What is welding and how many types are there?
Welding can be considered a process in which two metal and even non-metal parts are connected to each other by heating the joint or melting the joint. In the process of welding, it is very important to pay attention to the welding parameters, and if this is not paid attention to, a suitable product may not be produced in the end.
Heating and melting materials can be done in different ways, so welding also has There are different types and methods, each of which is used in different industries. Among their main methods, the following can be mentioned:
solid state welding
resistance welding
oxygen gas welding
electric welding
various types of welding
Other miscellaneous methods
Types of gas welding (oxygen gas welding (OFW))

The most widely used type of welding is gas or oxy-gas welding. (In some cases, it is also called oxyacetylene welding.) In this process, a hand torch that creates a flame from the combustion of oxygen and acetylene is used together with a filler rod for welding. Many gases are used in all types of welding. Click to read more about the types of welding gas.
Welding with propane gas
In this type of welding, which is known as oxygen welding in the industry, propane is burned together with oxygen gas and heats the joint.
Welding with gas and pressure
In this type of welding, first the flame is used for heating and then the pressure is used for connection. This type of welding is now obsolete and is not used.
Acetylene air welding
In this type of welding, chemicals are used to improve the welding process, this type of welding has very high weaknesses, which is why they have very few fans.
Welding with oxygen acetylene
In this type of welding process, by combining oxygen and acetylene, the parts are heated to a very high temperature, and this high temperature causes a very accurate welding, among other advantages of this type of cheap welding. being the items used in it.
Hydrogen oxygen welding
In this type of welding, a combination of hydrogen and oxygen is used to create a weld.
