Braze Welding Sheet Metal

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.

Braze welding sheet metal.

The joint is produced by a sweating action of the brazing alloy on the basemetal surface. 3 5 for gas tungsten arc welding gtaw see ses w07 f01. 3 4 for oxyacetylene braze welding see ses w04 f01. Brazing is the process of joining two independent pieces of metal to form one strong load bearing joint.

These are older methods of joining thin metal sections that still have some application in today s world of mostly electric welding. Oxy acetylene gas welding brazing and braze welding. 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.

Brazing is a technique for joining pieces of metal together by filling the join between the two metal pieces with a molten intermediary metal. These steels when welded using a traditional arc welding process produce large quantities of zinc vapour. The biggest benefit to brazing is that sheet metal fabricators can join together similar or different metals and still produce a strong joint. The most common filler metal is brass 60 percent copper 40 percent zinc with additions of silicon nickel or other elements.

This has several negative effects. Brazing is similar to soldering but at higher temperatures. There are several methods available for joining metals including welding brazing and soldering. 3 6 for weldments of sheet metal see ses w06 f19.

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. What is the difference between welding and brazing. The braze welding process is considered an excellent choice for the joining of coated eg galvanized thin sheet steels.
