Objective
The customer needs to braze Copper tubing to Copper tubing using brazing alloy, and flux. The copper tubing is in a variety of shapes, and is not always easily positioned using a traditional heat station. Therefore, the customer would like to utilize the Ultraflex UBraze Handheld Brazing System. There are no time restrictions.

Equipment
UPT-W10 Power Supply
UBraze Handheld Brazing System

Materials
• Copper Tubing
• T Coil, to allow ideal positioning with copper tubing joints
• Brazing Rod
• Flux

Key Parameters
Temperature: about 1400°F (760°C)
Power: 8.43 kW
Time: No time limit was established. The braze took about 3 minutes from start to finish.
Frequency: 148 kHz

Process for Brazing Copper to Copper:

  1. The copper tubing was fitted together, with flux applied at the joint.
  2. The operator held the UBraze Handheld Brazing System with the coil positioned at the joint. The operator pulled the trigger and applied the brazing rod.
  3. With a T coil, the metal does not heat where the coil is open. Therefore, the operator made small adjustments in the coil position to allow for even heating and a good braze throughout the joint. Brazing rod was applied to the joint area throughout the heating.

Results/Benefits:

  • Precise control of the time and temperature
  • Power on demand with rapid heat cycles
  • Reduction in defects due to overheating
  • Repeatable process, not operator dependent when parts are set in a nest or fixture
