Braze Welding Sheet Metal

What is the difference between welding and brazing.

Braze welding sheet metal.

The most common filler metal is brass 60 percent copper 40 percent zinc with additions of silicon nickel or other elements. The biggest benefit to brazing is that sheet metal fabricators can join together similar or different metals and still produce a strong joint. 3 4 for oxyacetylene braze welding see ses w04 f01. 3 5 for gas tungsten arc welding gtaw see ses w07 f01.

Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal. Brazing is the process of joining two independent pieces of metal to form one strong load bearing joint. The joint is produced by a sweating action of the brazing alloy on the basemetal surface. Let s explore the distinctions plus comparative advantages as well as common applications.

Welding is a more common sheet metal technique but brazing shouldn t be discounted as a reliable process. 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. 3 6 for weldments of sheet metal see ses w06 f19. 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.

Braze welding is welding with a nonferrous filler metal that melts below the melting temperature of the base metal. The braze welding process is considered an excellent choice for the joining of coated eg galvanized thin sheet steels. What is the difference between brazing and soldering. Oxy acetylene gas welding brazing and braze welding.

This has several negative effects. There are several methods available for joining metals including welding brazing and soldering. In most cases they will prove inferior in one or more of several ways to electric welding approaches. 3 7 all welding and tack welding shall be done by welders who have satisfactorily passed welder s qualification tests.

These steels when welded using a traditional arc welding process produce large quantities of zinc vapour. These are older methods of joining thin metal sections that still have some application in today s world of mostly electric welding.
