Arc welding uses electricity to join metal, in this case, steel. In contrast to the majority of other methods, which often employ gas, this method makes use of electricity to provide enough heat to melt the metal and join it together during cooling.

Arc welding is frequently used in a variety of significant building projects, such as:

• Heavy equipment repair
• Pipeline welding
• Steel erection
• Vessel manufacturing
• Tank welding
• Construction of ships, rails, bridges, roofs
• Pressure vessels

In the latter half of the 19th century, arc welding was initially created and was employed in shipbuilding during World War II. This procedure has emerged as one of the quickest and most popular welding methods in today's manufacturing businesses.

Advantages of Arc Welding

Compared to many other welding methods, arc welding has many benefits. Among the advantages of arc welding are:

Cost

Arc welding gear is reasonably priced and cost-effective, and since gas isn't used, the method frequently starts off needing less equipment.

Portability

It is simple to bring the welding equipment for operations outside because it is portable. Where there is electricity, its power source can be utilised. Alternatively, generators can be used as a backup if no electricity source is available.

Durability

There is no need to clean the surface, and the process of arc welding can be performed immediately on unclean metals. Besides that, it also has a high impact strength and low corrosion resistance. Any environment is suitable for the process of arc welding, and the beads can be used to make designs on delicate metals.

Great results

With arc welding, smooth welding and strong joints can be achieved with minimal distortion at a high speed compared to other welding techniques. 

Minimal Storage Space

The equipment needed for arc welding is small and light; thus, there isn't much storage space required. Businesses with little storage space will find this to be beneficial because they can accommodate arc welding equipment without any issues or challenges.

Disadvantages of Arc Welding

Let's take a closer look at the disadvantages of arc welding and why some welders may want to use another method for their projects instead.

Lower efficiency

Arc welding typically produces more waste than many other techniques, which can sometimes result in an increase in project costs.



Requires high skill level

Arc welding project operators require a high level of expertise and training, which not all specialists have.

It does not work well on thin metals

Some thin metals cannot be welded using arc welding. 

Safety Issues Relating to Arc Welding

Improper safety measures can make welding a risky and harmful activity. Welding requires the use of an appropriate PPE (Personal Protective Equipment) Kit. The primary health-related issues are as follows:

Inhaled substances

Welders are exposed to a variety of potentially hazardous materials while welding. The smoke created, for instance, during flux-cored welding contains a number of hazardous oxides. Therefore, before beginning any welding procedure, we should shield our faces.

Potential harm to eyes

The eyes can sustain significant damage from the high-Intensity spark produced by this welding procedure. When looking at the welding process directly, the eyes can turn red and cause pain for days. As a result, welding goggles must be worn to safeguard the eyes while welding.

Heat, fire, and Explosion Hazards

Welding can generate a lot of heat since the temperature rise in the core can reach up to 3593 degrees Celsius. The sparks can land on the body, or an explosion could occur. As a result, we need to protect our bodies with appropriate gear while welding. Additionally, we need to watch out for any explosive materials that might be nearby the welding area.
