Arc welding is a welding process that uses an electric arc to create enough heat to melt metal, it cools and results in the bonding of the metals. This fusion welding uses AC or DC power supply as its source of heat. this power supply creates an arc between a consumable or non-consumable electrode, passing either AC or DC current to the base materials. So here this article gives the advantages and disadvantages of arc welding to better understand this topic.
Advantages or pros of arc welding:
- It is suitable for high-speed welds.
- It is a simple welding apparatus.
- It can work on AC or DC.
- Superior temperatures.
- Less smoke or sparks are involved.
- Portability as a result of the simple equipment.
- High welding speed.
- It is a fast welding process when compared to others,
- It offers strong joints.
- Produces very little distortion.
- High corrosion resistance.
- It has the ability to weld on porous and dirty metal.
- It is the equipment that is inexpensive.
- Its operation can be performed during wind or rain.
- Its power supply can be used where there is electricity and the alternative can use be if there is no electricity but generators.
- Smooth welding is achieved.
- It is a good impact strength.
- Arc welding beads can be used to create designed on fine metals.
- It can be carried out in any atmosphere.
Disadvantages or Cons of arc welding:
- Require skilled welders.
- Cannot be used for reactive metal like AI or Ti.
- Not suitable for welding thin metals.
- Not all thin metal can weld on arc welding.
- Well trained and skillful operator is needed for the task.
- Increases of project costs as wastage is inevitable during the process.
