Brazing Copper Sheet

Heat the joint where the two pieces of metal will meet.

Brazing copper sheet.

Brazing is suitable for small parts and when high joint strength is required. The equipment in this project can be bought for as little as 30 dollars. Make sure that you add some flux to the area to be soldered. Four processes to consider when joining copper and copper alloys are mechanical couplings welding soldering and brazing.

Quick and easy brazing aluminum copper and nonferrous metals. Brazed metal can also be stronger then w. I use a paste flux which is self cleaning although you should still wipe it with some isopropyl alcohol afterwards. Brazing copper with the henrob 2000.

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. Brazing is a quick and inexpensive alternative to welding. In this case i m soldering a copper reducer to a piece of copper pipe. Sheet copper copper bars and a lap joint in copper sheet.

Brazing is also much easier then welding it s a lot like using a glue gun. 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 takes place above 840 degrees f but below the melting point of the base metal source. In most cases an overlapped joint will be stronger and braze together easier than a.

In brazing this filler material lays on top of the two pieces of base metal and acts as an adhesive force rather than fusing with the base metals completely. There are a few techniques for adding filler wire to a tig braze properly. Traditionally this was the filler used to finish cramped joints before hard solder became available. Steps use the wire brush or emery cloth to scuff the surface of the metal.

Hard solder is a copper silver alloy that melts at a lower temperature than braze metal. Cda copper tube handbook. It takes skill to make the joint neatly. Brazing using a filler of high zinc brass it is easy to make brazed joints in copper items.

Place the 2 pieces of copper brass you want to solder on a hard surface. Position the metal as desired.
