When you join two pieces of metal to a third piece of metal that is a filler metal that is molten,Brazing and this type of Welding Articles you have a technique called brazing. This type of welding is said to be versatile and the joints that are brazed have a very strong tensile strength. One reason to use this method is because it can make the two metals stronger when they are bonded then when they are separate metals.

 

One of the good points for brazing is that when you have brazed the joints they will repel gas and other liquids so that the metals can resist vibration and they do are not affected with changes in temperature. They can also resist shock.

 

Also, since the two metals are joined they don't warp or distort but they are able to keep all their metallurgical properties. You will also notice that because the joints themselves are not melted, they come out very clean and you have a nice finish.

 

Brazing is usually used for the manufacture of plumbing fixtures, for making tools, used in high quality products for consumers and in heavy construction. You can use this process when you want to join two metals that are different. This is also a quick and very cost effective method.

 

When you are considering what welding process to use it is a good idea to think about the total project and what you want it to do. When you want a strong and permanent fixture then brazing is a better technique. One of the reasons this is a better technique is because it is more flexible than other forms of welding and you can make mistakes that can be easily corrected and changed as you go.

 

 Brazing can also be used with thin metals because you won't have a lot of warping or distortion. You can also braze linear joints a lot easier than with welding because the filler metal that you use will automatically flow to the joint you are trying to bring together.

 

There are three ways for you to have the heat that you need for brazing. These three ways are: using a hand held torch, using a furnace or you can use an induction heating system. You can use torch brazing for small areas, but you will have to practice this a bit before you do it on something important. The reason is because you have to have a steady hand and be able to control the movement of the torch.

 

There are basically three types of brazed joints:

 

Butt joint -- this is when you have two metals that you want to join end to end. This is a strong brazing when you have enough bond surfaces to work with.

 

Lap joint -- this type of joint is used when the welder wants a strong bond. The two metals will be overlapped which makes a larger surface to bond, and a stronger bond.

 

Butt-lap joint -- when these two types of joints are brought together, they create one single thickness and a strength that is stronger then the two individually.
