There are two main types of welding are arc welding and gas welding. Both of these are used for joining together metals and which is depending on the nature of the job. So here this article gives the more key difference between the Arc welding and the gas welding to better understand this topic.
What is Arc welding?
An electric arc is established heat for fusing the bases metals for coalescence formation. The electrically conductive metal is only applicable to arc welding. It is the process of joining together metals using some electricity. To keep it simple, and while welding the electricity creates an electric, at that time the arc itself produces high heat that melts base metals with filler wire allowing to fuse them into a solid piece.
What is Gas Welding?
Heat is supplied using a frame produced by the chemical combustion of gaseous fuel with oxygen. Electrical conductivity has no role in the gas welding process.
Difference between Arc welding and gas welding:
- In the arc welding, electricity is used to generating heat, while in gas welding, fuel gases like acetylene, hydrogen are used to generate heat.
- In Arc welding consumable electrode is used, while in Gas welding non-consumable electrode is used.
- Arc welding generates stronger joint compare to gas welding, while in Gas welding gives weaker joint.
- This welding generates higher temperatures than gas welding. The temperature is about 6000C, while in gas welding generates lower temperatures than arc welding. The temperature is about 3600C.
- The initial cost of Arc welding is high, While in Gas welding setup cost is low.
- The speed of Arc welding is high, the speed of Gas welding is less efficient.
- Arc welding is more efficient, while in Gas welding is less efficient.
- The heat is concentrate in Arc welding, while in the heat is distributing according to the flame. There is a higher loss of energy.
- Arc welding can be used in welding alone, but in Gas, welding can be used in welding, Brazing, and soldering.
- The electrode is combined with the filler metal in Arc welding, while in a filler rod is used separately if required in Gas welding.
- There is a risk of explosion due to high voltage in Arc welding, while in Gas welding there is a risk of explosion due to high pressure.
- Arc welding is mostly used in joint similar material, while in Gas welding is mostly used to join both similar and different methods.
- The electrical power supply is a prerequisite for every arc welding, while in GAs welding no such power supply is desired.
