What are the common pitfalls with induction brazing in a mass production environment, and how can these pitfalls be avoided?
You want to be sure your fixture can present the parts in the same exact place from part run to part run. That’s the biggest variable that leads to non-repeatability with induction brazing processes. You also want to be sure the fixture doesn’t heat up over time and apply additional heat to the part. So as the fixture heats with multiple runs, you want to be sure it can be cooled so it doesn’t add additional heat. The induction coil should not vibrate, which can cause the coil to be move, so anchoring it is important. There are other variables, whether it is induction or not, like the quality of the braze alloy, the braze flux, the consistency of the flux, that are also important.
