Question: What is a good method to attach a large sheet of honeycomb material around the entire outside diameter (OD) of a large 304L stainless steel cylinder so that it can be effectively brazed in place around that OD?

An aerospace brazing company uses a high-temperature AMS-4782 nickel-based brazing filler metal (BFM) when vacuum brazing a high-temperature nickel-based honeycomb material onto the substrate to hold it in place for brazing.

We conclude our discussion on this topic.

What does “mesh size” mean, and what should we be doing about it?

Since it’s been a while, let’s review once again and compare in more detail the differences between correctly performed manual torch brazing and a typical braze-welding process. You might even need to go back and review earlier posts.

Dan Kay fields a reader question about the differences between brazing and braze welding.

How can I keep a tube centered in a fitting for brazing when the dimensions of the tubes and fittings have such broad, loose commercial tolerances and the tube tends to “wobble” inside the fitting?

You mentioned that your brazing cycle was such that the molten BFM was held at brazing temperature for 10 minutes.

BrazeLet 9007/9017 water-based pastes are flux-free, contain low polymer content and prevent oxidation of the filler metal.

I recently read your blog about isothermal solidification (ITS). I want to be sure I understand how it relates to ordinary furnace brazing with the BNi-2 nickel filler metal we use, where the time at temperature is limited to only 10 minutes.
