Objective
Evaluate replacing of flame copper t pipe brazing with induction brazing.
Equipment
DW-HF-25kw high frequency induction heating machine
Materials
• Copper main tube – 1.13” (28.7 0mm) OD 1.01” (25.65 mm) ID
• Riser tube copper – 0.84” (21.33 0mm) OD, 0.76” (19.30 0mm) ID
Power:
Power manually reduced from max output of 10kW to 15kW to provide even heat distribution on the assembly with the modified test coil.
NOTE: Heat time can be improved with custom coil design.
Temperature:
Approximately 704° C (1300° F)
Time: 25sec
Process Steps:
