Braze Welding Sheet Metal

Oxy acetylene gas welding brazing and braze welding.

Braze welding sheet metal.

What is the difference between welding and brazing. This has several negative effects. Let s explore the distinctions plus comparative advantages as well as common applications. Use the right brazing rod material for the metal used in your project.

Brazing is a metal joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint the filler metal having a lower melting point than the adjoining metal. The most common filler metal is brass 60 percent copper 40 percent zinc with additions of silicon nickel or other elements. 3 5 for gas tungsten arc welding gtaw see ses w07 f01. These steels when welded using a traditional arc welding process produce large quantities of zinc vapour.

Brazing is distinguished from welding because it uses an intermediary material usually a copper zinc alloy to join the two metal pieces rather than melting the pieces themselves.

There are several methods available for joining metals including welding brazing and soldering. 3 4 for oxyacetylene braze welding see ses w04 f01.

The biggest benefit to brazing is that sheet metal fabricators can join together similar or different metals and still produce a strong joint. These are older methods of joining thin metal sections that still have some application in today s world of mostly electric welding. Braze welding is welding with a nonferrous filler metal that melts below the melting temperature of the base metal. Brazing is the process of joining two independent pieces of metal to form one strong load bearing joint.

In most cases they will prove inferior in one or more of several ways to electric welding approaches. Brazing is similar to soldering but at higher temperatures. Welding is a more common sheet metal technique but brazing shouldn t be discounted as a reliable process. 3 7 all welding and tack welding shall be done by welders who have satisfactorily passed welder s qualification tests.

The joint is produced by a sweating action of the brazing alloy on the basemetal surface. What is the difference between brazing and soldering.
