Methods Used to Join Metals

After the industrial revolution, Metal became an essential part of our civilization. We frequently used metal for construction because it always ensures durability and strongness. Usually, metals like iron, aluminum, steel, nickel, titanium, and copper are joined through welding. We have found that there are a variety of methods that Are Used to Join Metals Some methods are including welding, and some are without welding. If you are interested in learning all about this process, then online welding classes are possible to take from home and can train you well in this specific field.

To join two metal people use temporary and permanent methods. Welding, Brazing, Riveting are considered permanent methods, where Crimping, Shrink Fitting are counted as semi-permanent methods. Each process is well-suited for performing different types of tasks. It is compelling to pursue the correct type of joining method for a specific purpose. This write-up will convoy you to different types of joining metal processes.

What are joining methods?

Joining metal is defined as joining two parts of metal with a process. The process may be with the help of heat or without the heat. Either the join is for permanent or for temporary purposes. The join metal process is classified into two different types of methods. 

  • Welding 
  • Without Welding 

Welding is a process that needs heat and pressure. The heat is applying to melt the metal. Pressure in welding is not mandatory all the time. The Welding process is done by following many procedures. According to the process, Welding is classified into five main methods. They are Gas Welding, Solid State Welding, Resistance Welding, Arc Welding, and Thermo Chemical Welding.

Without the help of any pressure and heat, two metals can be joined for permanent or temporary purposes. Those processes are the most effortless process than the welding process. In the Welding process, people have to know the proper technique of Welding. Besides, it’s a risky process.

What methods are used to join metals?

Joining two metals is not always needed for construction work. In our everyday life, we need to do this kind of work. To make some handy craft or kitchen shrink, we need to join metals. Following the welding process in those types of work does not give you proper benefit. It’s a complex process also. There are many most straightforward methods to join metals like the Glue Method, Soldering Method, Brazing Method, Riveting Method, and  Bolts and Nuts Method. Let’s see the details of those methods and their Pros and Cons.

Glue Method

This is the most straightforward and most simple method for joining metals. The finest thing about this procedure is that anyone who has zero experience also can do this. You are required to apply the glue to the surface of the metals and wait until they dry. Sometimes you need to put them under pressure to try it earlier. It is not always required rather it depends on the things which you want to join. 

However, You will find much variety in Glue. An ordinary Glue is not perfect for Join any metals. For metal joining, you need to use Epoxy, Silicone, or Polyurethane Glue. That Glue ensures the most robust durability in the joint part of the metal. 

Pros Cons 
Cheap and Easy Method As compared to the Heating method, it has less durability. 
Able to join any kind of Metal PiecesSometimes it doesn’t ensure enough reliability.
Ensure enough Durability 
Need to Experience to apply this method

Soldering Method

The soldering method is used in the Electronic Circuit board. This type of joining process needs experience and expertness. Because that has to deal with lots of measurement and a tiny particle, this method needs heat to melt the metal. In the Soldering method, different types of metal need to melt by heat. The heat of Solder is connected with iron, and it requires the 600-degree temperature to soften. 

Many metals like antimony, bismuth, brass, copper, and indium are used in the soldering method. There are many types of the Soldering process: soft Soldering, Hard Soldering, and Brazing. Soft Soldering needs 90-450 degrees Celsius temperature, and Brazing requires an upper than 450 degrees Celsius temperature. 

Pros Cons 
Much safer than Welding This method isn’t used for heavy metal. 
Need low temperature to bond the metal Compared to Mechanical Connection, Electrical Connection is weaker.
Effective for Electrical Devices
Has durability as Welding for longtime

 

Brazing Method

Brazing is a method to join two similar types of metal or two different types of metal. In this process, one ferrous metal is melted among the two metals. The melting part of the filler metal joins with another piece of the metal. In this method, 450 degrees temperature is needed to melt the metal. The Brazing method has three kinds of categories according to the process. They are torch brazing, furnace brazing, resistance brazing. 

In the brazing method, Cooper, Brass, Bronze, Silver, Aluminum can be joined. To get a sound-brazed joint, the parent material and the filler material should be structurally compatible. To join the non-similar metal, this method is well known in the industrial sector.

Pros Cons 
Various types of metal can join.This method cant be join hard metal.
A quick process For Aluminum, it requires a different technique. 
This method can be used in pipe fitting.
Cost-effective 

Riveting Method

Riveting is the most commonly used method to join two or more metal parts permanently. Riveting is one of the preceding join metal techniques. Now, this method is dead among the upgrades of the automation process. This method was used in industrial factories for the automation of different types of tools. This method is currently used to join some dedicated tools. This process is much more expensive than any other metal process. The only objective of this method is to join industrial tools in different cases.

Pros Cons 
A safe and reliable method Much Expensive
The join can be removed easily when wanting.
Can join several metals together

Final Word

Joining a metal is everyday work sometimes. Without following the right kind of method for a specific metal joint is nothing but wasting time. Not each particular method is suitable for joining any metal. So knowing about different types of methods is important. We prospect, by going through this write-up you have got a concept about different types of methods. 

Be sure about the specific method before joint a metal. Follow a convenient and easy method by analyzing all the methods discussed above.
