Difference Between Welding and Soldering (With Table)

There are many methods when it comes to joining various kinds of metals and processing them. This process includes many known and unknown methods, which are very essential and must be well understood by people. Two such methods are welding and soldering. Although both these do the same work, they have vast differences between them.

Welding vs Soldering

The difference between welding and soldering is that when joining two metals together, there is a need for a strong joint between them, this is where the process of welding takes place, and on the other hand, when there is a requirement for a small joint in resistors or an electronic panel, this is where the process of soldering takes place.

The process which is used for creating a real strong bond between any two metals is known as welding. The piece of metals that have been joined will be Resistant to any kind of strain or stress. This practice is mostly seen in the automobile industry. Pieces of metals being the same, heated with high temperature, etc., are some features necessary for welding.

The process of soldering does relate a lot to welding, but it has Its features too. First, it is a process which used for not only connecting two metals but also two kinds of electronic components together. The machine of solder is available in tubes or the shape of a pipe. Setting low temperature and availability of flux are some necessities of soldering.

What is Welding?

When there is a process of welding between two metals, those two metals have to be of the same type. Welding cannot take place when there are two different metals. For example, stainless steel cannot be welded with brass. The welding process is basically a process that allows to join two metals by heating and setting it to a temperature that allows it to melt.

The process of welding is done in such a way where a machine is heated to a high temperature which helps in creating a molten metal that helps to join two metals together. Sometimes, a weld pool is made by using a filler metal which helps the metal to join even stronger and durable.

When two metals are welded, they are even stronger than wherein their original form before the welding process took place. At the same time, if the process of welding was not carried out properly, then it would have affected the properties and characteristics of metal by weakening it. A worker putting more heat than required in metal is an example of wrong welding taking place.

What is Soldering?

The process of soldering is very close to that of the process of brazing. In the process of soldering, there takes place joining of two metals but with a low set temperature instead of a high temperature. In this process, sometimes fillers are also used. When a melting part cools down, by its own mixes and joins into a metal.

When two metals are joined through the process of soldering, they are not as strong as their original version before they were soldered. There are many varieties of how metals can go through this process, namely soft soldering, silver coating soldering, etc. These different types of soldering processes include having their own characteristics.

The process of soldering is also used to help clean the metals and give them their characteristics and features. It enhances their mental properties. This process is commonly used for repairing and plumbing, and making jewellery. This process doesn’t make the metal strong but does help to join the metals properly.

Main Differences Between Welding and Soldering (With Table)

  1. The process of welding is mostly observed to be used in mechanical industries, and on the other hand, the process of soldering is mostly observed to be used in Electronic industries.
  2. In the process of welding, the temperature of welding is set higher than the melting temperature, and on the other hand, in the process of soldering, the temperature for soldering is set lower than the melting temperature.
  3. The process of welding helps the metals to become a strong mechanical joint, and on the other hand, the process of soldering helps the metals to become a strong electronic joint.
  4. There is no compulsion for using filler metal in the welding process, and on the other hand, there is a necessity of using filler metal in the process of soldering.
  5. When two metals go through the process of welding, there is a change in their properties of those metals, and on the other hand, when two metals go through the process of soldering, there is no change observed in the properties of those metals.

Conclusion

Both the process of welding as well soldering are used for the process of joining two things together. Although both these processes have the same motive, they have vast differences. The difference between welding and soldering lies in how they are characterized, how they perform, how they function, and how they create a mixture by joining.

A person working in different industries should know the differences in these processes and have depth knowledge of a different kind of process that takes place in industries for melting metals. All kinds of processes have their own characters and features in how they carry out their process.
