Objective
Induction Brazing stainless steel to copper tubing. Objective is to evaluate induction brazing solution. Customer is looking to reduce defects and for a cleaner brazing environment.
Due to different pipe size and lower volume – evaluation is performed with a induction brazing system.
Test1
Equipment
DW-HF-25kw induction brazing machine
Materials
Copper to Stainless steel tube
Power: 12.5kW
Temperature: 1400ºF to 1600ºF (760ºC to 871ºC)
Time: 9 to 11 seconds
Test2
Equipment
DW-HF-25kw induction brazing machine
Materials
Copper to Stainless steel
Power: 12.5kW
Temperature: 1400ºF to 1600ºF (760ºC to 871ºC)
Time: 9 to 11 seconds
Results and Conclusions:
Induction brazing test with U open coil was able to braze the parts in 9 to 11 seconds for the full braze cycle.
Operator training with this setup will be minimal.
