Brazing is the process of joining metals (copper, brass, bronze, steel, and stainless) together.  Using the Oxygen Acetylene Torch, heating the metals to be joined and flowing bronze between the metals.  This provides a strong bonding of two or more metals. 

To learn to braze is mostly about doing. Spend a little time with the torch and you can quickly develop the skill.  

Brazing, using the bronze filler rod is much stronger than soldering.

Brazing not only allows you to join metals together, the bronze filler overlays the joined metals leaving bronze colored points of contact  which adds a rich contrast with the other metals.  

Although the main purpose here is to braze metals together for metal sculpture, you will find it useful for numerous repairs around the home and workshop. 

If something breaks, often you can  just braze it back together.  Meaning that you don't have to go out and buy a replacement. (Saving you time and money!)

Gas Welding is another use for the Oxygen Acetylene Torch.  Gas Welding generally refers to welding steel.  

Gas Welding is a bit stronger than brazing. It's an inexpensive way to join two pieces of steel together.

Although this video focuses on brazing, Gas Welding is covered in the video with a hands-on demonstration of fusion welding and gas welding using the steel filler rod.
