T2 copper best soldering temperature of 950 ° C; copper-phosphorus brazing T2 copper soldering temperature of 700 °C. Mechanical properties testing, brass brazing T2 pure copper shear strength of 175MPa, the brittle fracture; T2 copper, copper-phosphorus brazing filler metal shear strength of 202MPa, the ductile fracture. Metallographic tests showed that the brass brazing filler metal organization for the Cu-Zn alloy, for α + β phase; the organization of the copper-phosphorus brazing filler metal Cu-P alloy, for α + β phase.
