Brazing with flux image
By Harris Products Group

Why is flux required when brazing brass and not required with copper to copper?

A fluxing agent (or a controlled atmosphere as found in furnace brazing) is required for all brazing and soldering applications. The purpose of the flux is to remove oxides from the base material and to prevent oxidation during the heating process, thus promoting the free flow of the brazing filler metal.

What is solidus and liquidus and why is it important to brazing?

If you look at a list of brazing filler metals you’ll note many compositions and a variety of melting temperatures. The melting characteristics of brazing filler metal are an important aspect in filler metal selection. Here's a brief outline of how alloys melt and the way to use this information to make the best selection.

Will a Check Valve stop a Flashback?

A flashback is an uncontrolled flame that recesses back into your oxy-fuel gas equipment, upstream of the location where the gas is designed to mix. In order to have a flashback you must have oxygen and fuel mixed together.
