What is An Arc Welder

Welding is not something in which you only deal with a singular process. Depending on the type of material its delicacy the joining approach much more you have to opt for other processes like MIG. However, if you are not familiar with what an arc welder is, this post will be a worthwhile read!

Below we shall take a quick overview of an arc welder and its processor working so that it helps you find your quarry. Before you proceed, we recommend you follow the safety guideline to keep from injury or damage to the material.

What is an arc welder?

Arc welding is a process of welding in which electricity is used to bring about the heat which then melts and joins the materials that need to be welded. In arc welders, the strong power supply is what makes the electric arc between a consumable and the non-consumable electrode. The base material can either use the direct (DC) or alternating (AC) current. An arc welder is looked up to for its efficient power to deal with practically thin metal by delivering the powerful welding joint.

How does it work?

Arc welding works on the fusion process to join and weld the metal together. The electrically made arc from AC or DC current makes the most intense heat which is around 6500°F. This heat melts down the material to make a strong weld. The arc from the arc welder can be operated either mechanically or manually and the electrodes feature the electric current or melt into the weld pool simultaneously. The metals in arc welders act chemically to oxygen and nitrogen in the air especially when they are exposed to heat or high-temperature range.

Where arc welder is used

Its efficiency and powerful material joining output and arc welder makes it ideal performance in industries. Mainly the aerospace industry leans on an arc welder to make, manufacture or even repair old aircraft. Also to join sheeting an arc welder is of great usability. Moreover, the automotive industry also uses professional arc welders, especially for the bond exhaust systems and hydraulic lines.

The productivity of arc welders needs no introduction. From construction, industries to making bridges, buildings, and other architectural innovations to many more you can find its presence appreciating.

Types of arc welding

As a rule of thumb, the arc welding process has two major types namely; consumable electrodes and non-consumable electrodes type. In consumable electrode arc welding, we have the following types:

  • Shielded Metal Arc Welding (SMAW)
  • Flux Cored Arc Welding (FCAW)
  • Submerged Arc Welding (SAW)
  • Electro-Slag Welding (ESW)
  • Arc Stud Welding (SW)
  • Metal Inert Gas Welding (MIG) and Metal Active Gas welding (MAG)

Whereas in non-consumable electrode arc welding we have:

  • Tungsten Inert Gas Welding (TIG)
  • Plasma Arc Welding (PAW)

Conclusion

Due to the utmost and unlimited advantages of arc welders, it is being used for a variety of material joining. With the high-speed weld with simple welding apparatus, you get to pick the most efficient welding approach provided you have followed the safety guidelines.
