Use the right brazing rod material for the metal used in your project. 3 7 all welding and tack welding shall be done by welders who have satisfactorily passed welder s qualification tests. Let s explore the distinctions plus comparative advantages as well as common applications.

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. In most cases they will prove inferior in one or more of several ways to electric welding approaches. 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. Welding is a more common sheet metal technique but brazing shouldn t be discounted as a reliable process.

The most common filler metal is brass 60 percent copper 40 percent zinc with additions of silicon nickel or other elements. The braze welding process is considered an excellent choice for the joining of coated eg galvanized thin sheet steels. These are older methods of joining thin metal sections that still have some application in today s world of mostly electric welding. Brazing is the process of joining two independent pieces of metal to form one strong load bearing joint.

The biggest benefit to brazing is that sheet metal fabricators can join together similar or different metals and still produce a strong joint.

These steels when welded using a traditional arc welding process produce large quantities of zinc vapour.

This has several negative effects. Oxy acetylene gas welding brazing and braze welding. There are several methods available for joining metals including welding brazing and soldering. The joint is produced by a sweating action of the brazing alloy on the basemetal surface.

What is the difference between brazing and soldering. Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal.
