How To Braze Sheet Metal Together

Now position the metal properly.

How to braze sheet metal together.

How to braze metal apply emery cloth or wire brush to scrape the metal surface. Heat the joint where the two pieces of metal will meet. Then clean the surfaces using soapy water or a. Rest them on top of pieces of firebrick so they are held above the surface of the rotating table.

Brazing is a similar method to soldering and welding and requires the metal to be melted so they can be joined. Since the oxygen and acetylene are stored individually you have more control over the torch s flame. Position the metal as desired. Another method used to join pieces of metal together is brazing.

Brazing may be defined as hard soldering. Use an oxyacetylene torch in most instances to weld brass. Mix a small amount of flux with water to form a paste. In this example i m making some candlesticks welding copper to aluminum.

Brazing produces a much stronger joint than soft soldering but requires greater heat from oxy acetylene flame. Apply this paste to the areas on the metal pieces that will be joined using the brush. Before welding the brass find out the zinc content of the material you are going to weld because zinc has a lower melting point than copper. Typically an overlapped joint will be sturdier and braze together simpler than a.

Typically that would be very difficult to do but with this system it s very easy. In this video i will be brazing steel for another project which will be uploaded to my channel as well as a piece of brass using supplies which yield excell. Glow the joint where two metal sections. Brazing is a method of joining metals by the use of a fusible alloy consisting largely of brass and melting at a temperature above 600 c.

The heat of the metal will melt the filler into the area needing the repair. Move the flame of the torch on and off as needed to melt the rod. In this technique a filler metal is melted and flowed into the joint where the connection needs to be made. Place the two metal pieces on the rotating table.

Steps use the wire brush or emery cloth to scuff the surface of the metal. There are many materials that can be used to make the filler metal. Apply the filler metal by running a brazing rod along the crack or the joint. In most cases an overlapped joint will be stronger and braze together easier than a.
