Gas Welding
|
1.
|
In the arc welding, electricity is used to generate heat.
|
In gas welding, fuel gases like acetylene, hydrogen are used
to generate heat.
|
2.
|
This welding generates higher temperature than gas
welding. The temperature is about 6000C.
|
This welding generates lower temperature than arc welding.
The temperature is about 3600C.
|
3.
|
This welding generates stronger joint compare to gas welding.
|
It gives weaker joint.
|
4.
|
It gives poor surface finish.
|
This welding gives good surface finish.
|
5.
|
In arc welding consumable electrode is used.
|
In gas welding non consumable electrode is used.
|
6.
|
The electrode is combined with the filler metal.
|
A filler rod is used separately if required.
|
7.
|
It can be used in welding alone.
|
It can be used in welding, brazing and soldering.
|
8.
|
There is risk of explosion due to high voltage.
|
There is risk of explosion due to high pressure.
|
9.
|
It is mostly used to joint similar material.
|
It is mostly use to join both similar and different
metals.
|
10.
|
The heat is concentrate in arc welding.
|
The heat is distributing according to the flame. There is
higher loss of energy.
|
11.
|
It is more efficient.
|
It is less efficient.
|
12.
|
Speed of welding is high.
|
Speed of welding is low.
|
13.
|
The initial cost of arc welding is high.
|
The setup cost of gas welding is low.
