Brazing & Soldering with Induction Heating

Clean, Consistent, and Flame-Free Metal Joining for HVAC, Copper, and Aluminum Components

Induction brazing and soldering are highly efficient methods for joining metals using a filler material. Unlike traditional torch brazing, induction delivers precise, localized heat to the joint area — making it ideal for applications in HVAC systems, copper piping, electrical contacts, and automotive aluminum parts.

Our induction heating machines ensure repeatable, high-quality joints with faster cycle times and improved safety — all without an open flame.

Why Induction for Brazing & Soldering?

· Flame-Free Heating: Eliminates gas cylinders, fire hazards, and operator exposure

· Targeted Precision: Heats only the joint area, protecting surrounding components

· Fast Heat-Up: Joints reach brazing temperature in seconds

· Clean and Repeatable: Ideal for automated or high-volume production

·  Energy Efficient: Reduces energy waste compared to torches or ovens

Recommended Induction System Configurations

Custom Coils & Process Tooling

We supply custom brazing coils engineered for optimal heat delivery based on joint geometry, material, and filler type:

· Single-turn or multi-turn coils for copper/aluminum tubes

· U-shaped coils for electrical connectors or terminal lugs

· Coil holders, fixture jigs, foot pedals for manual setups

· IR sensors or thermocouples for closed-loop temperature control

· Optional water-cooling systems for intensive brazing cycles

We support quick-change coil designs for different joint types in the same production environment.

Typical Applications

· HVAC Industry: Brazing copper and aluminum tubing, Y-joints, elbows, compressors
