Induction Brazing Copper Pipe Fittings

Induction Brazing Copper Fittings Objective: Copper 'tees' and 'ells' are to be brazed to the aluminum body of a refrigeration valve Material: customer's valve copper fittings braze Temperature: 2550 ºF (1400°C) Frequency: 585 kHz Equipment: DW-UHF-10kw induction heating system including a workhead containing two 1.5μF capacitors (total 0.75μF) and a three-turn helical coil Process: The valve is placed inside the coil and RF induction heating power is applied until the part is heated to the required temperature and the braze is seen to flow into the joint. Two tube sizes were run using the same induction heating system settings with differing cycle times. Results/Benefits • energy is applied only to the zone to be heated • heating of the joint/braze is uniform and repeatable https://dw-inductionheater.com/induction-brazing-copper-pipe-fittings.html?feed_id=230886&_unique_id=655782768f6d8
