Interplay Learning - Brazing with a Nitrogen Purge

Brazing is a critical skill in HVAC and refrigeration work, essential for creating strong, leak-free joints in copper piping systems. This course introduces learners to the principles of brazing, including how it differs from soldering and welding, proper joint fit and cleanliness, and the science behind capillary action. The course also explores the formation of copper oxide scale, its impact on system performance, and how flowing dry nitrogen during brazing prevents contamination. Learners will gain step-by-step guidance on brazing with nitrogen, understand the tools and procedures involved, and learn best practices for brazing safety in the field.
