brazing copper plates overlay joints

Objective The objective of the application test is to braze copper and brass plates overlay joints with induction to replace torch operation. Overylay joints may be brass to brass or copper to copper. The current torch process results in excessive contaminants on the assembly and requires extensive rework after the brazing operation.
Equipment DW-HF-25kw induction heating machine   Materials • Copper and brass coupon plates • Braze alloy – EZ Flo 45
Key Parameters – Copper plates Power: 15 kW Heat to Temp: Approximately 1350° F (732° C) Time: Average time – 2 minutes Process and Results:
  1. EZ Flo 45 braze wire was cut into 2” (50.8mm) lengths and placed in the interface area.
  2. The assemblies were set up (see photos) and heated with induction heating for an average time of 2 minutes to flow the alloy and achieve the braze.
