Welding is a process that joins two pieces of metal by heat and pressure. It is one of the most common welding techniques, and it is used to create a variety of objects, including metal plates, pipes, and structural members.
Welding Basics
Welders use different welding techniques to create different types of welds. Here are some of the most common welding techniques.
Gas tungsten arc welding (GTAW): This is a popular welding technique that uses a gas torch to create a weld. GTAW is used to join metals that have different melting points, such as steel and aluminum.
Electrode-arc Welding (EAW): EAW is similar to GTAW, but it uses an electric arc instead of a gas torch. EAW is used to join metals that have a similar melting point, such as steel and aluminum.
MIG welding: MIG welding is a popular welding technique that uses a metal-in-gas (MIG) Welding Gun. MIG welding is used to join metals that have a similar melting point, such as steel and aluminum
Welding Techniques
There are a number of different welding techniques that welders can use to create a weld. Here are some of the most common welding techniques:
Welding with an arc: Welders use an arc to create a weld. An arc is a high-temperature flame that is created when electricity is passed through metal wire. The heat from the arc melts the metal, and the molten metal forms a weld between the two pieces of metal.
Welding with an electrode: Welders use an electrode to create a weld. An electrode is a piece of metal that has been heated until it becomes molten. The molten metal flows onto the electrode, and the weld is created between the two pieces of metal.

Welding electrodes is done by contacting the rod electrode and the workpiece that produces the arc. By connecting the poles, a short circuit between them can be created for a fraction of a second, and it means that current can flow. In some cases, the arc burns between the workpiece and the electrode. When you do that, the resulting heat is needed to produce the fusion reaction.
Arc welding is a type of welding technique that uses an electric arc to produce heat in order to melt and join metals. A power supply is used to produce an electric arc between a consumable or non-consumable electrode and the base material. The current that is used is either direct (DC) or alternating (AC) current.
There are three types of welding electrodes:
Rod: Rod electrodes are the most common type of welding electrode. They are made from a variety of metals, including tungsten, nickel, and copper. They are also available in a variety of shapes, including round, flat, and hexagonal.
Rod-and-bar: Rod-and-bar electrodes are similar to rod electrodes, but they have a bar that is inserted into the end of the electrode. The bar helps to create a better weld and prevents the electrode from becoming misshapen.
Welding wire: Welding wire is made from a variety of metals, including copper, aluminum, and steel. It is also available in a variety of shapes, including round, square, and triangular.
