Brazing refers to the joining of two metals. It is easy to do and substitute the welding part quite efficiently. It most often makes use of torches to join two metals. Propane torches are one such equipment which is popularly used for brazing. These can be easily sourced from any of the hardware store or a plumbing supply house. Metalsmith and jewelry supply firms too can provide propane torches. Mentioned below is the basic process of brazing two metals using a propane torch. Take a look:
Materials Needed
-Propane Torch
-Brazing Wire
Step 1
The very first step in propane brazing is to clean the metal that you plan to braze. For cleaning, one can make use of sandpaper to remove oxidation while acetone should be used to get rid of grease. Also, use simple soap and water solution to remove the remaining dust particles from the metal surface. Now once all the dirt and grease is removed from the metal, rinse it with water and let the clean metal air dry completely. It might take a time of few hours.
Step 2
Next, put the metal over a work surface which is fire-safe. Then arrange the metal to be brazed properly so that it does not move from the point it has been placed. One should make use of either binding wire, or a third hand or a vise for holding the two metals together as depending on gravity alone for handling the metal in place would not be a good idea.
Step 3
Now the next step in brazing process is to heat both the metals that you plan to join together. As soon as the metals arrive at the perfect brazing temperature, brazing wire needs to be applied to the seam. Keep heating the brazing wire till the time it melts into the seam.
Step 4
Lastly, let the metals cool down to the room temperature and you are already done with the brazing process using propane torch.
