Welding is a process that joins two pieces of metal by heating them together until they form a joint. Welding is used in a variety of applications, including construction, manufacturing, and repair.
Welding techniques can be divided into two categories: gas and electric. Gas welding is typically used for small pieces of metal that are joined together quickly, while electric welding is more suited for larger pieces that need to be joined over a longer period of time.
Welding Equipments
Welding equipment can be divided into two categories: consumable and non-consumable. Consumable welding equipment includes tools like torches and welding rods, while non-consumable equipment includes things like tanks and power sources.
Welding Techniques
There are a number of welding techniques that can be used to join metal pieces together. The most common techniques are gas and electric welding, but there are also others, like arc welding.

Gas welding is a type of electric welding that uses a gas to produce heat. Gas welding is used for small pieces of metal that are joined together quickly, while electric welding is more suited for larger pieces that need to be joined over a longer period of time.
To use gas welding, you first need to choose a type of gas. There are three main types of gases used in welding: MIG (metal-in-gas), TIG (tungsten-in-gas), and FCA (flooded-copper-arc). Each has its own advantages and disadvantages, so you need to choose the right gas for the job at hand.
MIG welding uses a low-pressure gas that is delivered through a torch. This gas is made up of argon, helium, and oxygen, and it is used to produce a hot, gas-based arc. MIG welding is best suited for small pieces of metal that are joined together quickly.
TIG welding uses a high-pressure gas that is delivered through a torch. This gas is made up of helium, argon, and oxygen, and it is used to produce a hot, gas-based arc.
FCA welding uses a low-pressure gas that is delivered through a torch. This gas is made up of hydrogen and carbon dioxide, and it is used to produce a hot, arc-based flame. FCA welding is best suited for joining copper pieces together.
Welding with Gas Torch
The use of a propane torch makes welding safe, simple, and efficient. Propane torches are often referred to as air-fuel torches because they burn a mixture of propane gas and oxygen. When this mixture is ignited, it produces a clean-burning flame that is suitable for heating or welding purposes.
A blowtorch is a tool that uses combustible gas to weld two metals together. Using a blowtorch, you use a gas-fed flame to heat the work piece, in order to make a weld. You can use straight gas or a mixture of fuel gas and oxygen to start blowing away a blowtorch. The fuel gases used in this project include acetylene, propane and hydrogen.
Electric Welding
Electric welding uses an electric current to produce heat. Electric welding is used for small pieces of metal that are joined together quickly, while gas welding is more suited for larger pieces that need to be joined over a longer period of time.
To use electric welding, you first need to choose an appropriate power source. There are two main types of power sources used in welding: AC (alternating current) and DC (direct current).
