BoxIT EAD is an information technology company manufacturing its own cooling systems and a part of the process requires brazing of copper pipes. They are searching for a high-quality and controllable brazing technology to incorporate into their manufacturing process.
They tested brazing with a flame torch, a Brown’s gas torch, and induction brazing with the Ultraflex UltraHeat SM (5kW). They determined that induction brazing significantly outperformed the other methods. The Ultraflex equipment provided a perfect braze, producing clean and professional joints.
The induction brazing tests successfully brought the BoxIT copper pipe samples to 750C in under a minute with a variety of brazing alloys, using a power of 5.0kW with a custom heating profile.
The results of the BoxIT heating technologies tests for their copper pipe brazing application.
Ultraflex Induction Brazing
• Great, “perfect” quality samples. Clean and professional joints
• Hardness of pipes unaffected
• Highly controllable braze
• Can program up to 9-step heating profile to ensure consistent results
Flame Torch Brazing
• Emits fumes while heating
• Oxidizes the pipes
• Unclean, discolored copper
• Slow process
• Inconsistent brazing that depends on the operator
Brown’s Gas Torch Brazing
• Very expensive technology
• The flame and heating are concentrated in only one location
• Process is difficult to control and may melt pipes
• Inconsistent brazing that depends on the operator
Induction Brazing
Induction Brazing is a process for joining similar or dissimilar metals using a filler metal using the precision heating of an RF induction heating unit. Additional information about Induction Brazing can be found below.
