Brazing is a very important metal-joining technique that continues to grow in usage each year in many industries around the world. Most people are familiar with welding and soldering, but many are not familiar with where brazing might fit into the overall metals-joining landscape.

Some of the brazing paste we purchased has separated, showing a layer of liquid above the brazing material in the containers.

Welcome to my part of “Technical Talk,” where we will discuss brazing, a very important metal-joining technique that continues to grow in usage each year in many industries around the world. Most people are familiar with welding and soldering, but many are not familiar with where brazing might fit into the overall metals-joining landscape.

Let’s conclude our discussion of magnesium and brazing.

Does magnesium (Mg) vaporization in a vacuum furnace only occur as a so-called “mag burst” near the brazing temperature of aluminum, or can it occur at lower temperatures?

Question: I was torch brazing a large-diameter copper tube into a copper fitting and built up a nice fillet on the top of the joint at my customer’s request. Someone told me that the joint I made was not a properly brazed joint but was a braze-weld instead. What did he mean? How does braze welding with a torch compare to what I thought I was doing?

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.
