The Positives And Negatives Of Arc Welding

In general, the process of joining any two metals is popularly known as welding. Arc welding is a type of welding which involves combining two metals by using the electricity. That is, it joins any two metals with the help of electric current. The required heat needed for joining the two metals is produced by the electric current used. It is the most easy and reliable and readily available welding process. Arc welding is also known as stick welding. You can know more about arc welding on www.lincolnelectric.com

The main reason why this arc welding is easily available is because of the process simplicity. The arc welding process is so simple to perform.  Both direct and alternate currents can be used for arc welding. Similarly, it can use both non-consumable and consumable electrodes. The temperature of arc can rise up to 6,500 degree. It is used for different purposes like heavy equipment repair, steel erection, and pipeline welding and in some other construction projects.

The electric current is used to heat the metals to so high a temperature that they melt. The current used in the welding process can be DC or AC. A flux is formed around the weld area by the electric current, which avoids contamination and provides stability to the arc. After the welding has finished, the flux is removed.

Positives and negatives of arc welding

Like any other process, arc welding has both advantages and disadvantages. Some of the pros and cons of arc welding are given below;

Portability

The first advantage of arc welding is the tools used for this process is easy to portable. Tools like the propane blow torch are easy to carry and move. No other special setting is needed for this and with enough space one can use them in any confined space.

Convenience

The equipments needed for welding is available for cheap rates. Also, these equipments are easily available in almost all hardware stores.

Cost-constructive

The cost of this arc welding is affordable and as the process requires minimum utilization of equipments, it saves cost to a greater extent

No inert gas needed 

Since welding with arcs does not require the use of inert gas at all, that is one requirement less when you use arc welding.

Different metals support

With this arc welding, one can weld any number of metals apart from steel and aluminum. Therefore, this can be used to weld any sorts of metals

Cons of arc welding

Even though there are advantages, arc welding also has cons related to it.

Low level of efficiency

When comparing to other type of welding, wastes are produced more in this arc welding. Thus, in some cases it rise the cost of welding

Difficult to use thin materials

With some thin metals, it is quite tough or difficult to use arc welding

Risk with heat and light 

Unless used safely, with proper helmet and protective glasses, arc welding puts you at the risk of bodily harm with its high temperature and current.

Slag removal

It often requires the removal of slag constantly and it slows down the process
