Hi guys in this article we study another new topic What's the Difference between DC Arc Welding and AC Arc Welding? both welding process are important in welding processes. so without wasting of time let's discuss further information,
In arc welding arc is produced when two carrying conductors are bring together and then after separated provided there is voltage are present to force of current pass through air gap, and temperature range about 5500 degree Celsius.
What is Comparison between DC Arc Welding and AC Arc Welding?
 |
| What's the Difference between DC Arc Welding and AC Arc Welding? |
| Sr.no. | AC Arc Welding | DC Arc Welding |
| 1) | AC arc welding can be used where AC supply is available. | Its is used any supply with captive generator. |
| 2) | No arc blow problems. | Process suffers from arc blow problems. |
| 3) | In this process transformer is used with because its less cost. | In this process DC generators are used comparatively high cost.
|
| 4) | Maintenance cost is low because of transformer does not not have moving parts. | In DC arc there is moving pars in generator making more maintenance. |
| 5) | Reverse polarities can not used. | Reverse polarities can be used as per requirements. |
| 6) | In AC arc there is striking arc problem. | In this problems are easily stuck. |
| 7) | It is not suitable for welding sheet metal. | Suitable for welding on sheet metal. |
| 8) | AC arc welding is not suitable for lower current with tiny diameter electrodes. | DC arc welding suitable for lower current with tiny diameter. |
| 9) | In this welding long long cables used for long distance. | In this welding short cables are used that's why long distance not possible. |
So in this article we learned the topic What's the Difference between DC Arc Welding and AC Arc Welding? hope you understand well.
Any query regarding this article comment below. Thanks for reading.
